Distant Galaxies (a) The young cluster of galaxies MS1054-03, shown on the left, contains many orbiting pairs of galaxies, as well as remnants of recent galaxy collisions. Several of these systems are shown at the right. This cluster is located 8 billion light-years away from Earth. (b) This image of more than 300 spiral, elliptical, and irregular galaxies contains a galaxy that is an estimated 13.2 billion light-years from Earth. A compact galaxy of blue stars that existed 480 million years after the Big Bang is shown in the images on the right.
