Astronomers have created an enormous 3D map of the universe revealing a glowing “sea of light” from hydrogen gas during the cosmic dawn nearly 11 billion years ago.

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

For decades, astronomers have struggled to visualize the universe during its early stages, when galaxies were forming and cosmic structures were taking shape. While the brightest galaxies are visible ...

What did galaxies look like in the early universe and how did they form and evolve over time? This is something that NASA’s James Webb Space Telescope (JWST) hopes to reveal as it recently observed a ...

Everything we know about the evolution of the early universe is currently being challenged. Multiple galaxies discovered by the James Webb Space Telescope do not match up with the standard model of ...

The universe is filled with galaxies — more than a trillion by some estimates — and we’ve only mapped a fraction of them. But answering some of the most pressing mysteries plaguing astronomers today, ...

There may be something wrong with our models of the cosmos. The matter in the universe is getting clumpier and clumpier over time but it appears to be happening more slowly than expected. This ...
