What type of nebula results from the catastrophic death of a star much more massive than the Sun?
Answer
Supernova remnant nebula
The end stages of massive stars lead to the most violent events in the cosmos. When stars significantly exceeding the mass of our Sun exhaust their fuel, they collapse and explode in a supernova event. This explosion violently ejects the star's outer layers, which contain elements forged during its lifetime, outward at immense speeds. The subsequent expanding shockwave and heated material define what is known as a supernova remnant nebula, which is crucial for dispersing heavy elements like carbon, oxygen, and iron throughout the interstellar medium for subsequent cosmic generations.
