IC1805 Heart Nebula in Cassiopiea

IC1805 is part of a large complex of nebulosity in the constellation of Cassiopeia. The name Heart Nebula clearly comes from its shape. It is about 7500 light years away. The open cluster of stars in the centre is catalogued as Melotte 15. The red colour of the Heart Nebula is driven by the radiation from Melotte 15. This cluster contains a few bright stars nearly 50 times the mass of our Sun.
