About this Image

The Heart Nebula, IC 1805 or Sharpless 2-190, lies some 7500 light-years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons.
The very brightest part of this nebula (the knot at the top-right) is separately classified as NGC 896, because it was the first part of this nebula to be discovered.
