A NASA astronaut aboard the International Space Station (ISS) has captured a stunning image of glowing red lights in the Earth's upper atmosphere. The bright lights are associated with a phenomenon known as Transient Luminous Event (TLE), which was captured by Nichole Ayers while orbiting above Mexico and the United States.
Sprites are a type of TLE, which create brilliant flashes of light high above powerful thunderstorms and are difficult to observe from the ground.
"Just. Wow. As we went over Mexico and the US this morning, I caught this sprite," wrote Ms Ayers on X (formerly Twitter).
"Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below," she added.
The NASA astronaut said they had a great view of the unique space phenomenon above the clouds which could help scientists "better understand the formation, characteristics, and relationship of TLEs to thunderstorms".

Social media reacts
As the image went viral, social media users reacted in awe and expressed fascination at how nature can conjure such a spectacle.
"Funny how we separate everything with borders when up there it's all one place," said one user while another added: "This is the best orbital sprite image I have ever seen."
A third commented: "I simply cannot imagine how amazing it would be to see this sort of thing from the space station."
As per NASA, the ISS crew members capture TLEs using wide focal lengths during Earth time-lapses. Instruments mounted outside the station, like Atmosphere-Space Interactions Monitor (ASIM), can capture a range of data for researchers on Earth using cameras, photometers, X-ray and gamma-ray detectors.

Ax-4: Students go orbital with Shux in live chat

1 2 Lucknow: From floating dinners to ceiling-less sleep, students at City Montessori School, Lucknow — alma mater of astronaut Shubhanshu Shukla — were treated to a rare window into life aboard the International Space Station (ISS) during a live interaction on Thursday. Speaking from orbit as part of Isro's Vidyarthi Samvad programme, Shukla — the first Indian aboard the ISS — shared anecdotes from his Axiom-4 mission journey. "The launch was powerful and unforgettable," he said, before delving into everyday life in microgravity. "There's no up or down here. We sleep secured inside sleeping bags. Otherwise, we might drift into another module! Meals, too, are tailored for space, with astronauts pre-selecting dishes they enjoy. We test different foods before launch — whatever we like, gets packed," Shukla said. Curious minds also asked about health in orbit. "We carry a medical kit and are trained to handle small issues," Shukla assured. Addressing the physical toll of space, he said: "In weightlessness, muscles weaken fast. So, we work out daily — cycling while floating and using resistance machines." Shukla's description of Earth from above drew audible gasps from the audience. "It's beautiful," he said. Also present was Gaganyaan astronaut-designate Group Captain Angad Pratap, who urged students to chase careers in science and space. "India's space future is bright. You could be the next to launch," he said, inspiring wide-eyed applause. In a separate 10-minute communication, a group of 70 students got lucky on Friday as they tuned into a HAM radio session with Shukla, who spoke to them from the ISS. At the Isro's UR Rao Satellite Centre (URSC) in Bengaluru, Shukla spoke to them about life on the ISS, the travel there, and how excited he was about his scientific experiments. He also told them that he was excited about his research work, especially those involving stem cells. The URSC communication was facilitated through the global Amateur Radio on the International Space Station (ARISS) initiative. Though 20 questions were shortlisted for Shukla, only a handful could be asked owing to time constraints. Isro did not broadcast the interaction live, but several amateur (HAM) radio operators worldwide managed to capture parts of the downlink, albeit with patchy audio. In one audible section, Shukla described the docking: "...The entire process of how the capsule approaches the station and then positions itself right in line with the docking port, and thereafter goes ahead and docks into the port... It was a very, very exciting moment for me." While details of all 70 students were not made available publicly, Mysuru-based Excel Public School said six of their licenced student HAM operators — Bhuvan PM (call sign: VU2NQH), Namasyu A (VU3IHV), Tanish Tejaswi MS (VU2ITM), Pranav CN (VU3IIC), Vishruth R (VU3IIB), and Sanat Raj G (VU3IHU) — established radio contact using ARISS ground station infrastructure. "This is a once-in-a-lifetime opportunity to apply what we've learnt in real time," said a statement from the students, who were in Bengaluru for the interaction. The school's HAM club (VU2TQA), active since 2023, does satellite tracking, antenna building and ISS signal decoding. Recognised as an Isro Space Tutor, Excel regularly conducts astronomy outreach. "It's a proud moment for our students and for India," said Mathew KG, the principal.

Exclusive - Biology Beyond Earth: How Space Station Is Shaping Human Life in Space

Indian astronaut Group Captain Shubhanshu Shukla is visiting a home away from Earth that has seen continuous human presence for a quarter of a century and is floating around 400 kilometres above Earth. For most millennials, the idea of humans living and working in space has been a constant reality. Since November 2000, the International Space Station (ISS), a football-field-sized laboratory orbiting 400 kilometres above Earth, has hosted a continuous human presence. But beyond the awe of astronauts floating in microgravity, the ISS has quietly become one of the most important biological laboratories in human history. In an exclusive conversation with NDTV, influential NASA biologist Dr Sharmila Bhattacharya shared how two decades of biological research aboard the ISS are not only preparing us for long-duration missions to the Moon and Mars but also transforming our understanding of human health on Earth. A Living Lab in Orbit "The first few years were about building the station," Dr Bhattacharya explained. "But for the last 15 to 20 years, we've been doing very active science as an international community." That science spans a wide range of biological disciplines. Researchers studied how spaceflight affects muscle loss, bone density, cardiovascular health, immune function, and even kidney-stone formation. These studies are essential because space is an extreme microgravity environment, radiation and isolation take a toll on the human body. And yet, astronauts have not only survived but thrived. "They go fit and come back fit," said Dr. Bhattacharya. "But that's because they're some of the fittest people on Earth and follow strict exercise and diet regimens." The Brain in Space One of the most fascinating areas of research has been the effect of spaceflight on the brain. Dr Bhattacharya's team used fruit flies, Drosophila, as a model organism to study neurological changes. "We found that in space, there were definite effects on the brain," she said. To test whether these effects could be mitigated, her team created artificial gravity using a centrifuge aboard the ISS. "We were able to partially reverse some of the defects we saw in the nervous system," she noted. This has major implications for future missions, especially those lasting years, such as a round trip to Mars. Preparing for Mars A journey to Mars could take six to nine months one way, with astronauts staying for several months before returning. That means humans will need to survive in deep space for up to two years, facing elevated radiation and reduced gravity. "The ISS has taught us a lot about microgravity," Dr Bhattacharya said. "But the Moon has one-sixth Earth's gravity, and Mars has one-third. We need to understand how partial gravity affects biology." A recent collaboration between NASA and the Japanese Space Agency used mice to study biological changes under different gravity levels-Earth, Moon, Mars, and microgravity. "It was a really interesting experiment," she said, adding that "because it helped identify thresholds where certain biological systems begin to change." Plants in Space: More Than Just Food Beyond human biology, the ISS has also become a greenhouse in orbit. Astronauts have successfully grown lettuce, tomatoes, and other crops. "Some of the tomatoes were very well appreciated by the crew," Dr. Bhattacharya said. Plant habitats on the ISS are not just functional; they are emotional anchors. "They're well-lit, so when crew members celebrate birthdays or holidays, they often gather near the plants. It's like the beautiful garden in space." These experiments are crucial for future missions, where astronauts will need to grow their food. They also help scientists understand how plants respond to microgravity, which could lead to agricultural innovations back on Earth. The Microbial Frontier Space is also a frontier for microbiology. Dr Bhattacharya's team studied how bacteria behave in space and found that some, like Serratia marcescens, became more virulent after spaceflight. "They killed fruit flies faster than bacteria that hadn't gone to space," she said. Interestingly, this increased pathogenicity disappeared when the bacteria were grown again on Earth. "We wanted to understand the molecular biology behind that change and what made them more dangerous in space," she explained. "These enclosed environments give us insights into microbial ecosystems, not just in space but also in places like submarines or hospitals on Earth," Dr Bhattacharya said. Astronauts as Test Subjects Over 600 astronauts have flown to space, many of them to the ISS. Their bodies have become invaluable data sources. "We've grown multiple generations of fruit flies, Caenorhabditis elegans, and even plants in space," Dr. Bhattacharya said, adding that "Now we're doing longer and longer experiments." One of the most exciting upcoming studies involves MRI scans of astronauts' brains before and after spaceflight, as part of the Axiom 4 mission. "Given what we've seen in fruit flies, I'm very interested to see what the human data shows," she said. The End of an Era, and the Start of Another The ISS is expected to be retired by 2031. But Dr Bhattacharya is optimistic. "I celebrate what the ISS has given us," she said. "But I'm also looking forward to the next platform." That next step could be a commercial space, perhaps Axiom, Haven, or VAST. China already has its space station, and India is planning one too. "The more platforms we have in space, the more science we can do as a global community," she said. Why It Matters for Earth While the focus is often on preparing for Mars, the benefits of space biology are already being felt on Earth. From understanding immune responses to developing better exercise regimens, the research done in orbit is improving healthcare on the ground. "Basic biology helps us understand not just how to live in space, but how to live better on Earth," Dr Bhattacharya said. A New Age of Exploration As humanity looks beyond Earth, the ISS stands as a testament to what international cooperation and scientific curiosity can achieve. It has been a proving ground for the biology of the future where humans may one day live on the Moon, Mars, or even beyond. And thanks to scientists like Dr. Sharmila Bhattacharya, we're not just dreaming about that future, we're building it, one fruit fly at a time.

Shux completes Tardigrade experiment, three other experiments ongoing

BENGALURU: Group Captain Shubhanshu Shukla, onboard the International Space Station (ISS), has his hands full. As part of his 14-day-long stay and expedition to the ISS under the Axiom-4 manned space mission, he has completed the Tardigrade Experiment. Sharing the details on Friday, ISRO said Shux, who is also one of the four chosen astronauts for the Gaganyaan mission, has completed the microgravity experiment involving Tardigrades onboard ISS. "The study focused on their survival, revival and reproductive behaviour in space. This study will provide valuable insights into the underlying biological mechanisms leading to resilience of extremophile organisms in a microgravity environment and has potential applications on Earth, especially in the area of therapeutics," the ISRO team in its release said.
