Planet Earth’s Northern Hemisphere

A timelapse of Planet Earth from Electro-L, a geostationary satellite orbiting 40000km above the Earth. The satellite creates a 121 megapixel image every 30 minutes with four visible and infrared light wavelengths. The infrared light appears green in these images, and shows vegetation.  The images are the largest whole disk images of our planet, the resolution is 1 kilometer per pixel.   The images are “masked” by a circular barrier that blocks out the light of the Sun and other stars.  This is to prevent damage to the camera by exposure to direct sunlight.  City lights are not visible because they are thousands of times less bright than the reflection of sunlight off the Earth.  The images have been interpolated (blended) to create a smooth animation.
