Blue Marble (Planet Earth)

From NASA on Flickr (full-size is here, and be sure to cruise around a bit while visiting there ... incredible stuff):

Also at The Big Picture:

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. Flying over 700 km above the Earth onboard the Terra satellite. (NASA/Goddard Space Flight Center)

Lots more unreal photography at The Big Picture.
