First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists conjectured that the missing mass in the universe was made up of small ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ ...

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-scale distribution of ...

Dark galaxies are believed to have very few stars, if any at all, according to CNN. In the case of CDG-2, a preliminary ...

“The Euclid data clearly confirm the presence of the extremely faint, diffuse light of CDG-2, revealing the galaxy behind the ...

Astronomers have spotted a galaxy so faint, it’s almost invisible — a discovery that could help illuminate one of the most ...

Astronomers discovered a dim, nearly undetectable galaxy which exists as a dark matter-dominated celestial body through their ...

One third of the galaxy’s entire stellar output is locked away in just a few dense balls of stars. The rest is just a thin, cold “field” of stars barely clinging to existence. It is, for all intents ...

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

Astronomers have detected a ghostly galaxy that is almost completely made of dark matter. The faint object was revealed by just four globular star clusters hiding in the Perseus cluster.

Using data from the Hubble Space Telescope, ESA’s Euclid space observatory, and Hawaii’s Subaru Telescope, the researchers discovered faint light emitting around the clusters. That light was clear ...
