The scientists described in the journal Nature how they gathered images of the exploding stars by monitoring the same galaxies over five years.More info at BBC News/a>.
They used multiple images to pick out supernovae in the distant Universe. The furthest two supernovae the team found occurred about 11 billion years ago.
Mark Sullivan, an astronomer from the University of Oxford in the UK, was one of the authors of the study. He explained that these stars exploded about 2.5 billion years after the Big Bang.
