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

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. A team had found a small, strange galaxy that appeared to ...

The research could shed light on how black holes vomit out matter and how this influences their home galaxies.

Humanity has always been fascinated by space. We are able to see the universe with breathtaking clarity because of NASA's powerful telescopes. Astronomers have been able to take pictures of galaxies ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Astronomers discover PicII‑503, a 14-billion-year-old star carrying primordial elements, challenging theories of early star ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those fields formed so fast. Observations from the Atacama Large ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.
