Astronomers have found 65 evenly spaced rocks orbiting a white dwarf star in its habitable zone, hinting that a planet’s gravity may be holding them there11 February 2022By Leah CraneIllustration of the…

When young stars coalesce out of a cloud of molecular hydrogen, a disk of leftover material called a protoplanetary disk surrounds them. This disk is where planets form, and astronomers are getting better at peering into those…

A star that exploded into brightness nearly 200 years ago can now be explored in glorious, multi-wavelength detail. In a new video, a team of scientists modeled the Homunculus Nebula around the star Eta Carinae in three…

Beyond the Solar System, out there in the wider galaxy, a very strange subset of exoplanets exists. Called hot Jupiters, these are majorly clingy – hugging so close to their host stars, they're not just intensely hot, but also…

Tom Jacobs of Bellevue, Washington, loves treasure hunts. Since 2010, the former U.S. naval officer has participated in online volunteer projects that allow anyone who is interested — “citizen scientists” — to look through #NASA telescope…

In a nearby galaxy, a rare kind of dead star erupted into a giant outburst.This in itself may not be so peculiar; but, for the first time, changes in its brightness during this event have been documented in detail, giving…

By far my favorite thing about my job as an astronomer is those rare moments when I get to see beautiful distant galaxies, whose light left them millions to billions of years ago. It's a combination of pure awe and scientific curiosity that…

Using observations and archival data from several of NSF's NOIRLab's observatories, together with observations from telescopes around the world and in orbit, astronomers have discovered at least 70 new free-floating planets—planets that…

Another analysis of known exoplanets has uncovered that #Earth-like conditions on possibly livable #planets might be a lot more extraordinary than recently suspected. The work centers around the conditions needed for oxygen-put together…

An inquisitively yellow pre-cosmic #explosion star has made #astrophysicists rethink what's conceivable at the passings of our Universe's most monstrous stars. The group portrays the curious #star and its subsequent cosmic explosion in…
