Astronomers discover galaxy CDG-2 that's 99% dark matter using Hubble, Euclid, and Subaru telescopes working together to detect this cosmic ghost 300 million light-years away.

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

Called CDG-2, this newly identified “ghostly” galaxy may be one of the most dark matter-dominated galaxies ever discovered, with a staggering 99% of its total mass made up of dark matter — a ...

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 ...

Astronomers have discovered a nearly invisible galaxy called CDG-2, which blends into the cosmic background and is made up of ...

Using the Hubble Space Telescope, astronomers have discovered what seems to be a galaxy that is the most heavily dominated by ...

A tight clump of four star clusters sits in the Perseus galaxy cluster, and at first glance it looks like nothing special. No bright spiral arms.

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 ...

In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies ...

It's 99 percent dark matter, a new study explains.
