We think of galaxies as ancient. Our own galaxy, the Milky Way, formed 13.6 billion years ago, and the James Webb Space Telescope has allowed us to peer back to some of the first galaxies in the early universe. But are galaxies still being born today?It's a fun question to tackle because it lets us dig into the messy, complicated, beautiful…

CNN  —  SpaceX’s stalwart Falcon 9 rocket, which powers satellite launches as well as trips to orbit for NASA astronauts, experienced a rare failure Thursday night at it attempted to haul a batch of internet satellites to…

You can only imagine what sort of things are hurtling through an astronaut's head while they've got a birds eye view of our planet from space - but I reckon 'that's a long way down' might be a leading contender.But for former NASA space cadet Ron Garan, 62, there was only one thing on his mind...the 'sobering realisation' that us Earthlings are…

Researchers at the University of Toronto Engineering have developed a new catalyst that efficiently converts captured carbon into valuable products such as ethylene and ethanol, even in the presence of sulfur oxide contaminants. This breakthrough offers a more economically viable method for carbon capture and upgrading, potentially…

NASA tracked two near-Earth asteroids, capturing important data about their trajectories and physical characteristics using radar technology, which supports ongoing planetary defense efforts. (Artist’s concept.) Credit: SciTechDaily.comThe Deep Space Network’s Goldstone planetary radar had a busy few days observing asteroids 2024 MK and 2011…

SpaceX’s plan to launch its monstrous Starship-Super Heavy two-stage tandem from NASA’s Kennedy Space Center caught the attention — and concern — of two rival space companies that warn federal officials the up-to-492-foot-tall rocket will be too untested, too dangerous and too potentially disruptive for the nation’s busiest spaceport and the…

Researchers investigated three mysterious objects in the early universe. Shown here are their color images, composited from three NIRCam filter bands onboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the term “little red dots”), with some evidence for spatial structure at blue wavelengths.…

NASA/JPL-Caltech NASA's Goldstone Solar System Radar recently observed asteroid 2024 MK, which made its closest approach of Earth on June 29.…
