NGC281, the Pacman Nebula
Object type:
Emission and dark nebula complex

Constellation: Cassiopeia
NGC281 is a great star forming region in the constellation of Cassiopeia. Its interesting shape is a result of interaction between red-glowing emission nebula and dark lanes of interstellar dust and gas obscuring it. In the middle of the nebula there is a very young open cluster IC1590. Stars of that cluster were formed inside of NGC281 and are responsible for ionization and glow of gas in the nebula. In the nebula several Bok globules are visible. Bok globules are dark clouds of dense dust and gas in which star formation takes place. NGC281 is 10 kly distant from us and it has diameter of 80 ly.
