Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have ...

For centuries, people have looked to the stars, asking how it all began—and how it might end. Now, thanks to a bold new study ...

A telescope near Tucson has helped scientists produce the largest 3D map of the universe ever made and uncover confounding evidence that could change our understanding of dark energy.

Dark matter remains one of science's deepest mysteries. It makes up about 25% of our universe, yet scientists only observe ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

New research suggests sub-stellar objects called dark dwarfs could glow forever on dark matter energy. Could they reveal secrets about the universe’s hidden mass?

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

The EPA bases its climate policy on research that's often irreplicable, incomplete, or even just weak—and it's time for that ...

Brown dwarfs are too small to sustain the nuclear fusion that powers most stars, so they cool and fade over time. But if they sit in a dense pocket of dark matter, like near the Milky Way’s centre, ...

Dark matter pulls the universe and dark energy pushes, both mysteries that endure. And the discovery that a majority of the universe is made up of “stuff” that makes gravity push rather than ...

Scientists predict up to 100 invisible galaxies may orbit the Milky Way, hiding just beyond our current detection limits.

A new kind of cosmic object could help solve one of the universe's greatest mysteries: dark matter.Particle Astrophysicists have proposed the ...
