This Hubble Space Telescope image shows the iconic Horsehead Nebula in a new light, as seen in infrared wavelengths. The nebula normally appears as a dark shadow in optical light. but in infrared, it appears transparent and ethereal. The rich tapestry of the Horsehead Nebula pops out against the backdrop of Milky Way stars and distant galaxies that are easily seen in infrared light. The Horsehead Nebula is a favorite target for amateur and professional astronomers. It is located in the constellation Orion, about 1,500 light-years from Earth.
