Astronomy Final Exam

What makes supernovas explode?

• It can happen because a chicken nugget decides it wants some sauce and it falls into a nuclear reactor and creates a supernova.

• It can happen from a Moon stealing mass from a companion star and then stealing so much it explodes into a million pickles.

• It can also happen when two neighboring galaxies collide.

• It can happen when a star comes to the end of its life and has no more nuclear energy and some mass flows to the core until it can’t withstand its own gravitational force and collapses in on itself and blows up
