Description

The Heart Nebula (IC 1805, Sh2-190) is an emission nebula in Cassiopeia and is located about 7500 light years away in the Perseus Arm of the Milky Way.  It was discovered by William Herschel in 1787.  The brightest part of the nebula is a knot on the western edge classified as NGC 896 - at the mouth of the Fish Head Nebula shown at the bottom of the image.  Much of the nebula is energized by the open cluster Melotte 15 at its center which contains several stars more than 50 times the mass of our Sun.
