NASA observes brightest black hole blasts since the Big Bang

NASA, along with the European Space Agency (ESA) and several ground-based observatories, has detected some of the most powerful space explosions ever recorded. These dramatic events happened when giant black holes tore apart massive stars. The explosions were so intense that they released more energy than 100 supernovae, which are already among the brightest events in space. These rare outbursts, known as " extreme nuclear transients ," revealed black holes that were previously hidden in distant galaxies. One such explosion, nicknamed 'Barbie,' was one of three spotted by astronomers. These powerful flashes of light lasted for months and are giving scientists new insight into how black holes behave and how they help shape the galaxies around them. They may even help us detect black holes that existed over 12 billion years ago, closer to the beginning of the universe. NASA captures black holes exposed by devouring stars Most black holes are invisible because they don't emit light unless they are actively feeding. However, when a star gets too close to a black hole, it gets pulled in and shredded apart. This violent process, called a tidal disruption event, causes the black hole to light up with a bright flash of energy across many wavelengths, including ultraviolet light, X-rays, and infrared. Using data from NASA's Swift Observatory, ESA's Gaia mission, WISE/NEOWISE, and many Earth-based telescopes, scientists captured these rare events. The black holes involved in these cases swallowed stars that were three to ten times bigger than our Sun. The energy from these events built up over more than 100 days and then slowly faded over the next 150 days. The 'Barbie' event was first noticed in 2020 by the Zwicky Transient Facility, a sky survey project in California. Two similar explosions were recorded by Gaia in 2016 and 2018. NASA's Swift telescope helped confirm that these were black holes tearing stars apart, and not just exploding stars or other kinds of space activity. The radiation from these events also lit up the dusty areas around the black holes, giving scientists a closer look at the environments where these giants live. A new way to discover ancient black holes These extreme nuclear transients are giving astronomers a new tool to find supermassive black holes that are otherwise invisible, especially in the early universe. Scientists believe that 90 percent of black holes from that time are inactive, meaning they don't consume anything and stay completely dark. But if one of those ancient black holes rips apart a star, it briefly becomes visible. As the universe expands, the light from these old explosions stretches into infrared light, which is harder to see with regular telescopes. Fortunately, NASA's upcoming Nancy Grace Roman Space Telescope, planned to launch by 2027, is designed to detect this kind of stretched infrared light. With its powerful sensors and wide view of the sky, it could spot these rare events from as far back as 12 billion years ago, when the universe was only about 10 percent as old as it is today. This research was supported by NASA's FINESST grant program and the Hubble Fellowship. According to lead author Jason Hinkle, these findings give astronomers a roadmap for finding more hidden black holes and understanding how they grow and influence the universe over billions of years.

India's Shubhanshu Shukla working on experiment to power Gaganyaan Mission

India's first astronaut on the International Space Station, Group Captain Shubhanshu Shukla, is working on the space microalgae experiment sent by the Indian Space Research Organisation (ISRO).Shux deployed sample bags and captured images of the algae strains. These tiny organisms could play a big role in the future of space exploration, offering a sustainable, nutrient-rich food source for long-duration are potentially useful organisms for future spaceflight that could be used as foods, fuel, or even in life support systems. In this experiment, three strains of microalgae will be grown, and the impact of microgravity on the growth, metabolism, and genetic activity will be investigated versus algae grown on the ground. The results could provide Isro with new options to develop the critically needed life support system for the Gaganyaan Mission, the Indian human spaceflight Axiom crew, meanwhile, also collected data for the Neuro Motion VR project, where astronauts don VR headsets and perform attention-based tasks while their brain activity is monitored using functional near-infrared spectroscopy (fNIRS). This research explores how microgravity affects cognitive and motor functions, which could provide valuable insight for future deep space Commander Peggy Whitson is working on the Cancer in LEO investigation by capturing imaging samples that could unlock new insights into how cancer behaves under the unique stressors of microgravity. She also turned her lens toward creativity, photographing student hardware, science experiments, and artwork for the Saudi Space Agency's Microgravity of conducting the experiment, Shux spoke to Prime Minister Narendra Modi from the ISS and said that he was safe and doing fine aboard the Space Station, calling it a "whole new experience". He also said he was extremely glad to represent India in space. Shukla was launched on a SpaceX Dragon spacecraft from NASA's Kennedy Space Centre in Florida to the Space Station on Wednesday. The spacecraft completed a 28-hour journey before executing a flawless docking manoeuvre at the ISS's Harmony is joined by mission commander Peggy Whitson of the US, and mission specialists Sawosz Uznanski of Poland and Tibor Kapu of told PM Modi that he saw Earth as a complete planet with no borders visible and "it is our home".- EndsTune InMust Watch

Shubhanshu Shukla return date from ISS: When will the Indian astronaut come back?

Indian Air Force test pilot Group Captain Shubhanshu Shukla scripted history by becoming the first Indian to set foot on the International Space Station (ISS) after the docking of their spacecraft at the end of a 28-hour journey around the earth. Shukla, who is the second Indian to travel to space after Rakesh Sharma, reached the International Space Station on Thursday along with three other astronauts as part of the Axiom-4 mission for a 14-day stay during which the crew will be part of a series of science experiments. On reaching the ISS, Shukla and the other three astronauts were greeted with warm hugs and handshakes. 'With your love and blessings, I have reached the International Space Station. It looks easy to stand here, but my head is a little heavy, facing some difficulty; but these are minor issues,' he said in brief remarks in Hindi at the formal welcome ceremony at the ISS. 'I am astronaut 634. It is a privilege to be here,' he added. Shukla is scheduled to return to Earth on July 10, exactly 14 days after his arrival at the ISS. Before docking with the ISS, as the Dragon spacecraft circled the Earth, Shukla shared his early experiences in space. He said he was learning to live in microgravity 'like a baby' and described the feeling of floating in space as amazing. In his first message aboard the International Space Station, Shukla thanked the mission commander and said he feels 'privileged' to be here. 'Thank you Peggy (Whitson, the mission commander). I am number [Astronaut Number] 634, that's a privilege (laughs). But, to be fair, it is a privilege to be among the few who have got a chance to see the earth from a vantage point that I have been able to see now. 'It has been a wonderful ride. It has been great. I was looking forward to come to space. It is something to look forward to. But the minute I entered the International Space Station… this crew (points at the Expedition-73 crew already aboard the ISS) made me feel so welcome. You literally opened the doors to your house for us. It was fantastic. I feel even better. Shukla said that his head felt heavy upon reaching ISS but the tricolour on his shoulder reminded him that the Indians were with him. In an interaction with Prime Minister Narendra Modi from the ISS, Shukla said he was scheduled to conduct an experiment on the growth of microalgae, which are highly nutritious, in microgravity conditions. The astronaut also said he was studying whether specific supplements can delay muscle loss in microgravity conditions, which could help develop medicines for muscle degeneration in elderly people. The Prime Minister encouraged Shukla to carefully document all his observations, saying they would be of great value for India's future space missions. 'India must move forward with Mission Gaganyaan, build its own space station, and achieve the landing of an Indian astronaut on the Moon,' Modi said. In his message for the youth, Shukla said, 'The sky has never been the limit, not for me, not for you, and not for India.' He urged youngsters to hold onto this belief. Shukla's mission marks a major step in India's growing role in international space exploration and signals a new era for Indian astronauts on the global stage.
