Title: Heart Nebula (IC 1805/Sh2-190) and Fishhead Nebula (IC 1795)

Description: The large emission nebula dubbed IC 1805 looks, in whole, like a heart. The nebula's glow, as well as the shape of the gas and dust clouds, is powered by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster Melotte 15. This cosmic heart is found in the constellation of Cassiopeia.

To some, the nebula near the Heart Nebula looks like the head of a fish. It features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia. It is part of a complex of star forming regions that lie at the edge of a large molecular cloud.
