Initially, this blob moved at about 300 kilometers per second but rapidly accelerated to 1,500 kilometers per second-a speed fast enough to circle the Earth in just 30 seconds.This rare footage shows the eruption and the plasma's journey across SUIT's field of view, with the Sun's brightness reduced in the video to highlight these dramatic off-limb structures.Solar flares are powerful bursts of energy caused by the sudden release of magnetic energy in the Sun's atmosphere. These events can send huge amounts of radiation and energetic particles into space, sometimes disrupting radio communications, damaging satellites, and even affecting power grids on Earth. advertisementUnderstanding these flares is crucial for protecting our technology and infrastructure.Traditionally, solar flares have been studied mostly in X-rays and extreme-ultraviolet light. However, SUIT's observations in the near-ultraviolet are unique, providing scientists with new data about the lower layers of the Sun's atmosphere-the photosphere and chromosphere-using 11 specially designed filters.This helps researchers track how energy moves through the Sun's atmosphere and how flares impact space weather.The Aditya-L1 spacecraft was launched in September 2023 and reached its observation point, the Lagrange Point L1, in January 2024. From this stable position, about 1.5 million kilometers from Earth, it can continuously monitor the Sun without interruption.The December 31 observation was made during the spacecraft's journey to L1, catching an X-class flare and a fast-moving coronal mass ejection (CME) from active region NOAA 13536.By combining SUIT's ultraviolet images with data from other international observatories, scientists can better understand the origins of solar flares and their effects on Earth, marking a major step forward in solar research.

Axiom-4 boost for Isro's manned spaceflight plans
The recent Axiom-4 mission, featuring group captain Shubhanshu Shukla of the Indian Air Force as pilot, is far more than a symbolic gesture for India. It represents an important and strategic stepping stone for the Indian Space Research Organisation (Isro)'s ambitious Gaganyaan manned spaceflight programme. It is also a firm indication that India is now ready to move onto a more mature space programme. the Axiom-4 mission strengthens international collaboration and knowledge transfer for the Indian community, elevating India's standing as a serious and capable player in the exclusive club of human spacefaring nations. (ANI Video Grab) The Axiom-4 mission allows Isro to bridge the gap between extensive ground-based training and invaluable real-world experience, which is critical to the plans to send Indian gaganyatris into orbit. Over the last few decades, Isro has emerged as a global leader in cost-effective satellite launches and interplanetary missions, from the iconic Chandrayaan series to the Mars Orbiter Mission. However, human spaceflight has its own unique set of challenges. It requires extreme levels of safety and reliability and a focus on the needs and limitations of the human body. This is where, most importantly, Axiom-4 provides an unparalleled opportunity for practical in-space training and exposure. Shukla is part of the first batch of gaganyatris already selected by Isro. His role as pilot in the Axiom-4 flight means he has gained firsthand experience in critical aspects of human spaceflight: living and working in almost-zero gravity, handling complex spacecraft systems, responding to contingencies, and performing intricate docking procedures at the International Space Station (ISS). This 'lived experience' on a fully operational platform with a consortium of international partners is something no simulated activity can fully replicate. The physiological adaptations to sustained microgravity, the mental aspects of confinement and ISS life, the long hours of exercise and muscle toning, the complex teamwork with a truly international crew and the nuances of real-time flight dynamics, are lessons that will be directly fed back into Gaganyaan's astronaut-training modules and mission protocols. Shukla's experience in pre-launch quarantine, spacecraft ingress and egress, medical diagnostics in microgravity, and health readiness will be invaluable in the planning for Indian missions. Moreover, the major sustained activities on this mission involves critical scientific experiments with direct relevance to Gaganyaan. India's contribution to the Axiom-4 science involves biological and genetic research payloads, developed by Isro in collaboration with leading Indian institutions. These include cultivating food crops such as moong and methi sprouts, and examining strains of cyanobacteria and microalgae to study their growth rates, cellular responses, and biochemical activity in microgravity. There is research on muscle regeneration under microgravity to identify skeletal muscle dysfunction and explore therapeutic strategies. There is a close study of the functioning of tardigrades, which are among the most resilient forms of life. Finally, there are studies of the physical and cognitive impact of using devices in microgravity to inform future spacecraft computer design. These experiments are not merely academic, they are designed to address the very challenges Gaganyaan will face — ensuring sustainable food and oxygen, maintaining astronaut health, and understanding long-duration effects of space life on humans. The data gathered from these experiments will be invaluable for refining Gaganyaan's environmental control and life support systems, crew health management protocols, and overall mission design. Furthermore, the Axiom-4 mission strengthens international collaboration and knowledge transfer for the Indian community. Working alongside not just public sector partners such as the US's National Aeronautics and Space Administration (Nasa), but also private players such as Axiom Space — which will soon operate an independent space station — provides Isro with unique insights into global best practices in human spaceflight operations, safety standards, and mission management. This kind of equal partnership on a global stage also elevates India's standing as a serious and capable player in the exclusive club of human spacefaring nations, rekindling the legacy of the first move in 1984 with cosmonaut wing commander Rakesh Sharma. The next crucial phases for Gaganyaan include conducting a series of uncrewed test flights, designed to rigorously test various Gaganyaan systems, including the Crew Escape System, the Crew Module's re-entry and recovery, and the performance of the human-rated LVM3 launch vehicle. These are important for proving the safety and reliability of the entire system. One of these will carry Vyommitra, Isro's humanoid robot, to evaluate the integrated systems and environment in the crew module for suitability for human occupants. Also being developed for Gaganyaan is the systematic and careful process of integrating the crew module, which will house the astronauts, with the service module, providing essential services like propulsion, power, and life support, is ongoing. This includes fine-tuning the human-machine interfaces and ergonomic demands based on real-world insights, which will incorporate what is learnt from the Axiom-4 mission. As Shukla gains invaluable experience on Axiom-4, the other astronaut-designates continue their rigorous training, including simulations of all mission phases, parabolic flights for microgravity exposure, water survival training, and extensive medical and psychological conditioning. The culmination of these efforts will be the maiden crewed Gaganyaan mission. This aims to send three Indian astronauts to a low Earth orbit (approximately 400 km), or LEO, for a duration of several days, before a safe splashdown in the Arabian Sea. This is currently targeted for the first quarter of 2027. Beyond Gaganyaan, India's next ambition is the assembly of our own space station, the Bharatiya Antariksh Station, by 2035. The first module is expected to launch by 2028, with the full station becoming operational by 2035. This long-term vision will provide a sustained platform for scientific research, technological development, and further LEO training of Indian astronauts. India also aims to have a crewed lunar mission in 2040. Meanwhile, Shukla and colleagues will return to Earth in the second week of July. What next? Shukla's thesis advisor at the Indian Institute of Science (IISc) in Bengaluru has publicly appealed that he should come back to IISc and finish his Masters' dissertation as soon as he can. Somak Raychaudhury is vice-chancellor and professor of physics, Ashoka University. The views expressed are personal.

NASA alert! 120-foot airplane-sized asteroid 2025 MM to make closest flyby on Earth today; should we be concerned
Asteroid 2025 MM: Star gazers and astronomers are pointing to an airplane-sized asteroid 2025 MM , which will have a close but safe flyby of Earth this week. Notwithstanding its closeness, authorities assure us that there is no threat to our planet Earth. Tired of too many ads? go ad free now Moving at high velocity and on a well-tracked path, the asteroid will fly by at a comfortable distance. Events like these offer a reminder of space's unpredictable nature and the importance of ongoing sky surveillance. While 2025 MM poses no immediate threat, its flyby underscores the need for scientific vigilance in tracking objects that share our celestial neighbourhood. Asteroid 2025 MM to make closest approach on July 01, 2025: Speed and distance The asteroid is forecast to reach its nearest point to Earth on July 1, traveling at a distance of about 1.29 million kilometers (about 800,000 miles). Although this is close in cosmic terms, it's over three times farther away from Earth than the Moon is. Asteroid 2025 MM is traveling at a speed of approximately 23,874 miles per hour (38,428 kilometers per hour). Traveling this speed, it would take under two hours to orbit Earth if it were in a state of orbit. This is normal for near-Earth objects, which are drawn into the Sun's gravity and orbital dynamics as they move about the inner solar system. Its high velocity and regular path made it simpler for space agencies to simulate its orbit and ensure that it would safely pass by our planet. How large is asteroid 2025 MM Asteroid 2025 MM is approximately 120 feet (36 meters) in diameter—similar to the wingspan of a Boeing 737 plane. While fairly small in cosmic perspective, it's large enough to be seriously considered by planetary defense specialists. Asteroids of this magnitude can do tremendous harm if they come into Earth's atmosphere or collide with the planet's surface. Tired of too many ads? go ad free now Yet with 2025 MM, it will pass safely by, providing experts with an opportunity to observe it without risk. Why Aten asteroids like 2025 MM are important to scientists 2025 MM is part of the Aten family of asteroids, which are known to have orbits that are generally within Earth's orbit around the Sun. The orbits of these asteroids normally cross Earth's orbit and hence are very significant to track. Though Aten asteroids are normally seen close to Earth, not all of them are hazardous. NASA actually has a set of parameters by which they check if an asteroid is even likely to be hazardous. Asteroid 2025 MM: Is it considered dangerous NASA has confirmed that asteroid 2025 MM is not classified as a 'Potentially Hazardous Object' (PHO). According to NASA's Planetary Defense Coordination Office, an asteroid must be: Larger than 150 meters (492 feet) in diameter, and Come within 7.4 million kilometers (4.6 million miles) of Earth to qualify as potentially hazardous. With its smaller size (120 feet) and more distant path, 2025 MM doesn't come anywhere close to either threshold. Yet it serves as a reminder that even small space rocks are worth closely monitoring, particularly since even minor changes in orbit could potentially present future hazards. Why scientists are still keeping an eye on it While 2025 MM will not strike Earth, scientists still track it using powerful telescopes and radar. This is owing to the fact that asteroid paths can alter over time as a result of numerous influences: Solar radiation inducing slow drift (referred to as the Yarkovsky effect) Collision or fragmentation occurrences within the asteroid belt Even a small deviation in path would lead to an asteroid coming in closer in a subsequent orbit. That is why continuous monitoring and path forecasting models are essential in planetary defense operations. Asteroid 2025 MM highlights the need for constant vigilance While asteroid 2025 MM will pass safely by Earth, its visit is a sobering reminder of the dynamic and capricious nature of space. Our solar system is teeming with millions of asteroids and comets, several of which make their way across our planet's path without us even realizing it. Asteroid 2025 MM poses no near-term threat, but it does underscore the absolute necessity of careful skygazing and scientific foresight. The heavens are full of marvels—and sometimes, possible threats—and being at the head of the curve may one day prove to be the difference between life and death. Also Read |

Shubhanshu Shukla on how he feels aboard the International Space Station: ‘Thoda sa sarr bhaari hai…'
Indian Space Research Organisation (ISRO) astronaut and Group Captain Shubhanshu Shukla, currently aboard the International Space Station (ISS) as part of the Axiom Mission 4 (Ax-4), recently shared his first reaction on reaching ISS. In a video message on the Axiom 4 YouTube channel, he said, 'This is a small message for my fellow countrymen. I have been able to come to the International Space Station with your love and blessings. It looks very easy to stand here, but it's quite difficult. Thoda sa sarr bhaari hai, thodi takleef ho rahi hai par yeh sab bahut choti cheezein hai (I feel a little headache, lightheadedness, discomfort, but these are small issues). In a few days, we will get used to this. This is the first phase of this journey. We will conduct science experiments and continue to communicate with you over the next 14 days. It's a big milestone in our space journey. It will be exciting.' Shukla also opened up about not feeling well in his first call from space, 'I was not feeling well, and I was very sleepy when we were launched into the vacuum. Learning how to walk and eat in space like a child.' Taking a cue from his admission, let's explore the bodily changes that astronauts experience in space. Experts suggest that his candid admission reflects the common physiological responses the human body experiences upon entering microgravity. When in space, the human body can experience many changes due to the lack of gravity, said Dr. Manjusha Agarwal, senior consultant in internal medicine at Gleneagles Hospital Parel, Mumbai. 'One of the first effects astronauts feel can be the fluid shift as the fluids move upward toward the head, making it feel heavy, causing puffy faces, nasal congestion, and pressure in the skull. Hence, it can cause dizziness, headaches, and a sense of imbalance,' Dr Agarwal said. The inner ear, which controls balance, becomes confused without gravity, causing 'some astronauts feel motion sickness in the first few days.' 'Other issues can also occur. Muscles and bones weaken over time because they aren't used the same way as on Earth. The heart works less hard in space, which can lead to a drop in blood pressure,' said Dr Agarwal, adding that vision problems can occur due to pressure on the eyes. Such symptoms are part of what's known as Space Adaptation Syndrome (SAS)—a condition many astronauts face in the initial hours or days aboard the International Space Station, said Dr Hiran S. Reddy, consultant physician, diabetologist, and critical care specialist, Gleneagles Hospital, Lakdi ka Pul, Hyderabad. While these symptoms are typically mild and temporary, they indicate the body's effort to recalibrate itself to a weightless environment, noted Dr Reddy. 'Medical teams monitor these early signs closely to ensure there is no escalation into more serious issues such as vision changes or prolonged intracranial pressure,' said Dr Reddy. However, understand that not everybody can experience the same problems. 'Some may not experience any problems at all. Hence, to manage these symptoms, astronauts follow strict exercise routines, maintain a healthy diet, stay hydrated, and undergo regular medical checks to keep their bodies fit during space travel,' said Dr Agarwal.
