A large bruise on Jupiter was discovered by an amateur stargazer – Australian Anthony Wesley. The mystery around the dark spot has been solved – it was caused by rogue asteroid and the collision would have been equal to several thousand nuclear bombs.

Australian Anthony Wesley was using a home-made telescope in the yard of his rural home in Murrumbateman, near Canberra, when he spotted the dark scar last year.

Mr Wesley said that he had discovered the scar in between running inside to watch the final rounds of the British Open golf on television.

‘I couldn’t believe it. I thought “That wasn’t there before” and then I realised Jupiter had actually been hit by something,’ he said at the time.
