About The Heart Nebula
About The Heart Nebula
The Heart Nebula (IC 1805) is an emission nebula located at an approximate distance of 7,500 light years from Earth, in the constellation Cassiopeia. It is also known as Sharpless 2-190 (Sh2-190) or the Running Dog Nebula because, when seen through a telescope, it looks a bit like a running dog. The nebula has an apparent magnitude of 18.3 and an absolute magnitude of 6.5. It is 150 arcminutes in size and known for its intensely red glowing gas and dark dust lanes forming a shape that resembles a heart symbol.
The Heart Nebula is formed by plasma of ionized hydrogen and free electrons.

Mythology:
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.
