Abell 8
Description By Sakib Rasool
Abell 8 is a 1 arcminute planetary nebula in the constellation of Auriga that consists of a Ha bright rim and an OIII interior. Deep narrowband images such as this one show extended clouds of hydrogen in the vicinity. This isn't material ejected by the progenitor star but ambient material in the surrounding interstellar medium (ISM) that is being ionized by ultraviolet radiation of the central star leaking out of the thin gaseous shell of the planetary nebula. Abell 8 was discovered by the astronomer George Abell in 1955.
