What is a planetary nebula? Rings of icy rock which form around stars prior to fusion beginning. The remains of a high-mass star that has exploded. Interstellar gas from which planets are likely to form. Gas ejected from a low-mass star in the final stage of its life. Gas created from the remains of planets that once orbited a dead star.
