Abstract

Data obtained by US DMSP satellites were analyzed to obtain light energyin order to monitor light pollution at different countries. Light detectedby the satellites is one ejected to space and is not mostly used toilluminate objects to be seen. This light is energy loss and produce lightpollution for astronomical observation. We should reduce such energy lossand light pollution.
