Supernova that lit up Earth's skies 843 years ago has a flowering 'zombie star' at its heart — and it's still exploding
A new animated map sheds light on the superhot "zombie star" at the heart of a nebula leftover from a distant supernova witnessed by astronomers in 1181. The remains of the stellar explosion are unusually wonky and are still exploding at a constant speed.
Euclid telescope reveals 1st section of largest-ever 3D map of the universe — and there's still 99% to go
The first piece of the Euclid space telescope's map of the universe is crammed with 14 million galaxies and 100 million sources of light. The mapping project is now 1% done.
James Webb telescope discovers 'inside out galaxy' near the dawn of time
A bright spiral galaxy appears on a background of thousands of other distant galaxies
The Milky Way could be part of a much larger 'cosmic neighborhood' than we realized, challenging our understanding of the universe
A probabilistic new map of the universe surrounding the Milky Way reveals that our galaxy is likely part of an even larger "basin of attraction" than we previously assumed.
Are we wrong about the age of the universe? The James Webb telescope is raising big questions.
Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.
Record-breaking ancient spinning galaxy challenges cosmic evolution theories
Astronomers have discovered the earliest strongly rotating galaxy ever seen that's well-organized rather than chaotic, challenging theories of cosmic evolution.
The James Webb telescope has brought cosmology to a tipping point. Will it soon reveal new physics?
Right now, it looks like cosmology is at a tipping point. Will the James Webb telescope resolve the issue by revealing new physics?
One of the universe's biggest paradoxes could be even weirder than we thought, James Webb telescope study reveals
New James Webb Space Telescope results have revealed that there may not be a Hubble tension after all. But contradictions within the findings point to a deeper mystery.
