B33 in IC434 – Horsehead Nebula
The Horsehead Nebula (Barnard 33) is a dark nebula located near the star Alnitak which is the easternmost star in the belt of Orion. The constellation Orion is very prominent in he winter evening sky.
The nebula lies at approximately 1500 light years from Earth, and is approximately 3.5 light years wide. A lot of star formation is taking place in this region. The red glow comes from hydrogen gas mostly behind the nebula which is ionized by the bright star Sigma Orionis.
The darkness of the Horsehead is caused mostly by thick dust.
Bright spots in the Horsehead Nebula’s base are young stars which are in the process of forming.
