A closer look into the Virgo cluster

NASA today posted this image of the Virgo cluster of galaxies, the closest to our own Milky Way Galaxy.

The Virgo cluster’s heart is about 70 million light years away from us. The whole cluster contains more than 2,000 galaxies, and has a noticeable gravitational pull on the galaxies surrounding the Milky Way.

The cluster contains not only galaxies filled with stars but also gas so hot it glows in X-rays.

Motions of galaxies in and around clusters indicate that they contain more dark matter than any visible matter we can see.
