World's largest digital camera unveils stunning images of the universe
One striking photo captures the Trifid and Lagoon Nebulae in a star-forming region of the Milky Way. Created from 678 monochrome exposures using four different filters, the image reveals rich, vivid detail in just over seven hours of observation.
Another highlight was a video revealing a swarm of previously unknown asteroids—2,104 newly discovered space rocks, including seven near-Earth asteroids that pose no threat.
In a single wide-field image, the Rubin Observatory's telescope simultaneously spotted asteroids within our solar system and galaxies billions of light-years away, demonstrating its extraordinary reach. Perched atop Cerro Pachón in Chile's Andes Mountains, the $810 million US-led project is designed to scan the entire southern sky every 3–4 nights—vastly faster than space telescopes like Hubble or James Webb, which focus on small sections with greater detail.
The newly released images are not research data, but a visual showcase of the observatory's capabilities. 'We go into astronomy because we like to look at the sky — and at the beauty of it,' said Sandrine Thomas, deputy director of construction, based in Tucson, Arizona.
These first glimpses hint at the scientific breakthroughs to come—and remind us of the awe that first draws us to the stars.

‘Feitian 2': What we know about China's new hypersonic craft and why it matters
China successfully tested its new hypersonic craft 'Feitian 2' at a site in the northwest of the country. Experts have expressed concern at the development and the pace at which Beijing's hypersonic missile programme is evolving. But what do we know about it? read more China has a new hypersonic craft nicknamed the 'Feitian 2'. AP China has a new hypersonic craft. The craft named 'Feitian 2' was successfully tested at a site in northwest China. Experts have expressed concern at the development and the pace at which Beijing's hypersonic missile programme is evolving. But what do we know about the 'Feitian 2'? Why does it matter? Let's take a closer look: What we know The 'Feitian 2' was developed by scientists at the Northwestern Polytechnical University (NPU). It is an experimental, reusable vehicle. The Shaanxi Province Aerospace and Astronautics Propulsion Research Institute also participated in the project. The craft is said to have reached speeds of up to Mach 12 (14,800 kmph). STORY CONTINUES BELOW THIS AD The NPU-led team said the development marked the first time real-flight data has been collected for a rocket-based combined cycle (RBCC) engine using a kerosene-hydrogen peroxide propellant. The team said the test flight demonstrated the 'Feitian 2's' capabilities to transition between various flight modes. This included toggling between ejector mode at take off It also demonstrated key capabilities including variable-geometry intake operation, thrust-varying acceleration and autonomous flight with variable angle of attack. The Chinese researchers have claimed that this allows the craft to change its inner structure during the operation as well as autonomously change its trajectory and angle if needed. The 'Feitian 2' was developed by scientists at the Northwestern Polytechnical University (NPU). Image courtesy: X The test comes three years after the 'Feitian 1' had a test flight in July 2022. The 'Feitian 2'has larger tail fins compared to its predecessor. It also has wings near its rocket head. This helps the craft better stabilise and control itself. Why it matters Hypersonic missiles usually use liquid oxygen combined with kerosene or liquid hydrogen as propellants. The 'Feitian 1' showed kerosene can be used as fuel for the propulsion system. Meanwhile, the 'Feitian 2' used a kerosene and hydrogen peroxide propellant. This allows it to get rid of complex cryogenic systems needed. It essentially combines a traditional rocket engine with that of a ramjet – which relies on oxygen. STORY CONTINUES BELOW THIS AD This may sound simple, but it is in fact a ground-breaking achievement. The 'Feitian 2' does this because its RBCC engine, unlike those of normal hypersonic missiles which used liquid oxygen, is designed to use atmospheric oxygen. It thus massively brings down the weight of the oxidiser – which is needed at high altitudes or in thin atmosphere – used during the flight. This in turn increases the craft's possible payload as well as its fuel efficiency. It also gets rid off the need for a heavy cooling system. Achieving smooth transitions between different flight modes has thus far been a problem for hypersonic missiles and crafts. However, it seems that the NPU-led team has solved this problem, which is a massive scientific achievement. The test also showed that the vehicle was capable of autonomous flight. The researchers say that the successful test flight of the 'Feitian 2' will aid the future development of supersonic crafts and missiles. They say this could result in reusable military drones, hypersonic reconnaissance crafts and even civilian transport ships. STORY CONTINUES BELOW THIS AD It also puts China ahead of its competitors including the US and Russia in the field of hypersonic missile tech. Beijing already has a number of hypersonic missiles including the DF-100, Starry Sky-2, YJ-21 and Lingyun-1. China also has developed a number of hypersonic glide vehicles including the DF-ZF, which is paired with the DF-17 ballistic missile. This achievement comes even as the NPU remains under US sanctions. Undergraduate students from NPU also have a tough time obtaining US visas. US experts have expressed concern at the development, saying that China has basically used research done in the US as a springboard to leap ahead. With inputs from agencies

Muscles, Microbes, And Microgravity: India's First Biology Experiments In Space
New Delhi: India has taken its first bold steps into space biology with a series of pioneering experiments aboard the International Space Station (ISS), as part of the Axiom-4 mission-referred to by some as Mission Akash Ganga. These experiments, conducted by Group Captain Shubhanshu Shukla, mark a significant milestone in India's scientific and technological journey, exploring how biological systems behave in microgravity and radiation-rich environments. At the heart of this initiative is the Department of Biotechnology (DBT), under the leadership of Dr Rajesh Gokhale, Secretary of DBT. In an exclusive conversation with NDTV, Dr Gokhale described the mission as a "floating lab in space" that will help India understand biological adaptability in ways never tested before. The experiments are designed to explore fundamental questions about human health, sustainability, and bio-manufacturing in space. Muscle Stem Cell Regeneration In Microgravity One of the flagship experiments led by DBT focuses on skeletal muscle stem cells. Conducted by the Institute for Stem Cell Science and Regenerative Medicine (InStem) in Bengaluru, this study investigates how microgravity affects the regeneration of muscle tissue. In space, the absence of gravitational force leads to muscle and bone mass reduction, a phenomenon well-documented in astronauts. Dr Gokhale explained that the experiment will compare muscle stem cell behaviour in space with those grown under Earth conditions. The goal is to understand whether the regenerative capacity of these cells is compromised in microgravity. This research could have far-reaching implications - not only for astronaut health during long-duration missions but also for treating age-related muscle degeneration and diseases like muscular dystrophy on Earth. The experiment explores the role of mitochondria - the powerhouse of the cell - in maintaining muscle health. Mitochondrial dysfunction is a known contributor to muscle loss. DBT scientists are testing two compounds: dihydrofolate and a thiol-containing amino acid, both known to enhance mitochondrial function. By supplementing these chemicals in space-grown muscle cells, researchers aim to determine whether mitochondrial regeneration can be achieved in microgravity. If successful, this could lead to new therapeutic strategies for muscle recovery in space and on Earth, particularly for conditions like sarcopenia and cachexia. Edible Microalgae Cultivation One DBT-led experiment involves growing edible microalgae in space. Conducted by the International Centre for Genetic Engineering and Biotechnology (ICGEB) in Delhi, this study examines how three species of microalgae adapt to space conditions. These algae are photosynthetic organisms that absorb carbon dioxide and release oxygen - making them ideal candidates for life support systems in space. Dr Gokhale emphasised the dual benefits of this experiment: oxygen generation and food production. Microalgae could serve as bio-regenerators in future missions like Gaganyaan, replacing traditional chemical-based systems like zeolites. Their ability to grow continuously and be consumed makes them a sustainable solution for long-term space habitation. Cyanobacteria For Nutrient Recycling Another innovative experiment focuses on cyanobacteria, known for their ability to recycle nutrients. Human urine, rich in urea and nitrogen, presents a challenge in closed-loop space environments. This study investigates how cyanobacteria assimilate nitrogen from both organic (urea) and inorganic (nitrate) sources. The aim is to convert waste into usable resources-a concept Dr Gokhale described as "waste to wealth in space". Understanding how these bacteria function in microgravity could lead to efficient nutrient recycling systems for future space stations and planetary habitats. Seed Sprouting And Crop Growth India is also conducting experiments on seed sprouting, involving crops like fenugreek (methi) and moong or green gram. These seeds are being grown in space to observe changes in growth patterns and microbial interactions. Although the sprouted seeds will not be consumed by Mr Shukla, they will be returned to Earth for detailed analysis. This experiment is part of a broader effort to understand how Indian crop varieties respond to space conditions. It could pave the way for space farming and food security in extra-terrestrial environments. Eye Function And Screen Exposure While not directly under DBT, another experiment examines how prolonged exposure to screens affects eye function in space. Vision problems have been reported among astronauts, and this study aims to understand the physiological changes that occur in microgravity. It adds a critical dimension to astronaut health research. Water Bears (Tardigrades) Reproduction A particularly intriguing experiment involves tardigrades, microscopic organisms known for their resilience. Researchers are studying their reproductive cycle in space, specifically whether they can lay and hatch eggs under microgravity conditions. This could offer insights into how complex biological processes like reproduction are affected by space environments. Seeds For Genetic Analysis India is also sending seeds of various crop varieties to space, not for growth but for genetic analysis upon return. This experiment, though previously conducted by other nations, carries an Indian signature and aims to understand how space exposure affects genetic traits. Implications For Bio-Manufacturing And Policy These experiments align with India's Bio-E3 policy - Biotechnology for Economy, Environment, and Employment - approved by the Cabinet and championed by Prime Minister Narendra Modi. Dr Gokhale highlighted that DBT's collaboration with ISRO is part of a long-term roadmap extending to 2040. The insights gained from these studies could revolutionise bio-manufacturing, especially in areas like carbon dioxide fixation and metabolic engineering. For example, algae used in space could be adapted to trap industrial emissions on Earth, offering sustainable solutions to climate challenges. A Vision For Viksit Bharat Dr Gokhale emphasised the transformative potential of cross-disciplinary science. From sports medicine to space biology, DBT is expanding its horizons to contribute to Viksit Bharat - a developed India. The department's pioneering role in biotechnology, from GM mustard to COVID vaccines, now extends to the final frontier, space. As India steps into the realm of space biology, these "baby steps" could soon become giant leaps, shaping the future of human health, sustainability, and innovation both in orbit and on Earth. India has big ambitions in space, from launching an Indian to space in 2027, having a space station by 2035 and landing an Indian on the moon by 2040. Group Captain Shukla has in fact laid the first firm footsteps for India's ambitious human space flight mission.
