The Heart Nebula, IC 1805, Sh2-190, 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 lower left)
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. (WIKI)
