Scientists have long known that most of the matter in the universe is invisible. This hidden material, called dark matter, ...

No theory could explain the slight excess of far-ultraviolet light in the Milky Way until now.

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 another,’ says scientist ...

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.

A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...

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

Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

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 ...

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 ...
