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

The data is starting to reveal how galaxies and their black holes evolve.

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

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 ...

Astronomer and Queen guitarist Brian May teams up with astrophysicist Derek Ward-Thompson to bring the cosmos to 3D.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Astronomers may have finally explained why the Small Magellanic Cloud isn’t spinning like it should. In a new study published on Monday in the Astrophysical Journal, researchers used computers to ...

A new high-resolution map of distant galaxies may help scientists understand a mysterious invisible substance that helps hold the universe together. The ordinary matter all around us — stars, planets ...
