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.

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.

Astronomers have discovered a nearly invisible galaxy called CDG-2, which blends into the cosmic background and is made up of 99% dark matter. Unlike bright galaxies like the Milky Way, CDG-2 barely ...

A team of astronomers has identified an extremely faint galaxy called CDG-2, located roughly 300 million light-years from Earth, where an estimated 99% of its total mass is made of invisible dark ...

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

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 ...

Take some cosmic dust and gas, then add billions and billions of planets and a whole lot of stars to the mix. Spice it all up ...

Globular clusters are ancient, spherical groups of stars that are often as old as the galaxies they orbit. The stars in a globular cluster orbit the center of mass of the cluster, and the angular ...

The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion years old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led ...

It seems like the only things I have seen in the evening sky recently have been clouds. Although the garden plants are happy with the rain, my dogs are unhappy about the thunder. Whenever the sky does ...
