Two powerful 'X-class' flares erupt on sun

The sun unleashed two extremely powerful flares Tuesday. NASA tentatively says that particles from the solar storms are probably heading in Earth's direction, but will likely deliver a glancing blow at most.

This image from NASA's Solar Dynamics Observatory shows the sun as it unleashed an X5.4-class solar flare at 7:04 p.m. EST on Tuesday. The flare appears as the bright spot in the upper left.
