A supernova can shine as brightly as an entire galaxy of billions of "normal" stars. Some of these explosions completely destroy the star, while others leave behind either a super-dense neutron star or a black hole -- an object with such powerful gravity that not even light can escape from it.
What is left behind from a supernova?
Supernova remnant, nebula left behind after a supernova, a spectacular explosion in which a star ejects most of its mass in a violently expanding cloud of debris.
What do supernovae create?
Supernovae are so powerful they create new atomic nuclei. As a massive star collapses, it produces a shockwave that can induce fusion reactions in the star's outer shell. These fusion reactions create new atomic nuclei in a process called nucleosynthesis.
