Description:
Among the most photographed and examined areas of the sky is this region surrounding Alnilak, one of the three bright stars in the Belt of Orion.
The Horsehead Nebula: The famous Horsehead Nebula, which was first photographed and identified in 1888 by Scottish astronomer Williamina Fleming at the Harvard Observatory, is a foreground cloud of dark gas that is seen in silhouette against a background red hydrogen gas cloud.

The Zeta Orionis (Flame) Nebula: The large, intricate pale pink nebula to the lower right of the brightest star is the Flame Nebula (NGC 2024), which is located between 900 and 1,500 light years from our solar system.
