The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny ...

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. When you ...

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe. When you purchase through links on our site, we may earn an affiliate ...
