The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, ...

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 ...

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 ...

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the ...

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 ...

The notion that our universe might be a giant simulation has intrigued scientists and philosophers for decades. Recent advancements in technology and theoretical physics have reignited this debate, ...

Most of the (dark) matter beyond the Local Group of galaxies (which includes the Milky Way and the Andromeda Galaxy) must be ...
