Dark Matter

A mysterious abundance of high-energy light near the Milky Way's core likely isn't a sign of elusive dark matter after all, a new study suggests.

Researchers have produced what they say is the first composite image of a dark matter filament that connects galaxies across the cosmos.

How much dark matter has gone missing since the Big Bang? New research suggests anywhere from 2 to 5 percent.

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests.

Computer simulations suggest that filaments of invisible dark matter form long "hairs" when they go through planets such as Earth.

Dark matter particles may have interacted often with normal matter long ago, when the universe was very hot, a new study suggests.

Dark matter might be made of clouds of energy cracks instead of particles and may be detectable in GPS signals.
