NASA Astronaut Captures Stunning 'Sprite' Light Show Above Earth's Atmosphere
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".

A view of lightning that's nothing like what we see on the ground: crew observations and instruments on the @Space_Station can help us better understand the behaviors of storms. https://t.co/uUpPJUHw9r

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.

Astronomers Discover "Water-Rich Super-Earth" Twice As Big As Our Planet
Scientists have discovered a new "super-Earth" that is located about 154 light-years away and is nearly twice as big and four times as massive as our planet. According to a paper published on the arXiv preprint server, the team of astronomers, led by Abderahmane Soubkiou of the Oukaimeden Observatory in Morocco, discovered the exoplanet using NASA's Transiting Exoplanet Survey Satellite (TESS). They stated the newly discovered alien world, designated TOI-1846 b, is likely a water-rich super-Earth and is estimated to be 7.2 billion years old. "We have validated TOI-1846 b using TESS and multicolour ground-based photometric data, high-resolution imaging, and spectroscopic observations," the researchers wrote in the paper, as per According to the study, the exoplanet has a radius of about 1.792 Earth radii and is about 4.4 times more massive than our planet. It orbits its host every 3.93 days, and the equilibrium temperature of the planet is estimated to be 568.1 K. Based on their research, scientists concluded that the new "super-Earth" is likely water-rich. But they noted that radial velocity (RV) observations of TOI-1846 b should be conducted in order to unveil its composition. "These findings make TOI-1846 b well-suited for mass determination via RV observations. This could be possible with the MAROON-X instrument. (...) We find a TSM [transmission spectroscopy metric] of 47 for TOI-1846 b, which is below the 90 benchmark for small sub-Neptunes," the authors of the paper wrote, according to the outlet. When it comes to the parent star TOI-1846, the researchers said that the exoplanet is about 0.4 times the size of the Sun, and its mass is approximately 0.42 solar masses. The star has an effective temperature of 3,568 K and is estimated to be 7.2 billion years old, study authors said. Meanwhile, earlier this year, researchers discovered another "super-Earth" located outside our solar system. The exoplanet, designated HD 20794 d, is six times the mass of Earth and could harbour liquid water on its surface. Located 20 light-years away, it orbits within the habitable zone of a star similar to our sun, according to findings from the University of Oxford. However, unlike Earth's circular orbit, HD 20794 d follows an elliptical path, making it uncertain whether the planet could support life, researchers said.

Shubhanshu Shukla shares Indian food, struggles most with sleep aboard ISS
After spending a week aboard the International Space Station (ISS), Group Captain Shubhanshu Shukla has said that sleeping is the most challenging task, not due to an overload of duties, but because of the limited time to take it all in. On June 26, Shukla made history by becoming the first Indian astronaut to set foot on the ISS. Shukla admitted during a radio interaction with Indian school students that despite the thrill and importance of the mission, winding down proved unexpectedly hard. 'The most difficult task is going to sleep — not due to noise or discomfort, but simply because you're so aware of how limited your time is. You want to experience and accomplish as much as possible,' he shared. When asked if he shared Indian food items like amras, moong dal halwa, and gajar ka halwa, specially developed by DRDO and Isro, with his fellow astronauts, the 39-year-old said, 'I must tell you that everybody here loved it. We all sat together and shared food from our respective countries — it was a truly special moment. The Indian dishes were not only appreciated for their taste, but also for bringing a sense of home to space.' Collaboration beyond borders, says Shubhanshu Shukla Reflecting on the dynamic launch and the experience of space travel, Shukla said, 'The rocket ascent was extremely fast. You feel strong accelerations — especially as the second stage propels you to nearly 8 kilometres per second.' Yet, what moved him most was the view of the earth from above. 'It is vast, it is stunning, and it reminds you just how lucky we are to be on this planet,' he said. Shukla also noted the value of working with astronauts from diverse nations. 'The Axiom-4 mission is a true example of global collaboration — combining technology, cultures and knowledge,' he said. Shukla sets record, logs most days in space by an Indian By July 3, Shubhanshu Shukla had spent over nine days in orbit, surpassing the record previously held by Rakesh Sharma, who was in space for seven days, 21 hours, and 40 minutes during the 1984 Soviet Interkosmos programme. Group Captain Shukla's participation in Axiom-4 marks a significant chapter in India's space journey. During the mission, Shukla is conducting seven indigenous experiments and five collaborative studies with Nasa. 'All the experiments are fascinating, but I find the one on stem cells particularly interesting,' he said. The microgravity environment, he explained, provides a unique platform for cellular research that could have far-reaching implications for both space science and healthcare on the earth. Launched from the Kennedy Space Centre in Florida on June 26, the Axiom-4 mission includes Commander Peggy Whitson (USA), Shukla as pilot, and mission specialists Slawosz Uzna?"ski-Wiśniewski (Poland) and Tibor Kapu (Hungary). Since docking, the crew has completed over 113 orbits around the earth, covering more than 2.9 million miles — nearly twelve times the distance to the moon.

Sleeping on ISS most difficult task: Shubhanshu
A week on board the International Space Station (ISS), Group Captain Shubhanshu Shukla says sleeping is difficult. Not because there's too much to do, but because the time is limited. On June 26, Shukla scripted history on being the first Indian astronaut on board ISS. Group Captain Shubhanshu Shukla 'The most difficult task is to go to sleep because of the time that is around you. You know you are here for a short time and you want to do more and more,' said Shukla during his interaction with school students from India via Ham radio on Friday afternoon. 'But as you understand that there are activities planned, you also need to get rest.' In his 10-minute communication starting 3.47pm, Shukla, who connected to Isro's UR Rao Satellite Centre, Bengaluru, answered questions on his experience flying to space, experiments he is undertaking and importance of international collaboration for the success of a space mission like Axiom-4. His outreach via amateur radio interaction was livestreamed by Space India, which is an educational organisation working with schools across India. Since docking on June 26, the astronauts by end of July 3, have completed approximately 113 orbits around Earth, covering over 2.9 million miles - that's nearly 12 times the distance between Earth and the Moon. During his two- weeks on ISS, Shukla, who represents Isro, has been commissioned to perform seven home grown experiments and five scientific studies as part of Isro-NASA collaboration. Describing all the experiments as challenging and exciting, Shukla said he particularly finds a few that he is conducting on ISS 'interesting'. 'Especially the one concerned with stem cells,' he pointed. As exciting as the experience has been, Shukla also said it's hard since the body has to adapt to new conditions. On being asked if he shared the Indian food - amras, moong dal halwa and gajjar ka halwa developed by DRDO and Isro - with other astronauts, the 39-year-old said, 'I must tell you that everybody here loved it and we sat together and shared the food and they appreciated how good these were. And it was a good moment. We brought together foods from different countries and got to share it together with all the crew on the station.' Stating that rocket launch was very dynamic, the Lucknow resident recounted his journey to ISS. 'The experience was exhilarating.. (the rocket launch) was very fast, and as you go higher you go faster. The accelerations were quite high.' As he explained that the rocket goes in two stages, Shukla said, 'The first stage was fast. And the second stage accelerates due to the velocity of 8kms per second.' He pointed out that the Ax-4 mission was the 'power of global collaboration', one that allowed him to look at the earth from space. 'It (the earth) is big. It is very beautiful and it reminded me of how fortunate we are to be in this planet and with everything we have.' A week on ISS, a statement from Axiom Space read, 'In just seven days, the Ax-4 astronauts have already made significant contributions to scientific more than a hundred sunrises and sunsets witnessed from orbit, the Ax-4 mission is advancing science progress in space and inspiring a new generation of explorers.' By the end of their time on ISS, the Ax-4 mission comprising commander Peggy Whitson, mission pilot Shukla and mission specialists Sławosz Uznański-Wiśniewski and Tibor Kapu would have conducted 60 experiments representing 31 countries.
