Explanation: Cosmic clouds seem to form
fantastic shapes in the central regions of emission nebula IC 1805. Of course, 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 toward the right in this
colorful skyscape, along with dark
dust clouds in silhouette against glowing
atomic gas. A composite of narrow and broad band telescopic images, the view spans about 30 light-years and includes emission from hydrogen in green, sulfur in red, and oxygen in blue hues.
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.
