Nasa mission to unravel sun’s threat to Earth
NASA is to embark on one of its most ambitious missions in an attempt to unlock the secrets of the sun.
Following its launch in nine days’ time, the US space agency’s Solar Dynamics Observatory (SDO) will spend five years in orbit trying to discover the causes of extreme solar activity, such as sun spots and solar winds and flares.
Scientists have long been aware that disturbances on the sun can trigger dangerous x-rays, charged particles and magnetic fields that can disrupt power supplies, communication signals and aircraft navigation systems on Earth.

The geomagnetic storm that results during this time could itself become apocalyptic...
