In honour of earth day, the Boston Globe has a great collection of photos well worth checking out: Earth Day 2010 Photos.
The most detailed true-color image of the entire Earth created 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 of our planet. Much of the information contained in this image came from a single remote-sensing device—NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS.
