New simulations tilt the scales for competing theories about excess gamma ray light at the center of the galaxy ...

"If axion clouds, and thereby axions, are discovered, this would be a massive step toward solving the dark matter problem." When you purchase through links on our site, we may earn an affiliate ...

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons ...

Quark matter may join solid, liquids, gases, and plasmas as a newly-understood state of matter. Far from being exotic, a new study suggests that quark matter could make up a large percentage of the ...

An excess of gamma rays in the center of our galaxy could mean scientists have finally detected dark matter particles—or not ...

At the heart of the Milky Way, a faint and widespread glow of gamma rays has puzzled astronomers for decades. The light could ...
