Hubble telescope discovers rare galaxy that is 99% dark matter
Astronomers using the Hubble, Euclid, and Subaru telescopes have discovered one of the most dark-matter-dominated galaxies ever seen, named CDG-2, about 245 million light-years away.

The galaxy was detected through a cluster of four globular star clusters … Continue reading Hubble telescope discovers rare galaxy that is 99% dark matter
