"We pointed the telescope at Messier 82 - it's quite a bright galaxy, quite photogenic. But as soon as it came up on screen, it didn't look right to me," Dr Fossey told BBC News. | "We pointed the telescope at Messier 82 - it's quite a bright galaxy, quite photogenic.

The "fluke" discovery led to a global scramble to acquire confirming images and spectra from the dazzling object. | The "fluke" discovery led to a global scramble to acquire confirming images and spectra from the dazzling object. |
It has now been confirmed by the International Astronomical Union as a supernova - a violent blast of energy and light that is hurled out as a star dies. | |
It has taken 12 million years for the light to reach us. But though this may seem like a long way away, scientists say this is the closest supernova to be spotted since SN1987A in the Large Magellanic Cloud and SN1993J in Messier 81. | |
Scientists says it could grow even brighter over the coming weeks, before fading away. | Scientists says it could grow even brighter over the coming weeks, before fading away. |
If this happens, astronomers in the northern hemisphere may be able to spot it with binoculars, by looking between the Great Bear and the Little Bear. | If this happens, astronomers in the northern hemisphere may be able to spot it with binoculars, by looking between the Great Bear and the Little Bear. |
