The planetary nebula, NGC 246, is 1,600 light-years away in the constellation Cetus. Appropriately named, "the Skull Nebula" it was formed by expelled gasses of the outer atmosphere of a once sun-like star. The central star is the fainter of a binary system and is entering its final phase of becoming a white dwarf
