NASA squeezes three years of solar activity into a three minute time-lapse video: "Three years ago the very first images from the Solar Dynamics Observatory (SDO) were beamed back to earth. Since then, NASA’s SDO has effectively had continuous coverage of the Sun’s rise towards solar maximum, the period of the most intense solar activity in the 11 year solar cycle. NASA has now provided a fascinating snapshot of this ongoing research in the form of a time-lapse video that squeezes three years of solar activity into three minutes of footage."
