A Decade of Sun

For the past 10 years now, NASA’s Solar Dynamics Observatory (SDO) has been capturing an image of the Sun every 0.75 seconds. To celebrate, NASA created this 61-minute time lapse video of all ten years, with each second representing one day in the Sun’s life. They have helpfully highlighted some noteworthy events in the video, including solar flares and planetary transits.

12:24, June 5, 2012 β€” The transit of Venus across the face of the Sun. Won’t happen again until 2117.

13:50, Aug. 31, 2012 β€” The most iconic eruption of this solar cycle bursts from the lower left of the Sun.

43:20, July 5, 2017 β€” A large sunspot group spends two weeks crossing the face of the Sun.
