Astronomers at NASA's Solar Dynamics Observatory have recently captured images of the first significant X-class solar flare (powerful bursts of radiation) of the year on March 11, 2015.
Harmful radiation from a solar flare cannot pass through Earth's atmosphere to physically affect humans on the ground. However, when intense enough, it can disturb the atmosphere in the layer where GPS and communications signals travel.
