Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe’s

New theory makes testable predictions.

Scientists have conflicting theories on why the universe is expanding at an accelerating rate. New measurements from a massive collaboration complicate these ideas.

Astronomers have identified a bright hydrogen emission from a galaxy in the very early Universe. The surprise finding is challenging researchers to explain how

Gravitational waves data held clues for high-mass black holes’ violent beginnings

Scientists have spotted a massive black hole in the early universe that is ‘napping’ after stuffing itself with too much food.

The universe is constantly expanding, but how do scientists think about what it’s expanding into?

At a singularity, the laws of physics as we know them suffer a complete breakdown. So such objects really shouldn’t exist.
