Supernovae: The Most Extreme Explosions!

Supernovae are some of the brightest and most powerful explosions in the universe, bright enough to outshine entire galaxies. These cosmic catastrophes come in many varieties, characterised by their elements and light. Today, we will cover the various types of supernova as we take a deep dive into these tremendous explosions. Do you use these videos to sleep or for night time watching?
