Cosmic clouds form strange 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 scattered in the top right corner of this picture, along with dark dust clouds in silhouette against glowing atomic gas. In this composite of narrowband images, the view spans about 30 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. The Heart Nebula. IC 1805 is located about 7,500 light years away toward the constellation Cassiopeia.
