Explanation:
The Heart Nebula, IC 1805 (SH2-190) is an emission nebula in the constellation Cassiopeia.
The nebula is formed by plasma of ionized hydrogen. The knot in the upper right is separately
classified as NGC 896 and was discovered first. The radiation of a small group of stars near
the nebulae's center, known as Melotte 15, drives the intense red output.
The colors are mapped as real colors:
light red = H-alpha
cyan = OIII
dark red = SII
