This picture shows the Horsehead Nebula and the Orion Nebula. These two nebulas both lie 1,500 light-years away in the constellation Orion. The Horsehead nebula looks like a dark cloud. The star Alnitak is the easternmost star in Orion's belt and it is also pictured here to the left of the Horsehead. Below Alnitak and to the left of the Horsehead is the Flame Nebula. To the right of the picture is the M42 or the Orion Nebula. The Orion Nebula is an emission region. Next to the Orion nebula is the bluish reflection nebula.
