Planetary Nebulae

Planetary nebula are the end stages of an average star’s life where the star is not large enough to blow up as a supernovae or collapse into a Neutron star or Black Hole. The outer layers of the dying star are thrown off then superfast winds from the hot white dwarf  remaining puff out , compress and ionise the gas to cause the glow we see as the planetary. In fact they have nothing to do with planets but was a name coined by William Herschel who likened them to a planetary disk after he had discovered Uranus.
