| 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 (aka Melotte 15).
About 1.5 million years young, the cluster stars appear in this colorful skyscape, along with dark dust clouds silhouetted against glowing atomic gas.
