Research published Tuesday by a Japanese astrophysicist says gamma rays may have been generated by the collision of dark ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, ...

A new study claims to show evidence of gamma-ray emissions that closely resemble those expected from two weakly interacting ...

A strange, never-before-seen glow in the halo of our galaxy may be the strongest dark-matter breadcrumb yet. A new analysis of 15 years' worth of data from the Fermi Gamma-Ray Space Telescope reveals ...

For decades, scientists have only inferred dark matter’s existence through its gravitational pull on galaxies, but may now ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced.

Scientists may have "seen" dark matter for the first time, thanks to NASA's Fermi gamma-ray space telescope. If so, this ...

Learn how a newly detected gamma-ray halo in the Milky Way could mark the first direct glimpse of dark matter.

“If this is correct, to the extent of my knowledge, it would mark the first time humanity has ‘seen’ dark matter. And it turns out that dark matter is a new particle not included in the current ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

Researchers have discovered nine new sources of high-energy photons in the Milky Way, including some of the most energetic gamma rays ever detected. By studying these gamma-ray sources, which all seem ...
