The ExTrA telescopes at ESO's La Silla Observatory in Chile will be used to locate and analyze Earth-size planets orbiting nearby red dwarf stars. ExTrA's new design allows for greater sensitivity compared to previous searches. In this nighttime image, the ExTrA three domes are seen under a beautiful sky featuring the constellation Orion (the Hunter) and the Pleiades star cluster.
