About PACMAN Nebula

The Pacman Nebula (NGC 281) is a large emission nebula that lies approximately 9,200 light years away. It is also catalogued as IC 11 and Sharpless 184 (Sh2-184). It was named the Pacman Nebula for its resemblance to Pac-Man, with his dark dust lane forms the mouth.

Sh2-184 stretches 48 light years across. It is a star-forming region that contains young stars, large dark dust lanes and Bok globules. Bok globules are small, dense dark nebulae packed with material from which new stars are formed. The dark dust lane spreads unevenly across glowing clouds of hydrogen and its appearance suggests that it being sculpted by a massive star in the background, concealed by the dark clouds.

About Casseiopeia

Mythology:


An ancient constellation that is part of the story of Perseus and Andromeda. Cassiopeia was the mother of Andromeda, and because of her boasting that she was more beautiful than the sea nymphs, the Nereids, she was forced by the god Poseidon to sacrifice her daughter to the sea monster Cetus. Also as punishment the image of Cassiopeia was placed in the sky in such a way that during part of the year the queen appears upside down.
