Nasa releases 5,00,000 images of galaxies, needs your help to identify them

India Today30-04-2025
Nasa has released images of 5,00,000 galaxies taken by the James Webb Space Telescope and it needs the help of citizen scientists in identifying the shapes of these objects.The classification could help scientists answer questions about how the shapes of galaxies have changed over time, what caused these changes, and why.The images have been released on the website of the Galaxy Zoo citizen science project, where the visitors will first examine an image from the Webb telescope, and then will be asked several questions, such as 'Is the galaxy round?', or 'Are there signs of spiral arms?'.advertisement
Nasa has said that if you're quick, you may even be the first person to see the galaxies you're asked to classify."This is a great opportunity to see images from the newest space telescope. 'Galaxies at the edge of our universe are being seen for the first time, just as they are starting to form. Just sign up and answer simple questions about the shape of the galaxy that you are seeing. Anyone can do it, ages 10 and up," volunteer Christine Macmillan from Aberdeen, Scotland told Nasa.Galaxy Zoo volunteers have been exploring deep space since July 2007, starting with a million galaxies from a telescope in New Mexico called the Sloan Digital Sky Survey and then, moving on to images from space telescopes like NASA's Hubble Space Telescope and ESA (European Space Agency)'s Euclid telescope.advertisementNasa said that the pictures of the galaxies show how they were billions of years ago because light takes time to travel to us. "With Webb, we can spot galaxies at greater distances than ever before. We're seeing what some of the earliest galaxies ever detected look like, for the first time," Nasa said.The shapes of these galaxies could reveal how they were born, how and when they formed stars, and how they interacted with their neighbours.

Can Magnets Help Astronauts Breathe On Mars? NASA Shares Video Of Radical Tech

Last Updated: NASA Mars Oxygen Tech: From water to breathable air, NASA's new concept could reshape life support for deep space travel. NASA Mars Oxygen Tech: A future where astronauts breathe air on Mars not through bulky machines but through the quiet play of water, magnets and microgravity may not be science fiction for long. That is the vision behind a new study led by the Georgia Tech Research Corporation in collaboration with commercial partner Giner Labs, a long-time leader in space electrolysis technology. Living and working on Mars is not only about landing rockets or building habitats. It is also about something as basic as breathing. Astronauts on long journeys and on the Red Planet will need a steady, reliable source of oxygen, a resource that cannot be shipped in tanks from Earth. To meet that challenge, researchers working with NASA's Innovative Advanced Concepts program are testing an idea that sounds almost magical: using magnets and swirling water to make air in space. NASA, sharing a video on Wednesday, explained the project in a post that read, 'Living and working on Mars will require innovative technologies to produce oxygen for future explorers. That's why researchers, working with NASA's Innovative Advanced Concepts program, are developing a powerful new idea using swirling fluids and strong magnets to produce breathable air." At the heart of this concept is a magnetohydrodynamic electrolytic cell, a system that can split water into oxygen and hydrogen without any moving parts. In microgravity, where pumps or centrifuges are difficult to operate and maintain, this could be a game changer. Current machines depend on loops of water, pumps and filters to separate gases from liquids. In the new system, powerful magnetic fields take over the job, guiding the fluids so that oxygen and hydrogen separate naturally. Researchers estimate that this approach could reduce the weight and complexity of oxygen-generating equipment by as much as 50 percent compared to existing systems like the Oxygen Generation Assembly used on the International Space Station. For a Mars-bound crew of four, who would together consume around 3.36 kilograms of oxygen each day, such savings could mean lighter spacecraft, fewer spare parts and a more reliable life support system. If the concept proves successful, its impact could go beyond life support. The same principles could be used in water-based propulsion for small satellites or in future missions that harvest Martian ice to make oxygen and fuel directly on the planet. view comments First Published: Disclaimer: Comments reflect users' views, not News18's.

Watch: Meteor Falls On Earth, Rare Crash Recorded On Camera

Last Updated: A rare celestial event stunned onlookers in Canada and it was all caught in an unexpected way. In January 2025, Joe Wellidman from Prince Edward Island, Canada, witnessed a jaw-dropping sight while out walking his dog. A meteor, blazing through the sky at nearly 60,000 km/h, crashed to Earth—an event his home's doorbell camera recorded in full, sound included. This marks the first-ever instance of a meteor impact being captured with audio. While meteors are common during events like the Perseid meteor shower, catching one on camera is incredibly rare. What Are Meteors? Meteors are fragments of rock or metal from space that enter Earth's atmosphere. Every day, around 44,000 kilograms of meteoritic material falls toward Earth. Most of it burns up before reaching the ground, but some pieces make it through. NASA estimates that about 48 tons of space debris hits Earth daily—yet being recorded as it lands is an exceptional occurrence. Scientists say the risk of dying from a meteor strike is extremely low. According to Professor Carrie Nugent, the odds of being hit by a 140-meter asteroid are higher than being killed by lightning—but still extremely rare. The risk is lower than being attacked by an elephant or a wild wolf. Historic Meteor Incidents Confirmed deaths from meteors are almost unheard of. In 1888, in Iraq, a young man reportedly died after being struck by a meteor, according to Ottoman Empire records. Another famous case occurred in 1954, in Alabama (USA), when a meteor tore through a woman's roof and struck her while she slept. She survived but was left with a massive bruise. Such incidents highlight just how extraordinarily rare these encounters are. view comments First Published: Disclaimer: Comments reflect users' views, not News18's.

It's A Bird, It's A Plane? No, It's A Blazing Meteor Turning Japan's Night Into Day

A fireball streaked across western Japan, astonishing residents and stargazers. Experts confirmed it was a bright meteor. A flashing fireball streaked across the skies of western Japan, astonishing residents and captivating stargazers. Experts said the dazzling display was a natural phenomenon, not an alien invasion. The bright ball of light was visible across hundreds of miles shortly after 11:00pm local time (14:00 BST), according to eyewitnesses and footage widely shared online. 'A white light I had never seen before came down from above, and it became so bright that I could clearly see the shapes of the houses around us," Yoshihiko Hamahata, who was driving in Miyazaki prefecture, said. Meteor/fireball lights up Sakurajima volcano and Kagoshima City in Japan tonight ☄️ — Volcaholic 🌋 (@volcaholic1) August 19, 2025 He told local media, 'It seemed like daylight. For a moment, I didn't know what had happened and was very surprised." Toshihisa Maeda, head of the Sendai Space Museum in Kagoshima prefecture, identified the phenomenon as an exceptionally bright meteor. He said it appeared to have descended into the Pacific Ocean. 'People reported feeling the air vibrate. It was as bright as the moon," he told local media. NASA said that objects responsible for such fireballs can be larger than one metre (3ft). Those that explode in the atmosphere are technically known as bolides, though the term fireball is commonly used. view comments First Published: August 20, 2025, 17:01 IST Disclaimer: Comments reflect users' views, not News18's.
