Do dwarf galaxies have black holes?

They have identified 13 dwarf galaxies that host very massive black holes. These galaxies, more than 100 times less massive than our own Milky Way, are among the smallest galaxies known to host massive black holes. In roughly half of these galaxies, the black hole is not at the center of the galaxy.

Which is the biggest universe?

A new report in 2014 confirms the Milky Way as a member of the Laniakea Supercluster. The Caelum Supercluster is a collection of over 550,000 galaxies. It is the largest of all galaxy superclusters.
