The discovery of CDG-2 began when a team of astronomers investigated tight groupings of stars called globular clusters, which ...

NASA said CDG-2 “may be among the most heavily dark matter-dominated galaxies ever discovered” ...

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.

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.

Scientists using a trio of some of the world’s most powerful observatories, the Hubble Space Telescope, ESA’s Euclid, and the Subaru Telescope, have pulled back the curtain on a ghost galaxy that is ...

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

Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster ...

Astronomers working with NASA’s James Webb Space Telescope have produced the sharpest wide-area map of dark matter ever ...

A galaxy so faint it escaped detection for as long as anyone has been scanning the sky has finally been found. Called CDG-2, this newly identified “ghostly” galaxy may be one of the most dark ...

In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark ...

Humanity has always been fascinated by space. We are able to see the universe with breathtaking clarity because of NASA's powerful telescopes. Astronomers have been able to take pictures of galaxies ...
