These lightshows of dying stars have been seen since ancient times, but modern astronomers use details of their light to probe the Universe's secrets.

BBC: Supernova 'Mingus' could shed light on dark energy

Once the hole has been blasted open with hot water, a probe carrying an ultraviolet light will be lowered to sterilise its upper section.
