WebThe planetary nebula phase is a final stage in a low-mass star's life. During this phase, the star sheds its outer layers. This creates an expanding, glowing shell of very hot gas. ... Low-mass stars turn into planetary nebulae towards the end of their red giant phase. At that point the star becomes highly unstable and starts to pulsate. WebStudents may think all stars end their lives in the same way — as superno-vae. Whether a star becomes a planetary nebula or a supernova depends on its original mass. The Sun …
WebOct 8, 2024 · The outer layers of a star are expelled as the core collapses around them. A planetary Nebula is made up of layers that are made up of planet molecules.
