B33, the Horsehead Nebula, is at lower left. M42, the Great Nebula in Orion, is at upper right.

This amazing area of sky is located in the constellation of Orion. Beautiful swirling clouds of dust and gas form bright and dark nebulae. These areas are stellar nurseries where stars form when the clouds condense under the influence of gravity.

The Horsehead is a dark nebula that is located 1,500 light-years away.

The Orion nebula is a complex of red emission nebulae that is located at a distance of 1,300 light-years.

Both the Horsehead Nebula and Orion Nebula are part of the much larger Orion Molecular Cloud.

North is to the left in the above image.
