Dotted across the sky in the constellation of Pictor (the Painter’s Easel) is the galaxy cluster highlighted here by the NASA/ESA Hubble Space Telescope: SPT-CL J0615-5746, or SPT0615 for short.";

Galaxy Clusters happen when gravity pulls galaxies together into groups. They are helping scientists get a look at some of the oldest places in the universe. Idaho Matters talks to one astrophysicist about how these clusters are formed and why they are important to Earthlings. Find out more here.
