Got these straight from very sus web pages, just for you.
Elements like carbon, iron, silicon, nitrogen and oxygen that we find on Earth actually came from a supernova.
During the explosion, elements like uranium and gold are formed because of the extremely high temperature (millions of degrees) caused by the explosion.
In 1054 AD, Islamic and Chinese astronomers observed and documented a supernova. It was so bright that it was visible in broad daylight.
