Biggest solar flare of the year showers the Earth

The largest solar flare of the year erupted from the sun earlier this month. Space weather is the stuff that gets spewed out by the sun and other stars -- electromagnetic energy, solar material. It travels through the solar system and interacts with everything it comes across, including the Earth's magnetic field. While we're mostly protected from harmful radiation, solar activity is sometimes disruptive and predicting it is difficult.
