Flame and Horsehead Nebula

The Flame Nebula (NGC 2024; Sh2-227) and Horsehead Nebula (IC 434; B33) are part of the Orion Molecular Cloud. They lay approximately 1500 light years away.

The Flame Nebula consists of ionized Hydrogen that is caused by the extreme ultraviolet light emitted by the bright star Alnitak. This is the easternmost star in Orion's belt. Dust lanes in front of the nebula give it its characteristic appearance.

The Horsehead Nebula is a dark nebula. It is simply a cloud of dust that is visible due to its obstruction of the background glow.

The blue reflection nebula to the lower left of the Horsehead is designated as NGC 2023.
