Heart and Soul nebulae, optical image. The Heart nebula (IC 1805) is at upper right, with the Soul nebula (IC 1848) at lower left. Both lie around 6000 light years from Earth in the constellation Cassiopeia. The nebulae are part of the same huge complex of dust and gas, which spans around 300 light years. They glow red as the hydrogen they contain is ionised by radiation from hot young stars that formed within them.
