EARTH AS ART

The US Geological Survey has put together several collections called Earth As Art. They feature Landsat satellite images selected for their artistic quality, rather than for scientific reasons. The Landsat programme is a series of Earth-observing satellite missions jointly managed by NASA and the US Geological Survey. Since 1972, Landsat satellites have collected information about Earth from space. The images are presented in "false colour" - satellites use both visible and invisible parts of the electromagnetic spectrum. Near-infrared light is invisible to the human eye, but adding it to these images allows scientists to "see" the surface of the Earth in other than natural colours.
