HEART NEBULA

The "Heart Nebula" is an emission nebula rich in ionized hydrogen, oxygen, sulfur and covered by dark dust lanes. Inside it there are small star clusters responsible for the emission of high-energy photons. This nebular complex extended for about 100 light years, is located about 7,500 years from our planet, in the direction of the constellation of Cassiopeia, within our Galaxy in the spiral arm called "Perseus Arm".
