The Milky Way isn't just drifting through a giant void in space untethered, but is embedded in a sheet of dark matter like a ...

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, ...

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

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 ...

A recent paper reveals we're almost certainly going to collide with a galaxy in the next couple billion years, but it's not the one we thought. Reading time 2 minutes For over a decade, researchers ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...

Few scientific ideas have leapt from philosophy seminars to dinner-table debates as quickly as the claim that our universe might be an artificial construct. The simulation hypothesis promises a ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, hydrogen-blue glow that had mostly escaped surveys until now.
