To mark Earth Month, NASA has given a shout-out to some of its satellites with a „greatest hits“ video. The two-minute compilation features the most spectacular images of Earth taken in 2012 — giving eye-popping views of glaciers, deserts, oceans, and even city lights from space.

Among the satellites featured are Aquarius, which measures sea surface salinity, and the Suomi National Polar-orbiting (NPP) satellite, which takes various climate measurements. There’s a stunning view of the planet at night (0:19), sand dunes formed by the wind over thousands of years in Egypt’s Great Sand Sea (0:32), and a massive 19-mile crack in the Antarctic ice sheet (0:49).
The video also includes data visualizations and computer models put together from the satellites‘ measurements, like the eerily beautiful animation of Hurricane Sandy’s 80-mph winds at 1:46. The highlight reel wraps up with a beautiful time-lapse of the „moonset“ as seen from the International Space Station.
