Cosmology

Astronomers have discovered the earliest strongly rotating galaxy ever seen that's well-organized rather than chaotic, challenging theories of cosmic evolution.

Right now, it looks like cosmology is at a tipping point. Will the James Webb telescope resolve the issue by revealing new physics?

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 bottom line is, there is no crisis in terms of the standard model of cosmology.

Scientists might be on track to revealing new facets of physics.

Astronomers have long predicted that a collision between our galaxy and nearby Andromeda could be inevitable, but new calculations suggest this may be an over exaggeration.

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?

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.

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.
