Earth Day Timelapse

by Nancy Atkinson on April 22, 2012

In honor of Earth Day, enjoy this beautiful timelapse compiled by science educator James Drake, who put together one of the first ISS flyover videos. This video was created from images produced by the Russian geostationary Electro-L Weather Satellite, and the images are some of the largest whole disk images of our planet, as the satellite is orbiting at about 40,000 km. Each image is 121 megapixels, and the resolution is 1 kilometer per pixel. They are taken every half hour in four different wavelengths of light — three visible, and one infrared. The infrared light is reflected by forests and vegetation, which appear orange in these images. Enjoy!

See more at Drake’s Planet Earth web page, including a zoomable, full resolution image of Earth, as well as other image downloads.
