The Horsehead Nebula rears its pretty head in a November 17 photograph submitted to National Geographic's Your Shot photo community.
Taken from the New Forest Observatory in the United Kingdom, the image shows how the nebula's horse head is part of a larger cloud of dust. Situated about 1,500 light-years away, the Horsehead Nebula is visible only because its obscuring dust is silhouetted against another, brighter nebula, according to NASA.
