Using a collection of satellite-based photographs, NASA scientists have stitched together a mosaic of every square kilometre of Earth.

These spectacular "blue marble" images are the most detailed true-colour image of the entire Earth to date.

NASA took months of observations of the land surface, oceans, sea ice, and clouds and transformed theminto a seamless, true-colour picture of our fragile planet.

Much of the information contained in these images came from a single remote-sensing device-NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS.

The images were taken flying over 700km above the Earth onboard the Terra satellite in 2002.
