Supersize!

The giant elliptical galaxy in the center of this Hubble Space Telescope image is the most massive and brightest member of the galaxy cluster Abell 2261. It’s more than a million light-years across; that’s about ten times the diameter of our Milky Way galaxy. The bloated galaxy is a member of an unusual class of galaxies that have diffuse cores filled with fogs of starlight. Abell 2261 is three billion light-years away.
