In 2018, a team of astronomers from the United States and Canada discovered that an ultra-diffuse galaxy called NGC 1052-DF2 (DF2 for short) contains virtually no dark matter. The galaxy is roughly the size of our Milky Way Galaxy, but hosts only 1/200 the number of stars. It lies in the constellation of Cetus, about 65 million light-years away, and is a member of the NGC 1052 group of galaxies. Now, the team reports the discovery of a second galaxy in this class, residing in the same group.
