The Horsehead Nebula, also known as Barnard 33, is 1600 light-years away in the Orion constellation.
This is a dark nebula. It is visible only because of the lighting around it. This molecular cloud has the particularity of resembling a horse’s head, when it is observed from Earth. This nebula is recorded for the first time in 1888 by the astronomer Williamina FLEMING (1857-1911).
The Horsehead Nebula is revealed during photoshots with long exposure times, which explains the almost impossibility of observing it without going through photography, despite an imposing size of nearly two light years (about twenty thousand billion kilometers). It decreases gradually under the effect of ultraviolet rays.
