"This eruption is directed right at us, and is expected to get here early in the day on August 4th," says astronomer Leon Golub of the Harvard-Smithsonian Center for Astrophysics (CfA). "It's the first major Earth-directed eruption in quite some time."
Normally a blast of radiation like this could be expected to wipe out much of the human race, but fortunately we are protected by the Earth's magnetic field. Instead the deadly solar plasma is expected to stream down the planetary field lines towards the poles, crashing into oxygen and nitrogen atoms in the atmosphere and so lighting them up to form aurorae - the so-called Northern Lights.
