| IC 1805 (or Sh2-190, Heart Nebula) is an emission nebula in the constellation Cassiopeia. It is a mix of glowing interstellar gas and dark dust clouds. Derived from its shape, its nickname is Heart Nebula. It is at about 7,500 light-years away in the Perseus spiral arm of our galaxy. It is a huge star nursery. Near the center of IC 1805 there are the massive hot stars of a newborn star cluster, which is known as Melotte 15. The age of the stars in the cluster is estimated to about 1.5 million years. This view of the region around the Heart Nebula is cropped from a larger CCD image, which can be seen here: |
