The '''Heart Nebula''', '''IC 1805''', lies some 7500 light years away from [[Earth]] and is located in the [[Perseus]] arm of the [[Milky Way 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 right) is separately classified as [[NGC 896]], because it was the first part of this nebula to be discovered.
The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This [[open cluster]] of stars known as [[Melotte 15]] contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. The cluster used to contain a microquasar that was expelled millions of years ago.
