NASA shows 3 years of Sun images in 3 minutes

Video showcases highlights of its solar satellite

NASA today posted this video combining three years of images provided by its Solar Dynamics Observatory (SDO).


According to NASA, the SDO's "Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths." At the wavelength of these images (171 Angstroms), you can easily see the sun's 25-day rotation, as well as the increase in solar activity.

More solar goodies can be found at this NASA site, including a full HD version of all four different wavelengths (in case you don't like yellow).
