A planetary nebula, abbreviated as PN or plural PNe, is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. The term "planetary nebula" is a misnomer because they are unrelated to planets or exoplanets.

Planetary nebulae are relatively short-lived phenomena in astronomical terms. They last only a few tens of thousands of years. Our own Sun will follow this evolutionary pathway and become a red

The stars that form this nebula are not large enough to become supernovae so they simply shed their materials in symmetrical formations. A planetary nebula is a shell of illuminated gas surrounding certain dying stars. As a lower to medium-sized star dies, it will reignite its helium energy shell in short bursts called a thermal pulse. · Bipolar planetary nebula formation animation by Thomas Goertel (STScI) · Garden Sprinkler Nebula image courtesy of ESA, A.

A nova is a stellar explosion. A supernova is a far more cataclysmic event which happens when a massive star collapse in on itself. The name of planetary nebulae arose because of the visual similarity between some round planetary nebulae and the planets Uranus and Neptune when viewed through early telescopes. When a star with a mass up to eight times that of the Sun approaches the end of its life, it blows off its outer shells and begins to lose mass.

The term originates from the planet-like round shape of these nebulae observed by astronomers through early telescopes. Planetary nebula, any of a class of bright nebulae that are expanding shells of luminous gas expelled by dying stars. Observed telescopically, they have a relatively round compact appearance rather than the chaotic patchy shapes of other nebulae—hence their name, which was given because of their resemblance to planetary disks when viewed with the instruments of the late 1700s, when the first planetary nebulae were discovered. A planetary nebula represents a phase of stellar evolution that the sun should experience several billion years from now. When a star like the sun uses up all of the hydrogen in its core, it expands into a red giant, with a radius that increases by tens to hundreds of times. A planetary nebula is an expanding, glowing shell of hot gas (plasma) that is cast off towards the end of a low- mass star's life. Despite the name, they have nothing to do with planets, and were so named because early astronomers thought they looked a bit like planets through a small telescope.
