Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any instrument yet created. We know it’s out there because of the effects it has on ...

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 ...

This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While the universe is populated by visible stars and galaxies, much of its mass ...

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...

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 ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the universe's mass. While theoretical predictions hint at its abundance, detecting this ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

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 ...
