Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of ...

Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it evolved from a super-heated plasma after the Big Bang to the structured cosmos we ...

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

Long before stars lit up the sky, the universe was a hot, dense place where simple chemistry quietly set the stage for everything to come. Scientists have now recreated the first molecule ever to form ...

The early universe was already warm before reionization, revealing that the first stars did not flicker on in an icy cosmos.

Astronomers using the James Webb Space Telescope have uncovered mysterious “little red dots” that may not be galaxies at all, but a whole new type of object: black hole stars. These fiery spheres, ...

Since its launch in late 2021, the James Webb Space Telescope (JWST) has been glimpsing some of the earliest epochs of cosmic time. Its observations have stretched cosmologists' timelines of when ...

Even before the first stars lit up the Universe, the Cosmos was not the cold place most researchers once imagined. New results suggest that the so-called cosmic “dark ages,” the muted era between the ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected. This article was originally published at The Conversation. The publication ...
