The solar flares and sunspots throw massive clouds of electrically charged gas at the Earth which cause power surges and throw compasses into disarray.

The last really big solar "super flare" – in 1859 – knocked out telegrams and ship's compasses and covered two-thirds of the Earth in a blood red aurora.

"A major objective is to shed light on the impact of both everyday and extreme space weather on our technologies and therefore to be better aware of the risk.”

The model developed by the British team, the most sophisticated yet developed, takes magnetic field measurements from all over the UK and sees how they affect the National Grid.

The US National Academies estimate the cost of a future severe space storm hitting the USA to be up to £1.5 trillion in the first year.

They believe that full recovery could then take 4-10 years.
