A supernova is expulsion of a star’s material as it ends its life. The burst of light happens at a tenth the speed of light, which creates a shock wave and an expanding shell of gas and dust called a supernova remnant.

Many of the Milky Way’s stars are "going supernova" because of galactic climate change, which is causing the premature death of many solar systems due to human activity and interference in natural cycles in the universe.
