Whole Earth. Composite satellite image of Earth centred on the Americas. This is Blue Marble 2000, one of the most detailed Earth images ever made. It was done to update the original blue marble images taken by Apollo astronauts. It is the result of the combination of data from three Earth-observing satellites. A GOES satellite took the overall Earth image, SeaWiFS gathered ocean colour data and the AVHRR instruments on POES satellites mapped the vegetation. Hurricane Linda, a huge spiral storm system, is at centre left. Relief features have been exaggerated by 50 times. The Moon (upper left) has been superimposed on the image, and is not to scale.
