The Wide Field Imager (WFI) on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile captured this view of dark cloud Lupus 4 blotting out background stars. Lupus 4 is a dense pocket of gas and dust where new stars are expected to form. The cloud is located about 400 light-years away from Earth. - Credit: ESO
M44: The Beehive Cluster A mere 600 lys away, M44 is one of the closest star clusters to our solar system. Its stars are young though, about 600 my old compared to our Sun's 4.5 by. Based on similar ages and motion through space, M44 and the even closer Hyades star cluster in Taurus are thought to have been born together in the same large molecular cloud. Visible to the unaided eye, M44 has been recognized since antiquity.
