One of the most photographed regions of space, the equine silhouette of the Horsehead Nebula (B 33), its surrounding nebula (IC 434) and the Flame Nebula (NGC 2024).
Part of the larger Orion Molecular Cloud Complex, the hydrogen gas emits vivid red light in a process of ionising radiation from the nearby star.
The Flame Nebula is an emission nebula about 1200 light years away from Earth.
