This infrared image made by the NASA/ESA Hubble Space Telescope shows part of NGC 2174, the Monkey Head Nebula. The structure lies about 6400 light-years away in the constellation of Orion (The Hunter). The Hubble Space Telescope marks its 25th anniversary. A full decade in the making, Hubble rocketed into orbit on April 24, 1990, aboard space shuttle Discovery. (Photo by NASA/ESA/Hubble Heritage Team (STScI/AURA) via AP Photo)
