An Orion Classic: The Horsehead Nebula

The Horsehead Nebula (Barnard 33) is around 1,500 light years from Earth and is located in the constellation of Orion. Due to its recognizable shape the Horsehead Nebula is one of the most famous celestial objects. It is categorized as a dark nebula composed mainly of hydrogen gas and high levels of dust blocking out background light. The dark Horsehead Nebula is visible due to the backdrop of the bright emission nebula IC 434. Both the Horsehead Nubula and IC 434 are part of the Orion Molecular Cloud Complex, an enormous star forming region spanning hundreds of light years in diameter. The Horsehead Nebula is around 3 to 4 light years tall and 2 to 3 light years across.
