Sun Struck

The space-weather forecast for the next few years: solar storms, with a chance of catastrophic blackouts on Earth. Are we prepared?

An X-class flare, the most powerful in NOAA’s classification system, overloads a sensor on the Solar  Dynamics Observatory. With the solar cycle expected to peak in 2013, more flares and coronal mass ejections (CMEs) may be headed earthward.  Photograph by NASA SDO, August 9, 2011 / National Geographic
