The sun has let loose its strongest flare yet today. Classified as a M6.5 flare, it was associated with an Earth-direction coronal mass ejection (CME), a solar phenomenon that can send billions of tons of solar particles into space and can reach our planet days later.
Solar flares are powerful bursts of radiation that can sling the harmful material through space toward Earth. Fortunately, this radiation cannot pass through our atmosphere to impact humans on the ground. However, it can sometimes disturb the atmosphere enough so that it disrupts radio signals.
