A Supernova Explosion in Process. A supernova occurs when a super massive star explodes. It is a dramatic end to a starâs life. Supernovae (which is the plural form of supernova) become very bright and cause an enormous burst of radiation that can outshine an entire galaxy before disappearing.
Through supernova explosion: Some nebulae form by way of supernova explosions, caused by the collapse of massive, short-lived stars. The materials thrown off from the gigantic explosion are known as supernova remnants. Example: Crab Nebula. Through shedding off the outer layers of a low mass star: Other nebulae form as planetary nebulae. This is the final stage of a low-mass star's life, like our Sun. Such stars evolve into red giants and then blow off their outer layers of gas. These stars do not have enough mass to go supernova. Example: Ring Nebula.
