The Earth screen saver displays an image of the Earth as currently illuminated by the Sun, from a variety of viewpoints. You can view the Earth from the Sun (day side), the night side, from the Moon, or from an arbitrary altitude above any point on the globe specified by latitude and longitude. Day and night regions of the globe are shown based on the current date and time. The image of the Earth shifts location on the screen every 10 minutes to avoid burning in the phosphor in one location.
The images are generated based on the cloudless Earth databases created by the NASA Goddard Space Flight Center from the MODIS instrument onboard the Terra satellite. The image of the Earth by night is based on nine months of observation by the Defense Meteorological Satellite Program. For further information and additional images, visit the NASA Earth Observatory site.
The Earth Screen Saver is available exclusively for 32-bit Windows systems such as Windows 95/98/Me and Windows NT/2000/XP.
