IC1805 - "Heart Nebula" in Cassiopeia

For obvious reasons, IC 1805 (Sh2-190) is commonly known as the Heart Nebula. It lies approximately 7500 light years away in the constellation of Cassiopeia. This is an emission nebula, glowing red due to ionization of the hydrogen by young stars within it. It spans about 200 light years and covers 2.5 degrees of the sky. The predominant cluster of stars at its center is known as Melotte 15.
