Earth from Space, Blue Marble by NASA Tile

The Blue Marble This spectacular “blue marble” image is the most detailed true-colour 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-colour mosaic of every square kilometre (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. NASA
