James Webb Space Telescope

These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.

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.

The James Webb Space Telescope has uncovered six "rogue planets" careening through space without a star. The objects are believed to have formed directly from gas collapse, blurring the lines between planets and stars.

A new image of the Serpens Nebula captured by the James Webb Space Telescope shows that when clouds collapse to form stars, all of those stars spin in the same direction.

A new James Webb Space Telescope analysis of the giant, metal-rich asteroid Psyche reveals signs of hydration in the form of rust. This could help pin down the mysterious rock's origins.

The light from the most distant galaxy in the known universe suggests that there's something off about our current cosmological models, a new James Webb Space Telescope study finds. The explanations remain elusive.

While headlines around the world claimed that ancient galaxies discovered by the James Webb Space Telescope were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old?

To mark its second anniversary of operations, James Webb Space Telescope scientists share a stunning view of the Penguin and Egg galaxies as they slowly collide.

New photos from the James Webb Space Telescope show off the bewitching beauty of the warped quasar RX J1131-1231, which is adorned with four bright spots birthed by mind-bending space-time trickery.
