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

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by ...

A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...

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, ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star ...

Using spectral data from the Hobby-Eberly Telescope at McDonald Observatory, astronomers have produced the most detailed 3D map yet of faint cosmic structures from 9-11 billion years ago, revealing ...

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 ...

Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they ...

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