The first post of the new year is devoted to a beautiful film assembled from 17,520 images. The images were taken of Earth every half hour over the course of a year by a EUMETSAT meteorological satellite.
In the film, an entire solar year is compressed into 12 seconds. Roughly every three seconds therefore represents one terrestrial season, or, put another way, each second of the film corresponds to approximately one month.
The sequence begins on 19 September 2010, a few days before the autumn equinox. Exactly halfway through the film, at the six-second mark, the spring equinox can be seen across Earth as it appeared from space on the first day of Farvardin. The film ends upon reaching the autumn equinox of 2011.
