Notes
This bright nebula in eastern Cassiopeia is illuminated by the light of the cluster Melotte 15, deep within its clouds of nebulosity. The Heart Nebula is one of a pair of similar nebulae in the same part of the sky, and the other, formally designated IC 1848, is popularly known as the Soul Nebula (so the entire structure is the 'Heart and Soul').
