On the largest scales accessible to observation, the universe appears to match the current cosmological model, which is dominated by dark matter and dark energy. However, in galaxies, the interplay ...

In popular science, dark matter is a hotly discussed topic. With various theories regarding its existence and interaction with regular matter, many scientists agree that these are some questions that ...

"When employing these approaches, it is straightforward to measure the velocity of dark matter, although experimentally this is of course difficult," said Fukuda. "For light dark matter, however, we ...

At the center of our galaxy, something incredibly heavy is pulling the strings. Stars ...

Dark matter is thought to outnumber regular matter by a factor of five to one – so why can’t we find the stuff? A new study proposes looking for it from space, using a satellite containing a ...

About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with ...

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 ...

Using NASA's Fermi telescope, researchers have detected powerful gamma–ray radiation emerging from a 'halo–like' structure surrounding the Milky Way. Its frequency and intensity suggest that this ...
