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 (0.4 square miles) of our planet. Much of the information contained in this image came from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite. Visualization date: August 2, 2002.
