A star one million times brighter than our own sun has exploded, taking the science community completely by surprise.
Physicists were stumped when the star, 200million light years from Earth, erupted into a super-sized supernova in 2005. The spectacular event was captured by Nasa's Hubble Space Telescope.
Researchers from the Weizmann Institute and San Diego State University said it was the largest exploding star ever observed.
