About This Photograph
The Horse Head Nebula is one of the most famous of deep-sky objects. Located in the same interstellar cloud as the Great Orion Nebula, this intriguing puff of gas and dust silhouettes the bright curtain of energized hydrogen gas beyond. Were it not for this backdrop, the Horse Head would very likely be impossible to discern.
