"The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy."
The Heart Nebula, IC 1805, an emission nebula, lies some 7500 light years away from Earth. It is located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This nebula is formed by plasma of ionized hydrogen (HII) and free electrons.
