Can a supernova out shine an entire galaxy?
Well can it?
Well yeah it can. A single supernova explosion can actually out shine a galaxy meaning the explosion can be really bright and is brighter than the galaxy. It is almost like it blinds the entire galaxy.
but how does it explode? many of you are probably wondering
•Gravity creates a temperatures and pressure fusion proceeds to get heavier and heavier with iron which remains in the center of the star, in a moment all light cores are burnt out and gravity wins over the power of fusion reactions, which are now absent. The stars core turns into a high density object which may differ depending on the star mass. Then the top layer of the star explodes, leaving a very bright glow.
