Horsehead Nebula

The Horsehead Nebula is a dense cloud of gas and dust embedded in a much larger structure, and a favorite target of astrophotographers because of its unusual shape. Most previous views have been almost identical. But when seen in infrared light, it takes on a whole new appearance. Strikingly, it is nearly a negative of the visible-light view. The area above the top of the horse is bright in visible but dark in infrared, while the body of the horse shows up much brighter in the infrared compared to the visible. Learn more
