Wow ! Each of the colored dots in this new image from the Herschel telescope is a galaxy containing billions of stars. These are distant luminous infrared galaxies, and appear as they did 10–12 billion years ago, packed together like grains of sand on a beach, forming large clusters of galaxies by the force of their mutual gravity.
