Description
The Heart Nebula is a large emission nebula that lies about 7,500 light years away from Earth, in the constellation of Cassiopeia. It takes its name from its resemblance to a human heart. The prominent red glow is conferred by particles of ionized hydrogen gas powered by a small group of stars near the nebula’s center.
Roughly 2.5 degrees separate the Heart Nebula from another iconic object: the Soul Nebula. The two form the “Heart & Soul” complex and are physically connected by a bridge of gas.
