White Dwarfs & Planetary Nebulae

Phil Plait discusses the fate of low mass stars, focusing on white dwarfs and planetary nebulae. White dwarfs are dense, hot remnants of stars, while planetary nebulae are beautiful, short-lived structures formed by expelled gas illuminated by the white dwarf. The video explores the formation, characteristics, and diverse shapes of these nebulae, influenced by factors like binary stars and swallowed planets. The sun is unlikely to form a planetary nebula, but more massive stars do. The episode concludes with a look at the sun's quiet end and a teaser for the next topic on massive star explosions.
