NASA: Do these distant galaxies need guarding?

NASA has spotted some distant galaxies that may need guarding.

Released just in time for the new Guardians of the Galaxy Vol. 2 movie Thursday, this stunning image taken by the Hubble Telescope shows galaxy cluster Abell 370, which "contains a vast assortment of several hundred galaxies tied together by the mutual pull of gravity," NASA said in a statement.

The cluster's enormous gravitational influence warps the shape of spacetime around it, causing the light of background galaxies to spread out along multiple paths and appear both distorted and magnified, the European Space Agency said. The effect can be seen as a series of streaks and arcs curving around the center of the image.

The image is part of the Frontier Fields program, which has produced the deepest observations ever made of galaxy clusters. These observations are helping astronomers understand how stars and galaxies emerged out of the dark ages of the universe billions of years ago.

Abell 370 is located approximately 4 billion light-years away from Earth in the constellation Cetus.
