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.

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

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.

Located 50 light-years from Earth, the beady-eyed exoplanet LHS 1140 b could be a perfect candidate for discovering liquid water outside the solar system, new research suggests.

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.

A new multiwavelength 3D visualization of the iconic "Pillars of Creation" showcases the differences between Hubble and James Webb Space Telescope data.

Astronomers using the James Webb Space Telescope (JWST) have spotted a previously unseen structure in the atmosphere above Jupiter's famous Great Red Spot.

Astronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin arc of glittering stars. The discovery could help them understand how the earliest galaxies formed.
