Galaxies and dark matter go together like peanut butter and jelly.

Rarely is one without the other, but a recently discovered galaxy called NGC 1052-DF2 is nearly entirely lacking in dark matter.

NASA's Hubble Space Telescope took an image of a bizarre, ghostly looking galaxy called NGC 1052-DF2 that astronomers calculate to have little to no dark matter.

This is the first galaxy astronomers have discovered to be so lacking in dark matter, which is thought to comprise 85% of our universe's mass.
