Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

Researchers suggest that dark matter might subtly color light red or blue as it passes through, revealing traces of its existence. Using a network-like model of particle connections, they argue that ...

Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as scientists long believed. New research shows that dark matter particles could have ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

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 ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

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 ...

Scientists are shining a brighter light on dark matter thanks to a new high-resolution map, unveiling the invisible material that shapes everything we see. Using James Webb Space Telescope’s (JWST) ...
