Nasa warns solar flares from 'huge space storm' will cause devastation

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 Daily Telegraph can disclose.


In a new warning, Nasa said the super storm would hit like “a bolt of lightning” and could cause catastrophic consequences for the world’s health, emergency services and national security unless precautions are taken.

Scientists believe it could damage everything from emergency services’ systems, hospital equipment, banking systems and air traffic control devices, through to “everyday” items such as home computers, iPods and Sat Navs.

Due to humans’ heavy reliance on electronic devices, which are sensitive to magnetic energy, the storm could leave a multi-billion pound damage bill and “potentially devastating” problems for governments.

“We know it is coming but we don’t know how bad it is going to be,” said Dr Richard Fisher, the director of Nasa's Heliophysics division.

“It will disrupt communication devices such as satellites and car navigations, air travel, the banking system, our computers, everything that is electronic. It will cause major problems for the world.

“Large areas will be without electricity power and to repair that damage will be hard as that takes time.”

In an interview with The Daily Telegraph, he added: “Systems will just not work. The flares change the magnetic field on the earth that is rapid and like a lightning bolt. That is the solar affect.” ...

A “space weather” conference in Washington DC last week, attended by Nasa scientists, policy-makers, researchers and government officials, was told of similar warnings.

While scientists have previously told of the dangers of the storm, Dr Fisher’s comments are the most comprehensive warnings from Nasa to date.

Dr Fisher, 69, said the storm, which will cause the Sun to reach temperatures of more than 10,000 F (5500C), occurred only a few times over a person’s life.

Every 22 years the Sun’s magnetic energy cycle peaks while the number of sun spots – or flares – hits a maximum level every 11 years.

Dr Fisher, a Nasa scientist for 20 years, said these two events would combine in 2013 to produce huge levels of radiation.

He said large swathes of the world could face being without power for several months, although he admitted that was unlikely....
