Brand new supernova

The Beeb reports that a new supernova was spotted by astronomers at Oxford University, and it’s only 21 light years away (which is 9.461×10^12 km – still quite a distance at human scales).

A supernova, for those who don’t know, is a star that has exploded and is briefly more luminous than a galaxy (only for a few weeks or months). Over this brief lifetime, they can radiate more energy than the sun will over it’s entire lifetime. They can also be a prime source of elements heavier than oxygen because, like all stars, they undergo nuclear fusion. One may even have triggered the formation of our solar system.
