``Earth at Night" is a mosaic image of the nighttime earth using data from the weather satellites of the Defense Meteorological Satellite Program. Original data are chosen to be cloud-free and near new moon in order best to reveal city and highway lights, fires (manmade and natural), gas flares in oil fields, and fishing boats using lights. The resultant mosaic illustrates many of the resource and environmental issues that affect our planet, including of course light pollution.
This talk will be illustrated with the latest of these data, and relate my experiences in using these images for education, both within the classroom and for the general public.
