Astronomers have found the most distant clusterofgalaxies ever seen, shown at a never-before-seen stage of development.

Observations of the Coma clusterofgalaxies indicated to Zwicky that they were rotating too fast to be stable.

The black hole responsible for the blast came from a clusterofgalaxies and forged a crater that could hold 15 Milky Way galaxies.

This is because astronomers believe the filaments trapping the clusterofgalaxies are carrying enough gas to "feed" the black hole, enabling it to grow.

The Virgo Clusterofgalaxies, of which the Milky Way is a part, will hold together, as will our orbital pirouette with the Andromeda Galaxy.
