NGC 7027

NGC 7027 is a very young and dense planetary nebula about 3,000 light-years from Earth in the constellation Cygnus Only a few hundred years old, it’s a tiny infant. Indeed, it’s one of the smallest planetary nebulae, only 0.2 by 0.1 light-year. Most planetary nebulae are around 1 light-year across. NGC 7027 has a very complex structure, consisting of inner elliptical region of ionized gas inside of a large cloud of neutral gas.

The white dwarf at the core of the nebula has a mass about 70 percent of the Sun’s. The expanding halo has roughly three times the mass of the Sun.
