For ten years now, NASA’s Solar Dynamics Observatory has been capturing an image of Sol every 0.75 seconds from geosynchronous orbit around the earth. In this mesmeric hour long video, every second represents a day in the sun’s life, with various noteworthy events highlighted. To wit:

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

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

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