Supernovae: A Primer

Supernovae are powerful explosions that occur at the end of the lives of massive stars. They are one of the most energetic events in the universe, and they can release more energy than a trillion suns. Supernovae are responsible for creating many of the elements that we see around us, including the oxygen we breathe and the iron in our blood.

Supernovae are classified into two main types:

Type Ia supernovae: These supernovae occur when a white dwarf star accretes matter from a companion star until it reaches a critical mass and explodes.
Type II supernovae: These supernovae occur when a massive star runs out of fuel and collapses under its own gravity, causing an explosion.

Supernovae are important objects of study because they provide us with information about the evolution of stars and galaxies. They also play a key role in the chemical enrichment of the universe.
