TED-Ed: How to detect a supernova - Samantha Kuula

The video explains the occurrence and observation challenges of supernovae, highlighting that while supernovae happen frequently in the universe, observing them from Earth is difficult due to the need for precise timing and location. Neutrinos, which travel faster than light in a supernova context, can provide early warnings of these cosmic events. The video details the two types of supernovae, Type 1 and Type 2, and their energy and matter outputs, including the formation of heavy elements. The Supernova Early Warning System (SNEWS) uses neutrino detection to alert astronomers to imminent supernovae, allowing for timely observation.

What is the average frequency of supernovae occurring in a galaxy like the Milky Way?
