Stars with high masses live longer than stars with lower masses. A planetary nebula is an astronomical object consisting of a glowing shell of gas and plasma formed by certain types of stars at the end of their lives. A high-mass star dies more violently than a low-mass star because: it generates more heat and its core eventually collapses very suddenly.
