Even before the first stars lit up the Universe, the Cosmos was not the cold place most researchers once imagined. New ...

A surprising new study reveals that the first stars appeared in a pre-heated universe, challenging earlier ideas about early cosmic conditions.

The first stars in the universe formed out of pristine hydrogen and helium clouds, in the first few hundred million years ...

New data from the James Webb Space Telescope may solve a riddle from the universe’s beginnings. A compact, distant object ...

A growing list of dark star candidates could help explain why some early galaxies were so big, so early in the universe.

The James Webb Space Telescope does not observe things like a regular camera that we would have on our cell phones. Instead, ...

Star formation is a fundamental physical process in our universe. Stars light up the cosmos, and give rise to planets, some ...

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a ...

The James Webb Space Telescope has observed 'inside-out' star formation in a galaxy just 700 million years after the Big Bang ...

"This gives us a new way to rule out certain black hole scenarios for dark matter." New research suggests that primordial black holes created during the Big Bang could have played a major role in ...

"The research suggests this heating is likely driven by the energy from early sources of X-rays from early black holes and stellar remnants spreading through the Universe," said Professor Cathryn ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected.
