Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by a once-in-a-generation “space storm”, Nasa has warned.

National power grids could overheat and air travel severely disrupted while electronic items, navigation devices and major satellites could stop working after the Sun reaches its maximum power in a few years.

Senior space agency scientists believe the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013.

The National Risk Register, established in 2008 to identify different dangers to Britain, also has “comprehensive” plans on how to handle a complete outage of electricity supplies.
