This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet.
These are from the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on the Terra satellite, flying in a 700-km orbit. I think some of the other Blue Marble imagery came from the Aqua satellite. Neat stuff.
