Supernovae: The Stars That Die to Build the Universe

Explore the explosive science of supernovae, the spectacular deaths of massive stars that light up galaxies and forge many of the elements that make planets, life, and us possible. In this Deep Dive, we unpack how stars reach their dramatic final moments, what triggers different types of supernova explosions, how shockwaves spread through space, and why these cosmic catastrophes are essential to the evolution of the universe. From stellar cores collapsing under gravity to the creation of neutron stars, black holes, and heavy elements, this episode turns one of astronomy’s most powerful events into a clear, engaging journey through the physics of stellar death and cosmic rebirth.
