This Is the Definitive Photograph of Planet Earth

10 May

This Is the Definitive Photograph of Planet Earth.

From Gizmodo:

This is the highest resolution image of Earth ever made, 121 megapixels. That’s an amazing 0.62 miles per pixel. It was taken by Russia’s latest weather satellite, the Electro-L, which is orbiting Earth on a geostationary orbit 36,000 kilometers above the equator, sending photographs of the entire planet every 30 minutes.

The image combines four light wavelengths, three visible and one infrared. The three reflected sunlight bands can simulate a conventional red-green-blue color picture. The near infrared channel (orange in the image) is a vegetation indicator, since plants reflect near-ir as well as green.
