Our universe is full of mysteries, but few are as perplexing as the dark, tiny galaxies that hover around larger ones like ...

A model of the cyclic universe suggests that dark matter could be a population of black holes predating the Big Bang.

The difference is like a crowd of people who ignore each other versus one where everyone is constantly bumping into one ...

Dark matter has been thought to be cold and collisionless, meaning its particles don't interact with each other. The new study, however, challenges this assumption.

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

Dark matter decays could be the missing ingredient explaining how giant black holes formed before the first stars ...

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...
