A decorated Indian-American Amit Kshatriya has been named as NASA’s new ‘exploration-focussed’ associate administrator, the US space agency announced here. In his new role, Amit Kshatriya serves as the highest-ranking civil servant at the agency and as a senior advisor to acting NASA administrator Sean P Duffy.(nasa.gov) Kshatriya, a 20-year NASA veteran, was most recently the deputy in charge of …

This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars. Called Pismis 24, this young star cluster resides in the core of the nearby …

The recent passing of retired Navy Capt. Jim Lovell, an astronaut and one of our great American heroes, propelled many of us back to the iconic scenes from the superb retelling of the Apollo 13 movie in 1995. The three of us lived through that fateful mission in 1970, as the astronauts and mission control team dealt with critical issue after …

The next astronauts to travel around the moon seem plenty fit to make the trip. The four astronauts who will fly on NASA’s Artemis 2 mission recently passed the “Bobby and Pete Challenge,” performing 50 pull-ups and 100 pushups in less than 10 minutes. The quartet — NASA’s Victor Glover, Christina Koch and Reid Wiseman, and Jeremy Hansen of the …

Scientists peering into the very heart of hearts of the planet Mars have found a deeply unexpected structure. There, at the innermost core of the planet, InSight seismic data reveals a solid mass about 600 kilometers (373 miles) across. This is not just in contrast to previous findings that the core is squishy all the way through – it doesn’t …

In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA’s powerful James Webb Space Telescope (JWST), they identified 300 objects that were brighter than they should be. “These mysterious objects are candidate galaxies in the early universe, meaning they could be very early galaxies,” said …

The inside of a star turned on itself before it spectacularly exploded, according to a new study from NASA’s Chandra X-ray Observatory. Today, this shattered star, known as the Cassiopeia A supernova remnant, is one of the best-known, well-studied objects in the sky. Over three hundred years ago, however, it was a giant star on the brink of self-destruction. The …

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — can help discover more about …

“We were interested in looking at the more durable systems,” Camarda told Ars. “The first thing I ever tested was actually an all-metallic shuttle wing leading edge, and it used heat pipes, and it was built by McDonnell Douglas. It was a competitor with the reinforced carbon-carbon, the passive leading edge system.” Ultimately, NASA went with the reinforced carbon-carbon heat …

NASA’s Psyche spacecraft, which is headed toward a big and bizarre metal asteroid, has delivered a stunning perspective of our home planet from deep space. Psyche launched atop a SpaceX Falcon Heavy rocket in October 2023 with the objective of visiting the metallic asteroid 16 Psyche, which is believed to be the exposed core of a demolished planetesimal, or tiny …
