Barnard 33 the Horsehead nebula


Barnard 33, the Horsehead nebula, is a dark nebula located in IC 434, an emission nebula in Orion located about 1,500 light years from Earth. Dark nebula is an area of dense, thick dust, and from Earth, has the appearance of a horse's head. The pink nebula is IC 434, an emission nebula. The pinkish glow originates from hydrogen gas behind the nebula, which is ionized by the nearby bright star Sigma Orionis.
