(Toronto National Post) It’s the job of NASA’s Solar Dynamics Observatory to keep an eye on the sun, a job the SDO has presented in a new video showing off three years’ worth of solar activity.

Will America’s neglected power grid and electronic infrastructure stand up to a major solar event? “A Nation Forsaken” will bring you out of your complacency.

“In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle,” NASA said in a release.
