Biggest solar flare goes off

The Sun has just released the biggest flare ever seen –

It was so energetic that it overloaded the detectors on satellites monitoring the Sun’s surface.

The blast was accompanied with a gigantic gas cloud of billions of tonnes of superhot gas being ejected into space – some of it directed at Earth.

Researchers are saying that the Sun’s current spate of activity – now 10 days in duration – is the most dramatic and intense ever witnessed on the Sun’s surface.
