Using the NASA/ESA  Hubble space telescope, Astronomers have found a galaxy that appears to contain almost no dark matter. 

This discovery of the galaxy NGC 1052-DF2 challenges currently-accepted theories of  galaxy formation and provides new insights into the nature of dark matter. 

Hubble helped to accurately confirm the distance of this Galaxy to be 65 million light-years and determined its size and brightness.
It is larger than the Milky Way, but contains about 250 times fewer stars, leading it to be classified as an ultra diffuse galaxy.
