There will be a once-in-a-lifetime event in the night sky over the next few days – as a star exploding 21 million light years away becomes so bright it will be visible through binoculars across Britain.
The supernova is predicted to reach its brightest between September 9 and 12, and will be the brightest since 1954, visible all over Britain, weather permitting. A team of scientists at Oxford University are tracking it using the Hubble Space Telescope.
The explosion is so bright because the star is very close to Earth, cosmically speaking, in the Big Dipper constellation, Ursa Major. Most supernovae are more than 1 billion light years away.
This photo of the supernova was released on September 7 - over the next few nights, the flare will be visible to amateur sky watchers as a pale blue light. This image was created using several filters from the ultra-violet to the infra-red
Dr Mark Sullivan, the astrophysicist leading the Oxford team examining the supernova, designated PTF-11kly, said: ‘This is accessible to anyone with a decent pair of binoculars. For many it could be a once in a lifetime chance to see a supernova blossom and then fade before their eyes. We may not see another like it for over 100 years.’
