Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

T he first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

Scientists have detected oxygen in the most distant galaxy ever found, suggesting that early galaxies formed more rapidly than previously thought. The record-breaking discovery, reported by two teams ...
