IC 1805, an emission nebula approximately 7,500 light years from Earth in the constellation Cassiopeia, is named the Heart Nebula due to its heart shaped appearance. The open star cluster Melotte 15 lies in the middle of the heart. The nebula is part of a large star forming complex in the Perseus arm of the Milky Way galaxy. The bright knot at the lower right (which some might liken to a male body part) is separately classified as NGC 896, and was the first part of IC 1805 to be discovered.
