Dense core of the Orion Nebula ~ About three million years old, the Orion Nebula was even more compact in its younger years and runaway stellar collisions long ago formed a black hole with more than 100 times the mass of the Sun. The Orion Nebula's distance of some 1,500 light-years would make it the closest known black hole to planet Earth.
IC 1805: The Heart Distance: 7,500 Light Years 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 nebula’s intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula’s
