Blue Marble

Nasa’s Blue Marble project involves twelve months of taking photos from a low orbit satellite and then stitching them together to produce some truly stunning images of the planet:

Blue Marble: Next Generation offers a year’s worth of monthly composites at a spatial resolution of 500 meters. These monthly images reveal seasonal changes to the land surface: the green-up and dying-back of vegetation in temperate regions such as North America and Europe; dry and wet seasons in the tropics, and advancing and retreating Northern Hemisphere snow cover.
