The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for how physics may work on large scales, according to a team of astronomers.

The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.

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.

New theoretical research suggests primordial black holes could one day help researchers locate invisible dark matter.

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.

Maggie Aderin-Pocock tells us about the power of the James Webb Space Telescope and how she inspires disadvantaged students to enter STEM.

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

The secrets of black holes and dark matter could lie before the Big Bang, a new study of "bouncing" cosmology hints.

From the moment of the Big Bang, everything in the universe has kept moving, but why is that?

The new AI system can estimate cosmological parameters with stunning precision, and it could help astronomers unpick one of the thorniest problems in the field.
