Though Halloween will undoubtedly take the spotlight today, there's another spooky event worth celebrating. Thursday (Oct. 31) marks this year's Dark Matter Day as well, a time during which scientists ...

In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

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 ...

"It's possible we will see the new data and confirm one theory over the other — or maybe we'll find nothing, in which case it'll be an even greater mystery to resolve." When you purchase through links ...

At the center of our galaxy, there’s a mysterious, diffuse glow given off by gamma rays — powerful radiation usually emitted by high-energy objects such as rapidly rotating or exploding stars. NASA’s ...

For decades, dark matter has been the universe’s most stubborn mystery, silently shaping galaxies while refusing to show itself to our instruments. Now a bold new claim from a Japanese astronomer ...

Dark matter makes up 85% of the stuff in the cosmos, but scientists have no idea what it is. Can you solve the case? When you purchase through links on our site, we may earn an affiliate commission.

Gamma-ray intensity map excluding components other than the halo, spanning approximately 100 degrees in the direction of the Galactic center. The horizontal gray bar in the central region corresponds ...
