Solar eruption sparks biggest radiation storm in 7 years

A powerful solar eruption is expected to blast a stream of charged particles past Earth on Tuesday, as the strongest radiation storm since 2005 rages on the sun.

NASA’s Solar Dynamics Observatory caught an extreme ultraviolet flash from a huge eruption on the sun overnight (10:59 p.m. ET Sunday, or 0359 GMT Monday), according to SpaceWeather.com.
