A supernova occurs when a massive star exhausts its nuclear fuel and undergoes gravitational collapse.
There are two main types of supernovae: Type I (lack hydrogen lines) and Type II (show hydrogen lines).
Supernovae are major sources of heavy elements in the universe, dispersing them into the interstellar medium.
The remnants of supernovae can form neutron stars or black holes depending on the mass of the original star.
Supernova explosions are primary sources of cosmic rays, which travel through space at nearly the speed of light.
