India's Nuclear Energy Journey: A Contrast Between Past and Present Visions

India's Nuclear Energy Journey: A Contrast Between Past and Present Visions

RAJKOT: India's nuclear energy journey and its ongoing privatisation and foreign collaboration efforts have been highlighted by Prof. Anamik Shah, former Vice-Chancellor of Gujarat Vidyapith, in a detailed article. He has presented an accurate analysis of the contrast between Jawaharlal Nehru's and Dr. Homi J. Bhabha's vision and today's'Aatmanirbhar Bharat'and'Make in India '. India's nuclear programme began in the final years of slavery, not after independence. The Delhi-based archives of Nehru on Science and Society of 1989 show that, as head of the Interim Government, Nehru warned Sardar Vallabhbhai Patel about the export of'thorium'from the state of Travancore and categorically insisted that this vital metal should remain in India. Nehru believed that political independence was incomplete without technical and scientific autonomy. After independence, Nehru, along with Dr. Homi J. Bhabha, formulated a strategic framework based on five key pillars: indigenous fuel-technology control, long-term nuclear reactors, and economic security.

Chinese Researchers Claim Potential Flaw in B-21 Raider Stealth Bomber Design

Chinese Researchers Claim Potential Flaw in B-21 Raider Stealth Bomber Design

The B-21 Raider—America’s next-generation stealth bombers—has barely stepped out of the shadows, and already it’s the subject of global scrutiny. A recent claim by Chinese researchers suggests they may have identified a potential flaw in its design. But in the chessboard world of military aviation, not every “weakness” is what it seems. Sometimes it’s a hypothesis wrapped in simulation, wrapped in geopolitics. Here’s what’s actually going on. What are the B-21 Raider bombers and why does it matter? The B-21 Raider is being developed by Northrop Grumman as the future backbone of the US Air Force’s long-range strike capability. A next-generation stealth platform Designed to replace both the B-2 Spirit and the B-1B Lancer, the B-21 is built for a different era of warfare: Deep penetration into heavily defended airspace Long-range nuclear and conventional strike missions Integration with next-gen digital and AI-driven systems It’s also expected to play a key role in the US nuclear triad, making it strategically critical. What makes it technologically unique Unlike older bombers, the B-21 leans heavily into software: Open architecture design: Enables rapid upgrades without redesigning hardware Stealth evolution: Designed to evade a wider range of radar frequencies Digital engineering: Developed using advanced simulations from day one Think of it less like a traditional aircraft and more like a flying system that can be continuously updated—closer to a smartphone than a static machine. What flaw did Chinese scientists claim to find? The claim comes from researchers linked to the China Aerodynamics Research and Development Centre, who used simulation tools to model the bomber’s likely performance. How the simulation was conducted Using publicly available data—images, known dimensions, and general design principles—they created a virtual model of the aircraft. The key tool reportedly used: PADJ-X simulation software. Their analysis focused on: Airflow behavior around the flying-wing structure Stability across different flight conditions Aerodynamic efficiency under stress The alleged weakness The researchers suggested that the B-21’s flying-wing design may present: Potential stability challenges in certain flight regimes Opportunities for aerodynamic optimization Design trade-offs that could affect performance Importantly, they did not claim a catastrophic flaw—more a “room for improvement” scenario. How credible are these claims? Here’s where things get interesting. The claim sits at the intersection of science, speculation, and strategic messaging. The limits of open-source simulations The B-21 program is highly classified. That means: Exact dimensions, materials, and systems are unknown Internal flight control software is undisclosed Real-world performance data is unavailable So any simulation is, at best, an educated guess. It’s like trying to reverse-engineer a locked smartphone by looking at its reflection in a mirror—you might get the shape right, but not the circuitry. Flying-wing designs are not new The supposed “flaw” revolves around the flying-wing configuration—but this design has existed for decades. The B-2 Spirit already uses it successfully. Yes, flying wings can have stability challenges. But modern aircraft solve this with: Advanced flight control systems Real-time software corrections Precision engineering In other words, what looks like a weakness on paper is often handled invisibly by onboard systems. This kind of analysis is routine Military powers constantly study each other’s equipment. The US analyzes Chinese stealth jets China analyzes US bombers Both sides run simulations based on limited data This is less a “breakthrough discovery” and more standard practice in defense research. Why this matters in the bigger US-China rivalry Even if the findings are speculative, they serve a purpose. Strategic signaling Publishing such claims can: Showcase domestic technological capability Signal confidence in aerospace research Subtly challenge US military superiority Information warfare layer In modern conflicts, perception matters almost as much as capability. A claim like this can: Influence public and political narratives Raise questions about expensive defense programs Feed into broader geopolitical competition What makes the B-21 difficult to evaluate from the outside? The B-21 is designed to be mysterious by design. Classified by necessity Most critical aspects remain hidden: Radar cross-section data Engine configuration Electronic warfare capabilities Without these, any external analysis is incomplete. Software is the real “secret sauce” The aircraft’s edge may lie less in its shape and more in its code: Adaptive mission systems AI-assisted decision-making Continuous upgrades to counter new threats That’s something simulations based on external design simply cannot capture. Should the US be concerned about such findings? Short answer: not immediately—but not dismissively either. Why it’s not an immediate red flag No access to classified data No real-world testing validation Known design trade-offs already accounted for Why it still matters Highlights how advanced simulation tools are becoming Shows how quickly adversaries can analyze new systems Underscores the importance of staying ahead in both hardware and software TL;DR Chinese researchers claim a potential aerodynamic flaw in the B-21 Raider The finding is based on simulations using public data, not classified information The issue relates to flying-wing stability—something already managed in modern aircraft Experts view this as routine analysis, not a confirmed vulnerability The bigger story is about technological competition and perception in US-China rivalry Tags: B-21 Raider Bomber

Curiosity Rover Discovers Rock with Potential Pure Sulfur on Ancient Martian Riverbed

Curiosity Rover Discovers Rock with Potential Pure Sulfur on Ancient Martian Riverbed

The rock was found in a place called Gediz Valley Channel. This is an ancient river channel on Mars. Water flowed here billions of years ago. As the rover passed through this channel, it crushed this rock. Scientists noticed that there are many rocks nearby, which look normal on the outside but may have pure sulfur inside. Curiosity project scientist Ashwin Vasavda said that it was like finding an oasis in the desert. Sulfates are salts formed from sulfur dissolved in water. These sulfates are left behind when water evaporates. Sulfates are important for understanding the history of water on Mars. However, very specific conditions are required for the formation of pure sulfur.

FDA Approves Trilogy Transcatheter Heart Valve System for Treating Severe Aortic Regurgitation

FDA Approves Trilogy Transcatheter Heart Valve System for Treating Severe Aortic Regurgitation

The FDA has approved the Trilogy Transcatheter Heart Valve System for treating patients with symptomatic severe aortic regurgitation . It is the first and only TAVR device specifically indicated for high-risk patients with this condition, offering a minimally invasive alternative to surgery. This approval makes the Trilogy THV System the first and only transcatheter device in the United States with a dedicated indication for eligible patients. Symptomatic, severe AR is significantly undertreated and potentially life altering to the tens of thousands of people annually identified as having this disease in the United States alone. The PMA approval is supported by successful results from the ALIGN-AR Pivotal Trial, a prospective, multicenter, single-arm Investigational Device Exemption (IDE) study which assessed the safety and efficacy of the Trilogy THV System in high-surgical-risk patients with symptomatic, severe AR. “With what we have learned about the Trilogy valve from the ALIGN-AR trial, we now have the answer to a question that the cardiology community had struggled with – can we safely and effectively treat patients with severe aortic regurgitation with a transcatheter device? The answer is yes.” said Martin B. Leon, MD, Professor of Medicine and Director of the Center for Interventional Vascular Therapy at Columbia University Irving Medical Center/New York-Presbyterian Hospital, and Global Program Chair of the ALIGN-AR Trial. “The unique design of the Trilogy System — with its locator technology providing secure anchoring even in the absence of calcium — addresses the fundamental challenge that has made AR so difficult to treat. This approval establishes a new standard of care for high-risk AR patients and is a landmark achievement for the field of interventional cardiology.” “This FDA approval is the defining moment for JenaValve and, more importantly, those patients in the United States who have suffered from severe aortic regurgitation with nowhere to turn,” said John Kilcoyne, Chief Executive Officer of JenaValve. “For too long, high-risk AR patients were left with limited options. Our Trilogy valve changes that reality. Today marks the beginning of a new era in the treatment of aortic regurgitation in America, and we are grateful to the FDA, our investigators, the patients who participated in our clinical program, our investors and the entire JenaValve team whose years of extraordinary commitment made this possible.” JenaValve intends to commence launch activity for the Trilogy System immediately with participating clinical study sites, followed by new hospitals across the country. The Trilogy THV System is the first and only transcatheter heart valve in the United States indicated for native, symptomatic, severe aortic regurgitation in patients who are judged by a Heart Team to be at high or greater risk for surgical aortic valve replacement. The Trilogy System was purpose-built to address the unique anatomical challenges of aortic regurgitation. Unlike conventional TAVR valves that rely on annular calcification for anchoring-which is typically absent in AR patients-the Trilogy System features three proprietary radiopaque locators that attach directly to the native aortic leaflets, enabling secure and stable implantation even in the absence of calcium. The locators also provide commissural alignment for precise valve positioning and ensure a reliable seal to minimize paravalvular regurgitation. The system’s large, open-cell nitinol frame is designed to preserve future coronary access.

Blocking Enzyme Caspase-2 May Increase Risk of Liver Cancer, Study Finds

Blocking Enzyme Caspase-2 May Increase Risk of Liver Cancer, Study Finds

Researchers at the University of Adelaide found that a potential treatment for fatty liver could actually cause cancer. Until now, blocking the enzyme caspase-2 was thought to be beneficial for reversing nonalcoholic fatty liver disease. But new research published in Science Advances shows that blocking this enzyme also increases the risk of chronic liver injury, scarring, and cancer with age. Dr. Gurwant S. Lamba, director of gastroenterology and hepatology at Delhi-based Sri Balaji Action Medical Institute, explains the need for the enzyme caspase-2 and the risk of its deficiency. He also shares some natural ways to reverse fatty liver in the early stages. Why the study raises concern?

NASA Prepares to Send Astronauts Around the Moon After Half-Century Hiatus

NASA Prepares to Send Astronauts Around the Moon After Half-Century Hiatus

The United States is preparing to send astronauts around the Moon again after half a century, but the mission has faced repeated delays. Nasa, the US space agency, stated that the stakes go beyond exploration; they include science, technology, and global competition. Nasa is preparing for its new mission, Artemis II, which is part of its new lunar programme. The mission involves sending four astronauts into space on a journey around the Moon and back to Earth. This is set to be the first human mission of this nature since the Apollo programme. The mission is part of the broader programme to create a human presence on the Moon. However, this mission is not intended for landing on the Moon. Instead, it is meant to pave the way for humans to return to the lunar surface. The Moon is believed to retain many secrets regarding our early solar system. Unlike our planet, its surface has remained unchanged for billions of years. As such, it retains its craters and geological history. By examining the Moon’s features and composition, scientists believe that we shall gain more insight into how our planet was formed and how it came to acquire water. Future missions in this programme are planned to explore the South Pole, which humans have never explored. It is assumed that this area is rich in ice, which may be very useful for our mission. Having a strong presence on the Moon is vital for the US in terms of technological and national security. The Moon is also seen as a stepping stone for missions to Mars. The Moon’s gravity is weaker than Mars’, so it will be easier to test all the equipment and the astronauts’ health. Nasa’s plan is to work with private companies to provide supplies and infrastructure. This could pave the way for a new space economy. The Moon may have some valuable resources, including rare elements and helium-3, which could be used for new energy sources. Although this is all still theoretical, it is generating interest from all over. Several issues have contributed to the delay of the Artemis II mission, primarily related to technical refinement and safety rather than a single setback. A major challenge has been the heat shield of the Orion spacecraft, which showed unexpected signs of wear during the testing of the re-entry process. Nasa has had to conduct more studies on the issue to ensure astronaut safety. The life support systems of the Orion spacecraft have also presented a challenge. Any inconsistencies require the spacecraft to be redesigned or extensively tested, thus causing more delays. The Space Launch System (SLS) required additional integration time with the Orion spacecraft to ensure compatibility. Moreover, rigorous testing of essential software and communication systems, vital for mission success and astronaut safety, has been necessary. Supply chain and manufacturing delays have further complicated matters, particularly for specialised components that demand precision. Lastly, NASA’s cautious approach, prioritising astronaut safety for this first crewed mission of the Artemis programme, necessitates resolving even minor issues before launch, extending timelines further. Nasa is rolling back its Artemis II moon rocket to its hangar after a month at Launch Complex-39B due to a helium system issue, delaying the scheduled launch of four astronauts around the moon from March 6 to no earlier than April 2026. The astronauts have entered a quarantine period at Johnson Space Centre, where they will limit exposure to others before moving to Kennedy Space Centre approximately five days before launch. If everything proceeds as planned, the launch is set for April 1, commencing a 10-day mission around the moon from Pad 39B at Kennedy Space Centre.

NASA's Perseverance Rover Uncovers Ancient River Delta on Mars

Ancient River Delta Mars: Just imagine that on Mars, the nearest planet to our Earth, once there was not the silence like today, but the noise of rivers and huge lakes used to make waves. It may sound surprising to you, but this sight of billions of years ago now seems to be coming true to scientists. NASA's Perseverance Rover has used RIMFAX technology to find the layers buried under the surface of Mars that testify to the water system millions of years ago. The discovery of this buried delta, which is 3.7-2.4 billion years old, has brought scientists closer to the biosignature that was sought for decades. NASA's Perseverance Rover has found the remains of an ancient river delta under the surface of Mars. This discovery is also very important because it is about 4 billion years old, which is the largest evidence of the existence of water on Mars so far. The discovery of the RIMFAX rover was hidden 115 feet under the ground.

Indian Hospital Sets New Precedent with Successful Pectus Excavatum Surgery on 10-Year-Old Bhutanese Child

Meanwhile, RN Tagore Hospital has shown a new direction in the correction of congenital structural defects. Doctors claim that they have set a precedent by operating on a 10-year-old Bhutanese child with the'Pectus Up'method. This is the first time in North and East India. The child was suffering from a problem called'Pectus Excavatum'since birth. This causes the middle bone or sternum of the chest to go inward. As a result, the chest appears to be blocked. Initially, it may seem like only an external problem, but with time, complications like shortness of breath, chest discomfort, and reduced physical strength may occur. There is a risk of impact on the heart and lungs as well. According to hospital sources, the child was first examined by Dr. Manujesh Bandyopadhyay, a specialist in cardiothoracic vascular surgery. After he was diagnosed with the disease, the degree of the disease was determined through chest X-rays, CT scans, echocardiography, and pulmonary function tests. Usually, inside the'Prostenum Bar'was removed from the chest through the'Prostenum Bar '.

Uncovering the Geological Marvels of the Hormuz Formations

Uncovering the Geological Marvels of the Hormuz Formations

As the US-Israel war on Iran extends into its third week, all eyes are on the Strait of Hormuz, the critical chokepoint through which a fifth of the world’s energy supply passes. Iran’s effective closure of the narrow strait has disrupted these flows and driven up the price of oil. What has attracted less attention is the more alluring — and geologically more interesting — part of the Persian Gulf region: the anomalously colourful Hormuz formations and mountainous ranges. These surreal, painted formations, salt caves and ochre-stained shores have catalyzed a burgeoning geotourism industry. Here’s a deeper dive into how these geological marvels were formed, why they look so colourful, and what it tells us about the Earth’s past. While conventional mountain ranges are generally forged through the collision of tectonic plates, the mountains in the Hormuz range are, in fact, vast deposits of salts and minerals. So how did that happen? The process of their formation began roughly 500-600 million years ago, during the Late Precambrian to Early Cambrian period. During this time, shallow and mineral-rich seas repeatedly flooded the region. As these waters repeatedly evaporated, they left behind thick layers of salt over the course of millenia. Over time, these salt beds were buried under innumerable layers of marine sediment and volcanic rock. Their emergence into mountains was driven by three distinct geological mechanisms: Tectonic movement: The Arabian and Eurasian tectonic plates collided with each other, compressing the crust and creating deep structural fractures. These fractures acted as “elevators”, forcing the highly pressurised salt deposits towards the surface. Salt flows: As these low-viscosity, high-buoyancy salt deposits flowed towards the surface, they acquired a putty-like consistency. This process is called halokinesis in geology. Eventually, these punched through the crust to form massive domes as well as mountainous islands — such as the island of Hormuz. Chemical weathering: The ascension of these salt pillars also dredged up a mixture of volcanic rock, clay and metal-rich minerals. The continuous exposure of this cocktail of materials to surface water, oxygen and unblocked sunlight catalyzed the process of chemical weathering. This is what gives these formations their kaleidoscopic colours. The iron oxide rusted into a deep shade of hematite red (the same material on the surface of Mars), the limonite (a mixture of hydrated iron and goethite) yellowed and copper compounds turned a striking green due to intensive oxidation, forming a striking contrast against the white of the unreactive halite deposits. This multi-coloured interaction is what we know today as the mountains of Hormuz. The rainbow colours Depicted in the picture attached, the resulting landscapes observed in the Hormuz formation comprise a concentration of over seventy distinct minerals, each of which boasts its own hue. This, in turn has birthed a terrain which differs from all other mountainous ranges in the world and serves as a laboratory for studying salt flow and deep-crustal processes usually hidden kilometres below ground. The evaporitic phenomenon observed in the Persian Gulf region is not an isolated event. The structures of the Hormuz formation are part of a much larger paleogeographic (study of earth’s surface in the past) system. Regions where evaporite deposition and halokinesis occur simultaneously result in what are known as coeval salt basins. These basins extend eastward across tectonic boundaries, continuing through the heavily mined Salt Range in Pakistan and reaching deep into the subsurface geology of northwestern India. Today, the Hormuz formation stands as a masterpiece of planetary chemistry and geological evolution. But the continuing tensions in the Strait of Hormuz threatens both the formation’s geotourism economy and obscures their scientific heritage.

While full-frame cameras dominate the conversation for astrophotography, many APS-C and Micro Four Thirds (MFT) systems punch far above their weight, and the smaller sensor sizes mean they’re lighter to carry when out and about. Despite their small size, some models can certainly compete with the best cameras for astrophotography . Choosing the right APS-C or Micro Four Thirds camera for astrophotography is less about headline specs and more about understanding how you shoot at night and what you want to get out of your images. Sensor size plays a role: APS-C generally offers cleaner high-ISO performance than Micro Four Thirds, but stability, usability and lens choice matter just as much. Plus, they're often more affordable than full-frame models, making them a good choice as a beginner astrophotography camera . Here are some standout APS-C and MFT bodies for astrophotography, each with its strengths depending on your priorities. Best overall Best overall Currently Sony's best and newest APS-C camera with outstanding autofocus and beautiful image quality for multiple photographic genres. Read more below Best for deep-sky Best for deep-sky Due to the limited wide-angle lens catalog, we'd recommend using the R7's 1.6x crop factor with a telephoto lens for lunar or tracked deep-sky work. Read more below Best battery life Best battery life For long overnight shoots and travel photography out in the field, this camera won't let you down, and it has the best battery life in this list.

Read more below Best astro-features Best astro features The OM-5 provides a compact and lightweight setup for astrophotographers on the move who want to keep the weight down — and it has two useful astro features. Read more below Best for handheld low-light Best for handheld low-light work This camera is more of an investment, but its 8 stops of image-stabilization make it fantastic for handheld low-light work as well as tripod-mounted astrophotography. Read more below Why you can trust Live Science Our expert reviewers spend hours testing and comparing products and services so you can choose the best ones for you. Find out more about how we test. Our expert review: ✅ You want one camera to do most things. A versatile APS-C that can handle landscapes, travel and night sky. ❌ You only care about deep-sky work, or you want specialized astrophotography features. 🔎 Sony A6700: A compact and weather-resistant camera with excellent ergonomics, clean high-ISO files and fast focusing. A superb all-rounder for nightscapes and everyday photography. ★★★★ Sony’s A6700 brings the benefits of a modern APS-C back-illuminated sensor and refined handling into a body that’s versatile and happy to take on a range of different types of photography. The 26-megapixel BSI sensor delivers low noise at high ISO, which is critical for night sky work, especially if you’re shooting wide panoramas where dynamic range and clean shadows matter. Built-in 5-axis IBIS (stabilization) is a boon for those “between” shots that can be accomplished handheld, such as twilight landscapes or moments when you’re switching between tripod and handheld work. From an ergonomics perspective, the user interface and menus are comfortable to navigate in the dark, and the electronic viewfinder makes focusing on bright stars a breeze with focus magnification. It’s also nice to see a vari-angled touchscreen, which is a great addition if you’re pointing your camera at the night sky but still want a good handle on your settings. While there’s no dedicated astrophotography mode or built-in tracking, the overall imaging performance and flexibility make this camera a high-value choice if you want great star photos plus everyday photography in one body. Attributes Notes Design Aperture, shutter speed and ISO can all be controlled on the body. Performance 26MP sensor delivers low-noise images. Functionality Comfortable to navigate in the dark. Our expert review: ✅ You want a high-detail APS-C body and you’re looking to print images large. ❌ You need a lot of lens options and a simple workflow. 🔎 Canon EOS R7: A chunky and weather-sealed option with distinctive controls, offering extremely detailed images but more demanding of technique than other cameras on the list. Excellent for high-resolution nightscapes and printing. ★★★★★ Canon’s EOS R7 sets itself apart primarily through its 32.5-megapixel sensor, which gives you lots of headroom when cropping into star fields or capturing large panoramas without losing fine detail. The high pixel count means you can isolate constellations or nebula regions while retaining enough resolution for prints or tight crops. If you’re adamant about printing large reproductions of your photos, this is the setup we’d investigate. The stabilization here is also noteworthy: when paired with compatible RF-S or RF lenses, Canon quotes up to eight stops of correction. Autofocus performance, especially Canon’s Dual Pixel system, isn’t usually top of the list for astrophotography, but as a strong everyday shooter, it works well. High pixel density demands precise focus, as tiny errors in focus show up quickly in star images. Also, a quick word on ergonomics — Canon’s dial and joystick system isn’t for everyone, and we also don’t love the fact that it does away with a top dial, which means navigating different modes can be tricky. Perhaps not a dealbreaker for night sky photographers, but some may find it annoying in day-to-day life. While we awarded it an impressive 5 stars in our full Canon EOS R7 review , it's worth noting that Canon's wide-angle lens lineup is extremely limited, making it a tricky purchase if you're solely focused on wide-angle astrophotography. If, however, you're a deep-sky enthusiast and want to take advantage of the extra reach from the 1.6x crop factor on a full-frame long telephoto lens , the R7 is well worth it. Attributes Notes Design Lack of top dial can get annoying. Performance Sharp 32.5MP images. Functionality Limited lens options for wide-angle. Our expert review: ✅ You want an astro body that provides crisp, clear images of the night sky. ✅ You regularly shoot long sessions or timelapses in the field away from power. ❌ You dislike Fujifilm’s aesthetic or have already bought into a different ecosystem.| ❌ You already own lenses from another system. 🔎 FujiFilm X-S20: A clean, aesthetically pleasing and modern option with excellent controls, strong noise handling and battery life. Ideal for long overnight astro shoots and hybrid creators. ★★★★ The Fujifilm X-S20 quietly ticks all the boxes for astrophotography and more. Its APS-C X-Trans sensor captures clean, detailed night skies, and its excellent battery life, with an estimated 800 shots per charge, means you can comfortably plan lengthy night sessions without constantly swapping power packs. A real plus when you’re out in the wild, away from mains chargers. Fujifilm’s renowned color processing also means more pleasing base files to work with, which is great if you like to share astrophotography without heavy post-processing. Its aesthetic might not be for everyone, and Fujifilm’s color science has a distinctive look that won’t suit every astrophotographer straight out of the camera. Fuji’s lens lineup, especially the fast, wide primes that are ideal for astrophotography, can be more expensive than those of its rivals, so budget carefully for glass. If you’ve already partially invested in a different lens ecosystem, we’d perhaps recommend looking elsewhere, as you might find yourself reaching a dead end quite quickly in terms of availability and finance. Generally, though, there’s a lot to recommend this option, and we especially like the crisp, limited noise images and how the camera deals with low-light scenarios across the board. Attributes Notes Design Limited on-body controls. Performance Crisp images with limited noise. Functionality Great battery life. Our expert review: ✅ You want a stylish camera that doubles for astrophotography and everyday shooting, or you’re a beginner learning the ropes. ✅ You enjoy learning to use manual controls and slower, considered night shooting. ❌ You want the most forgiving low-light performance and need something built for tough environments. ❌ You frequently shoot in cold or wet conditions. 🔎 Nikon Z fc: Beautiful retro styling and capable, but not class-leading in low light. Great for beginners or casual nightscapes rather than hardcore astro work. ★★★★ The Nikon Z fc won plenty of attention for its retro styling, but beneath the classic dials lies a modern APS-C mirrorless camera that can handle most of what an astrophotographer can throw at it. It’s a small camera and its 20.9-megapixel sensor won’t match some of its rivals for sheer dynamic range or noise control at very high ISOs, but it’s plenty capable for a range of different nightscapes. There is a trade-off to be had in the lack of in-body stabilization. Most modern astrophotographers work primarily with a sturdy tripod for long exposures anyway, so the absence of IBIS isn’t a dealbreaker, but it does remove the flexibility for handheld low-light frames that other cameras in this guide offer. Adding to that, there’s nothing in the way of a grip or any other ergonomics that make it easy to use in the dark. It’s a small device and it can sometimes be a bit clumsy to operate. It’s also worth doing your research on lenses, too — Z-mount lenses can be found, but there are fewer on the market than with other systems. Where the Z fc shines is in its handling experience. If you love physical dials and control layouts, and a design that invites you out shooting, this camera is rewarding and fun to use. Just be prepared to pair it with fast glass if you take astrophotography seriously, and be aware of its relative lack of weatherproofing compared to other options. Attributes Notes Design Classic retro styling. Performance Lack of IBIS removes handheld low-light shooting possibilities. Functionality Limited lens options. Our expert review: ✅ You want a cost-effective APS-C camera that’s easy to use, straight out of the box. ✅ You want strong autofocus for night landscapes and aurora. ❌ You prefer flexible handheld low-light photography 🔎 Nikon Z50: Compact and understated. Very good for its price class and an accessible entry point into serious astro photography. If you own heavier lenses, you may find the body a little small. ★★★★ With a 20.9-megapixel APS-C sensor and classic Nikon color science, the Nikon Z50 is an excellent starting point for budding dark sky photographers, and it sits at an appealing price point, too. It produces images with good detail and noise performance when used on a stable tripod for long exposures, and for Milky Way and landscape astrophotography, it does the job well, especially when paired with a fast, wide prime. It’s worth noting that it doesn’t ship with any form of stabilization, which could be a factor if you plan on doing handheld low-light work. One of its biggest advantages is value for money, and this lets you invest more in lenses or support accessories like tripods and star trackers. For beginners or those building their first astrophotography kit, we think that this balance between performance and affordability makes it a very good entry point. Attributes Notes Design Small body is amplified if using large lenses. Performance Good starting point for beginners or the budget-conscious. Functionality No image-stabilization for other styles. Our expert review: ✅ You need something you can throw in a bag and not treat with kid gloves ✅ You like using inbuilt composite and in-camera editing tools ❌ You prefer the cleanest possible high-ISO files. ❌ You’re looking for the latest sensor tech, or you need to print big images 🔎 OM System OM-5 Mark II: Compact, well-sealed and expedition-ready. Excellent for travel, astro and, with in-built features, brilliant for long-exposure experimentation using Live Composite modes. ★★★★ The OM-5 Mark II is one of the most practical cameras for astrophotographers who like to step into the backcountry. Its weather-sealed body and impressive stabilization (quoted up to 7.5 stops) mean you can confidently shoot in all conditions. Micro Four Thirds sensors don’t compete directly with APS-C for high-ISO noise performance, but the OM-5 makes up for it with portability and handling. Compact wide-angle lenses are among the smallest and lightest available, letting you carry a complete astro kit without weighing you down too much. We’d have liked to see a double SD card slot and slightly better battery life (it’s rated for about 310 shots per charge), but the size and lack of weight of the camera mean its strong suit is portability For astrophotographers who value flexibility and enjoy travel photography too, this is a great option — the OM-5 Mark II strikes a superb balance between performance and real-world practicality. Plus, it has Live Composite, Starry Sky Autofocus and a Night Vision mode, all of which are fantastic for astrophotographers. Attributes Notes Design Rugged for tough conditions. Performance Great balance of performance and practicality. Functionality Live Composite, Starry Sky AF and Night Vision mode. Our expert review: ✅ You want the most complete MFT astrophotography tool ✅ You want flagship handling with advanced computational modes. ❌ You want the smallest, lightest possible setup ❌ You mainly shoot casually and want something simpler. 🔎 Panasonic Lumix G9 II: Chunky, professional and class-leading in the MFT world. Superb for nightscapes, timelapse and hybrid work. ★★★★★ The Panasonic Lumix G9 II is the brand’s flagship Micro Four Thirds body on the market now. With a 25.2MP sensor and excellent IBIS (up to eight stops), it handles night sky shooting and everyday photography with equal confidence. Combine excellent resolution and color rendition with advanced autofocus and excellent usability, and you get a camera that feels more modern across the board than many rivals. The body is larger than some compact options we’ve listed here, but that can be a plus at night as more substantial cameras often balance better on tripods and feel more secure under gloves and in poor weather. If you want one MFT camera that handles astrophotography, landscapes, wildlife, timelapse and video without compromise, the G9 II should be right at the top of your list. Attributes Notes Design Larger than other MFT options. Performance Excellent for a range of photographic styles. Functionality 25.2MP resolution. Our expert review: ✅ You shoot hybrid astro stills and video, and want excellent filmmaking tools ✅ You prioritize night video and timelapse production. ❌ You want the simplest stills-only setup. ❌ You want to prioritize lightweight kit. 🔎 Panasonic Lumix GH6: Large and video-centric. Outstanding for motion capture, so ideal for cinematic astrophotography, but you may want to look elsewhere if you’re interested in stills only. ★★★★ The Panasonic GH6 is a powerhouse for astrophotographers who think in both stills and motion. It has a high-resolution sensor and plenty of rich video options, including 5.7K and 4K 10-bit shooting, making it ideal for night timelapses, astro documentaries and immersive night footage. If you’re a content creator or like to combine stills and video, we’d look no further than this. While its body is larger and more complex than many stills-focused MFT models, this is precisely why creators who shoot motion love it: you don’t have to compromise on either side of your workflow. For astrophotography stills, the sensor delivers enough detail, and for video, it provides superb dynamic range and color depth, as well as internal recording in Apple ProRes 422 HQ and 422, pre-installed V-Log/V-Gamut and 13+ stops of dynamic range via Dynamic Range Boost. If part of your astro process includes long night timelapses, behind-the-scenes night videos or content creation alongside still images, the GH6 is one of the most compelling cameras on offer today. Attributes Notes Design Larger than other MFT models. Performance Excellent for stills and video Functionality 5.7K and 4K 10-bit video shooting Our expert review: ✅ You want a robust all-weather MFT body for landscapes and general use, and your work is predominantly on social media or digital. ✅ You like Olympus’s Live Composite shooting modes. ❌ You need the very lightest possible kit, or you need to print large images. ❌ You want the newest sensor generation. 🔎 Olympus OM-D E-M1 Mark III: Rugged and dependable rather than cutting-edge, but excellent for controlled long-exposure night shooting. ★★★★ Although it uses slightly older tech now, this remains a strong astrophotography option thanks to its excellent stabilization and handling. Its 20.1MP sensor isn’t the latest available from OM System (formerly Olympus), but the combination of a good choice of sharp lenses and in-body correction makes it comfortable to use both on tripods for long exposures and handheld for dawn/dusk scenarios. We also like the body’s ergonomic design, and its excellent weather sealing gives you confidence if you often shoot in the wild — a frequent reality at dark sky locations. The reliability and build quality are why many outdoor photographers still choose this model long after its release, and we’d be happy to forgo the latest tech in favor of great performance when on location. Plus, with OM System's 'Starry Sky Autofocus' up its sleeve, you don't have to worry about ending up with blurry, out-of-focus stars. We tested this feature out when we reviewed the OM-1 Mark II , and we found it to be surprisingly effective. Plus, Live Composite shooting enables you to effortlessly create star trail images. Attributes Notes Design Ergonomic design Performance Great performance despite using older tech. Functionality Excellent weather sealing. Camera ISO range Rear monitor Autofocus sensitivity Longest shutter speed Battery life Sony A6700 100-32,000 3.0-inch vari-angle touchscreen, 1.03-million dots Down to –3 EV 30 sec 570 shots (CIPA) Canon EOS R7 100-32,000 3.0-inch vari-angle touchscreen, 1.62-million dots Down to –5 EV 30 sec 660 shots (CIPA) FujiFilm X-S20 160-12,800 3.0-inch vari-angle touchscreen, 1.62-million dots Down to –7 EV 30 sec 800 shots (CIPA) Nikon Z fc 100-51,200 3.0-inch vari-angle touchscreen, 1.04-million dots Down to –4.5 EV 30 sec 360 shots (CIPA) Nikon Z50 100-51,200 3.2-inch tilting LCD, 1.04-million dots Down to –4 EV 30 sec 320 shots (CIPA) OM System OM-5 Mark II 200-6,400 3.0-inch vari-angle touchscreen, 1.037-million dots Down to –2 EV 60 sec 310 shots (CIPA) Panasonic Lumix G9 II 100-25,600 3.0-inch vari-angle touchscreen, 1.84-million dots Down to –4 EV 60 sec 390 shots (CIPA) Panasonic Lumix GH6 100-25,600 3.0-inch vari-angle touchscreen, 1.84-million dots Down to –4 EV 60 sec 360 shots (CIPA) Olympus OM-D E-M1 Mark III 200-25,600 3.0-inch vari-angle touchscreen, 1.04-million dots Down to –6 EV 60 sec 420 shots (CIPA) Yes, APS-C cameras are very capable for astrophotography, especially for wide-field nightscapes. A larger sensor, compared to a Micro Four Thirds, gathers more light and generally produces less noise at high ISO, while keeping cameras relatively compact and affordable. Micro Four Thirds can work very well for astrophotography, particularly in situations where portability matters. The smaller sensor typically produces more noise at high ISO compared to APS-C and full frame, but many modern MDT cameras with good noise processing and specific astro fetures can deliver sharp, detailed night sky images. Full frame generally has the edge because the larger sensor has more photosites (even if it's the same resolution as APS-C), and therefore collects more light, resulting in cleaner high ISO images and better dynamic range in dark skies. The superior signal-to-noise ratio means that full-frame cameras are generally preferred for astrophotography, but APS-C is still a strong and more affordable alternative, offering excellent results in a more portable package. Crop factor narrows the field of view, meaning a lens appears more zoomed in on APS-C or MFT compared to full frame. This can make it harder to capture sweeping milky way scenes with the same focal length. Yes, APS-C can be used for deep-sky astrophotography, particularly when paired with a telescope or telephoto lens and star tracker. While full frame might offer slightly better noise performance, APS-C sensors provide a good balance of resolution, reach (due to the crop factor) and cost. Future updates to this guide will be detailed here. Best astrophotography cameras Best beginner astrophotography cameras Best lenses for astrophotography Best telephoto zoom lenses Best smart telescopes Best telescopes Best small telescopes We test astrophotography cameras by focusing on the factors that matter most in low-light shooting. That includes high ISO noise performance, dynamic range in dark scenes and how well the sensor retains color and details in shadows. We also assess long-exposure reliability, heat management during extended shooting sessions and in-camera features that either help or hinder astrophotography. Handling is equally important. We consider the ergonomics in cold conditions, menu clarity in the dark, battery life and lens compatibility, which is particularly important with APS-C and MFT cameras.

While spring is a lovely time of year to look forward to, for some, it brings about mixed feelings because their hay fever symptoms increase as the weather improves. Hay fever often leaves people with a runny nose, itchy eyes, sore throats, coughs and sneezes. However, there are things you can do to reduce how much pollen impacts you at this time of year, so here are our top five tips on how to survive hay fever season. We spoke to Melanie Carver, chief mission officer of the Asthma and Allergy Foundation of America (AAFA), who offered some expert advice and tips on how to survive hay fever season. One option is to consider one of the best air purifiers to keep the air in your home as clean as possible. Read on to find out what advice the experts give. As soon as spring hits, it's tempting to open the windows and let the fresh air spruce up your home, especially if it's been a long, cold and wet winter. However, for those who suffer with hay fever, this may, in fact, be encouraging those allergens into the home. Pollen travels through the air, so if you open the windows, pollen can enter the home and increase the occurrence of sneezing, itchy eyes and coughing. Melanie Carver, chief mission officer of the Asthma and Allergy Foundation of America (AAFA), explains: "Open windows, even windows with screens, allow pollen to enter the home easily, especially during times when pollen counts are high. Individuals with pollen allergy (tree, grass, and weed pollen are the most common) may experience allergy symptoms if the pollen that triggers their allergies is present in the home. Symptoms may include a runny nose, a stuffy nose, sneezing, itchy and watery eyes and coughing/wheezing. "One of the best ways to manage pollen allergy symptoms is to reduce exposure to pollen. This means keeping windows closed when pollen counts are high and taking steps to prevent pollen from being in your home." While keeping your windows closed in the lovely spring weather might sound annoying, especially if you want to freshen up your home, keeping your windows closed can have other benefits, such as keeping the warm air out of your home and helping to keep it cooler if it is a particularly hot season. Get the world’s most fascinating discoveries delivered straight to your inbox. If pollen does get into the home (which, to some extent, is inevitable), the best air purifiers can help remove these allergens and make your indoor space more pleasant during hay fever season. Air purifiers work by using fans to draw in the indoor air and then passing it through a filter, effectively removing the allergens. The filters trap microscopic particles such as pollen, so these particles never reach your lungs. By removing these particles from the air, this can also reduce the amount of sneezing, itchy eyes and coughing you experience during hay fever season. Our top tip when buying an air purifier for allergies is to get one with a HEPA filter — these are the most effective filters. Our expert, Melanie Carver, said: "HEPA – high efficiency particulate air – filters are an effective way to reduce exposure to common allergens, including pollens. HEPA filters work by using a fine two mesh of fibers to trap particles (such as pollen) and prevent them from being redistributed into the air. Asthma & Allergy Friendly® Certified air purifiers or air filters with HEPA can help reduce your exposure to allergens and airway irritants." The Levoit Core 600S won best overall in our best air purifiers guide . We were impressed with its three-stage True HEPA filter system, which removed 99.9% of particles measuring as small as 0.3 microns, during our testing. This is good news for those with hay fever — the Levoit is a user-friendly option with excellent performance. We reviewed the Molekule Air Mini+'s larger sibling, the Molekule Air Pro , and awarded it the best for large rooms in our best air purifiers guide . Similar to its sibling, this device is FDA-cleared for medical use thanks to its patented pollutant-destroying PECO technology — this turns pollen and other organic airborne particles into water vapor and harmless gases. For your little ones who may be hay fever sufferers, the Levoit Sprout is a good option. Voted as the best for nurseries in our best air purifiers guide , the Levoit Sprout performs well as an air purifier, but also has a built-in white noise machine and night light to help soothe your children to sleep. Plus, it is quiet. To some, this might seem a bit extreme, but pollen and other allergens can get trapped on fabrics while you're out and about. Pollen is an airborne particle, meaning it moves around in the air, but it also attaches itself to various surfaces once it comes in contact with them. Therefore, changing your clothes when you get home can reduce the risk of further irritation to your respiratory system later in the day. As pollen can also get trapped on your hair and skin, it isn't a bad idea to shower and wash your hair upon returning home for the day, either. "AAFA recommends changing clothes after you’ve been outside on high pollen count days. This is one way to help reduce your exposure to the pollen that may trigger your allergy symptoms," said Melanie Carver. "Put dirty laundry directly into your washer, or at least not in your bedroom. We also recommend washing your hands as well as washing your hair to help remove pollen. For people who can’t or don’t want to wash their hair that often, use a hair covering when outside to prevent pollen from collecting on one's head. "Additionally, we recommend wiping down your pets when they come in from outside to help keep them from spreading pollen around your home — and when possible, bathe them once a week," Carver said. Similar to changing your clothes upon returning home, it's a wise idea to avoid drying your laundry outside during hay fever season. In much the same way as pollen can attach to your clothing when out, it is the same if you dry your laundry outside. You are leaving your clothes prone to that transmission, which will then come into your home and into your wardrobe or cupboard. By drying your laundry indoors, whether that be on an airer or in a tumble dryer, you will be reducing the risk of bringing pollen into your home and contaminating other surfaces and/or clothes. "Like other small particles, pollen settles on surfaces and may become embedded in fabric, including carpet, curtains and bedding. It is important to regularly clean surfaces — wiping down hard surfaces with a damp cloth, vacuuming carpets and furniture fabric, and washing rugs and curtains," said Melanie Carver of AAFA. As we mentioned earlier, air purifiers are a great way to keep the air in your home allergen-free (or at least reduced). Air purifiers use HEPA filters to make sure this removal of allergens is effective, and some vacuum cleaners also use these filters to ensure effective removal. Hoovers with HEPA filters work by capturing microscopic particles, such as pollen, by trapping these particles within the filter. Vacuum cleaners without HEPA filters may not effectively trap these allergenic particles and instead release them back into the air. Therefore, we recommend using or investing in a vacuum cleaner that uses HEPA filters. "HEPA — high efficiency particulate air — filters on vacuums can be a useful tool in reducing pollen and other allergens from the home," said Melanie Carver. "Taking care to change your vacuum cleaner’s filters regularly helps ensure they operate most effectively to reduce allergens. Many vacuums, even those with HEPA filters, stir up a lot of debris into the air. People with sensitive airways should consider wearing a mask when vacuuming or have someone without asthma/allergies do the vacuuming, while the person with asthma/allergies stays out of the room for several hours until the dust settles. For some people, removing wall-to-wall carpeting may be a better solution." Melanie Carver also offered tips on what to look for in a vacuum if you are a hay fever sufferer. "When choosing a vacuum cleaner, look for the following," she said. "The vacuum must be proven to remove surface allergens, dust released when changing the vacuum bag or canister should remain low, exposure to allergens while changing the bag or cleaning the canister should be low, water-based collection systems must not negatively impact the relative humidity of the air and carpet and water-based collection systems must have a care code that emphasizes the importance of mold growth prevention in the collection system." The Miele Complete C3 is a powerful vacuum that uses HEPA filters to trap pollutants, including pollen. It has a sealed system, and with the HEPA filter, it can trap 99.99% of allergens, making this a great choice for hay fever sufferers. If you're after a cordless HEPA filter vacuum, the Dyson V15 is a good option. A cordless vacuum can make it easy and quick to nip around, which may be especially beneficial to those with hay fever. Plus, this Dyson has a washable filter and has been engineered with pets in mind — another member of the family who may bring pollen inside.

Record Groundnut Production Achieved with Tushar Irrigation Technology

Record Groundnut Production Achieved with Tushar Irrigation Technology

Bhojram Tijare A progressive agriculturist from Mundhari Buj in Mohadi taluka of Bhandara district, Bijay Mohanrao Bhoyar has achieved a record production of groundnut with the help of Tushar irrigation technology, which has made the dream of low water, low seeds and high yield at low cost a reality. The crop produced in just 20 days using only 90 kg of seeds in three acres of land has broken the old record and has yielded a total of 41 quintals of groundnut. This success story has been inspirational for other farmers. The water and fertilizers used in the cultivation using Tushar irrigation technology have been used at the right time and in the right quantity.

Police Use Technology to Recover Stolen Gold Chain in Record Time

Police Use Technology to Recover Stolen Gold Chain in Record Time

Since the identity of the woman was not known, the police cleverly checked the transactions of the scanner at the banana seller. The bank account details of the transaction at that time were extracted. It turned out that the woman was from Rajgurunagar (T. Khed). When the police contacted her immediately, she honestly confessed to having found the chain and handed it over to the police. The police then returned the gold chain to Parameshwar Pawar's wife. This quick and technical investigation by the police brought great relief to the Pawar family as the lost chain was found within a few hours. Modern technology was effectively used along with the traditional investigation in this entire operation.

India's Diabetes Burden: Obesity Drives Heart Failure Risk

India's Diabetes Burden: Obesity Drives Heart Failure Risk

India's diabetes burden has risen markedly, with 101 million individuals living with diabetes. The clinical burden is compounded by heart failure (HF), affecting nearly 50% of individuals with T2D in India. The interplay of multiple modifiable comorbidities, including obesity, CAD, hypertension, etc., further amplifies the complexity of managing HF in T2DM patients 2 . T2DM patients carry a 2–5 times higher cardiovascular risk, with more than 50% of deaths attributable to CVD. Progressive HbA1c increases are accompanied by increases in HF risk — yet BMI outperforms HbA1c in predicting HF episodes. Each 1 kg/m² BMI increase raises HF risk by 5–7%, while each 5-unit BMI increase is associated with a 41% higher HF risk. Interestingly, in the absence of adiposity, diabetes alone was not consistently associated with HFpEF — confirming obesity as the dominant driver of HF risk in T2DM, with obese T2D-HFpEF patients facing greater exercise intolerance, more HF hospitalisations, and worse prognosis 3,4 . T2D promotes heart failure through two divergent pathways. Hyperglycemia drives maladaptive signaling via the hexosamine, polyol, and pentose phosphate pathways, alongside advanced glycation end products. More critically, visceral adiposity causes adipokine imbalance, cardiac steatosis, and pericardial constraint — emerging as the predominant mechanistic driver of diabetes-associated HF. (Figure 1)4 Figure 1: Visceral Adiposity & Hyperglycemia: Interactions Driving Development and Progression of Heart Failure Evidence from the Look AHEAD trial sub-analysis demonstrated that a 10% BMI decrease over 1-year and 4-year periods was independently associated with 31% and 20% reductions in incident heart failure (HF), respectively, among overweight/obese adults with T2DM 5 . Similarly, in the SELECT trial, subcutaneous semaglutide injections-mediated 8.5% weight loss yielded an 18% reduction in the HF composite endpoint (HR: 0.82; 95% CI: 0.71–0.96) 6 . Retrospective bariatric surgery data further support these findings, with Roux-en-Y gastric bypass achieving a 62% reduction in incident HF (HR: 0.38; 95% CI: 0.22–0.64) following a mean 30% BMI decrease at 5 years 7 . The ICMR Standard Treatment Workflow (STW) for Heart Failure (January 2026) favored and suggested weight reduction at all levels of care settings (across PHC, CHC, district hospital, and tertiary care settings) in HF patients 8 . Aligning with this, the Consensus Statement from the Heart Failure Society of America (HFSA) Scientific Statements Committee also recommends at least 5%–10% weight loss for patients with heart failure and BMI ≥35 kg/m2 9 . The Heart Failure Association of India (HFAI) guidelines for Diagnosis and Management of Heart Failure (2025) also recommended that weight reduction strategies should be advised to HF patients. Further, the guideline cited that semaglutide, which reduced obesity in the SELECT trial, also reduced heart failure hospitalizations 10 . The ACC in their 2025 Scientific Statement on "Management of Obesity in Adults with Heart Failure" noted that among GLP-1 receptor agonists, injectable semaglutide has shown improvements in symptoms, functional capacity, quality of life, and weight reduction in patients with HFpEF and obesity, based on trials enrolling individuals with BMI ≥30 kg/m² 11 . NICE NG28 (February 2026) also recommends subcutaneous semaglutide as first-line triple therapy alongside metformin and an SGLT2 inhibitor in T2D patients with established atherosclerotic cardiovascular disease 12 . As access to GLP-1 RAs grows in India, injectable semaglutide is expected to significantly advance the management of patients with T2D and heart failure. Beyond glycaemic control, subcutaneous semaglutide reduces CV death, HF and non-fatal MI by 20% (SELECT; HR 0.80), lowers NT-proBNP levels, and delivers sustained weight reduction — collectively addressing the obesity–inflammation–cardiac remodeling axis – the pathophysiologic triangle driving HF progression in T2DM. ●India's 101 million T2DM patients face a compounding HF burden; affecting nearly 50% of individuals with T2D — with obesity emerging as the dominant driver. ●Visceral adiposity drives HF through adipokine imbalance, cardiac steatosis, and pericardial constraint — with hyperglycaemia further amplifying maladaptive cardiac signaling via advanced glycation end products and hexosamine pathway activation. ●Evidence confirms a proportional cardiometabolic benefit — 10% BMI reduction reducing incident HF by 31%, semaglutide-mediated 8.5% weight loss yielding 18% reduction in HF composite endpoint, and bariatric surgery achieving 62% reduction in incident HF. ●ICMR STW 2026, HFSA, HFAI 2025, and ACC 2025 suggest weight-targeted therapy among cornerstone interventions for HF management in obese T2DM patients. ●As GLP-1 RA access broadens in India, injectable semaglutide-based treatment will herald a transformative era in T2D-HF management.

A "potentially hazardous" asteroid contains all of the "letters" that make up DNA, suggesting that these key ingredients for life may be common in the solar system . Researchers made the discovery after analyzing samples collected from asteroid Ryugu, a 3,000-foot-wide (900 meters) space rock shaped like a spinning top. The scientists detected a complete set of canonical nucleobases, which are the building blocks for DNA — the genetic foundation for all life on Earth — and its lesser-known cousin RNA , according to a new study published Monday (March 16) in the journal Nature Astronomy . This "does not mean that life existed on Ryugu," study lead author Toshiki Koga , a biogeochemist at the Japan Agency for Marine-Earth Science and Technology, told AFP, per Phys.org . "Instead, their presence indicates that primitive asteroids could produce and preserve molecules that are important for the chemistry related to the origin of life." This isn't the first time an asteroid has been found to be carrying all five nucleobases. NASA recovered the same set of nucleobases from asteroid Bennu in 2023, courtesy of the OSIRIS-REx spacecraft . Researchers have also detected the nucleobases on meteorites . Taken together, these findings suggest that nucleobases could be widespread in the solar system. Scientists aren't sure how life got started on Earth. Some theories posit that it originated here, such as in deep-sea vents. However, there's also a possibility that life — or the building blocks of life — didn't form on Earth at all but were carried here on comets or asteroids. César Menor Salván , an astrobiologist at the University of Alcalá in Spain who was not involved in the study, emphasized in an interview with AFP that the new results "do not suggest that the origin of life took place in space." Get the world’s most fascinating discoveries delivered straight to your inbox. However, "with this and the results from Bennu, we have a very clear idea of which organic materials can form under prebiotic conditions anywhere in the universe," Salván added. The Japan Aerospace Exploration Agency (JAXA) collected the Ryugu samples as part of its Hayabusa2 mission, which launched in 2014. The uncrewed Hayabusa2 spacecraft landed on the asteroid in 2019, before collecting two dust samples from the asteroid's surface and returning them to Earth in 2020. The samples weigh just 5.4 grams (0.19 ounces) each, less than the weight of a quarter, but have excited scientists for years. Preliminary analysis of a tiny fraction of the sampled material in 2023 revealed that the asteroid contained many of the building blocks for life , including one nucleobase (uracil) and numerous other organic materials, including 15 amino acids, which are the foundation of proteins. These are prebiotic molecules, and although they're not life, they're found in all life. One study also revealed microorganisms crawling all over one asteroid Ryugu sample . But these microorganisms closely matched Earth's bacteria, and their presence was almost certainly the result of contamination after the sample returned to Earth. (Even NASA has had trouble keeping Earth bacteria off its interplanetary spacecraft in ostensibly sterile rooms). For the new study, researchers did a much more comprehensive analysis of nucleobases than was done during the preliminary research, using more sample material and optimized analytical techniques. This time, the researchers found all of the nucleobases — adenine, guanine, cytosine, thymine and uracil. These natural compounds mix with ribose and phosphate to form DNA and RNA. The researchers also looked at the ratio of nucleobases and compared them to those discovered on Bennu and on two meteorites (Murchison and Orgueil) that had fallen to Earth. Nucleobases are split into two groups based on their chemical structure. Adenine and guanine are purines, which are known for their double-ring structure, while cytosine, thymine and uracil belong to the single-ring-structured pyrimidines. The researchers found that Ryugu had equal amounts of purines and pyrimidines, while Bennu and Orgueil were more enriched in pyrimidines and Murchison was more enriched in purines. Notably, the researchers also identified a strong correlation between the purine-pyrimidine ratio and the concentrations of ammonia in Ryugu, Bennu and Orgueil, suggesting that ammonia, another life-friendly molecule , may have been a key factor driving similar nucleobase formation pathways in the rocks' distinct environments, according to the study. "Because no known formation mechanism predicts such a relationship, this finding may point to a previously unrecognized pathway for nucleobase formation in early solar system materials," Koga said. — 'City killer' asteroid will narrowly miss the moon, James Webb Telescope reveals — 'Potentially hazardous' asteroid 2024 YR4 was Earth's first real-life planetary defense test — Astronomers discover skyscraper-size asteroid hidden in sun's glare — and it's moving at a near-record pace Ryugu and Bennu are a common type of asteroid known as carbonaceous asteroids, which make up 75% of all asteroids in our solar system. James Webb Space Telescope (JWST) observations suggest that both asteroids may originate from the same parent asteroid that broke apart billions of years ago. The Orgueil meteorite also derived from a carbonaceous asteroid. These ancient rocks are left over from when the solar system was still forming around 4.5 billion years ago, when the Earth was also forming. The detection of nucleobases, therefore, suggests that carbonaceous asteroids may have helped Earth get its life-forming chemicals. "The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the prebiotic chemical inventory of early Earth," the researchers wrote in the study.
