The Heart Nebula (IC 1805, sh2-190) is a large emission nebula located in constellation Cassiopeia in the Perseus Arm of Milky Way Galaxy at an approximate distance of 7,500 light years from Earth. This giant gaseous cloud glows by ionization from intense UV radiation emitted by bright-blue supergiant young stars from the open cluster Melotte 15 near the nebula's center. Stellar winds of charged particles flows outward from the newborn stars by pushing its clouds of dust and gas and has sculpted the nebula in a shape that resembles a human heart. Clouds of interstellar dust create a dark silhouette in the center of the bright nebula.
