Sometimes the distortions are obvious, like in the Hubble image of a distant galaxycluster above.

A galaxycluster is a collection of galaxies that orbit one another bound together by gravity.
3
The textbook case is the Bullet Cluster, where one galaxycluster is seen shooting through the other.
4
In the foreground of one new image is a galaxycluster named Abell 2744, containing hundreds of galaxies.

Image: Light bends around the massive galaxycluster Abell 2218 in this image from the Hubble Space Telescope.
1
Astronomers have found the most distant clusterofgalaxies ever seen, shown at a never-before-seen stage of development.
2
Observations of the Coma clusterofgalaxies indicated to Zwicky that they were rotating too fast to be stable.
3
The black hole responsible for the blast came from a clusterofgalaxies and forged a crater that could hold 15 Milky Way galaxies.
4
This is because astronomers believe the filaments trapping the clusterofgalaxies are carrying enough gas to "feed" the black hole, enabling it to grow.
5
The Virgo Clusterofgalaxies, of which the Milky Way is a part, will hold together, as will our orbital pirouette with the Andromeda Galaxy.
1
Galaxies are usually gravitationally bound to other galaxies, creating massive galacticclusters.
2
Galacticclusters also contain some of the largest accumulations of dark matter in the universe.
3
It has become mere pantomime, as intricate and as meaningless as the space-time curves that guide galacticclusters through a measureless cosmos.
