The Heart Nebula (also IC 1805 or Sharpless 2-190) lies about 7,500 light years away from Earth and is located in the Perseus arm of our galaxy in the constellation Cassiopeia. It was discovered by William Herschel in 1787. The Heart Nebula is a large emission nebula with glowing, ionized hydrogen gas and embedded, darker dust lanes. The brightest part of the nebula (the node at the western edge) is separately classified as NGC 896, as it was the first part of the nebula to be discovered.
The intense red of the nebula and its appearance are caused by the radiation of a small group of stars near the center of the nebula. This open cluster of stars, known as Melotte 15, contains a few very bright stars almost 50 times the size of our sun.
