The Heart Nebula

Click image for Higher resolution version


Cosmic clouds seem to form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula’s newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are in the center of this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas.  Wider field images reveal that IC 1805’s simpler, overall outline suggests its popular name – The Heart Nebula. IC 1805 is located about 7,500 light years away toward the constellation Cassiopeia.
