NASA’s James Webb Telescope may have detected the universe’s first stars, Pop III stars, in galaxy LAP1-B, offering a glimpse into cosmic history.

An international team of astronomers announced the two earliest and most distant galaxies yet confirmed were detected by the James Webb Space Telescope. The two galaxies are believed to date back to ...

Forget one Big Bang — try many. A bold new theory pokes holes in the popular origin story, suggesting the universe evolves through a series of lightning-fast bursts, rewriting what we know about ...
