Scientists Kickstart Global Light Pollution Mapping Project Based on ISS Photos

Scientists are tapping into photographs taken by astronauts aboard the International Space Station (ISS) to reliably measure the amount of light pollution worldwide. This study not only includes the well-known signatures of cities and streets, but also the effects of faint indirectly scattered light, which up to now had not been measured quantitatively. The new results confirm that this diffuse glow, which is seen from space, is scattered light from streetlights and buildings. This is the component responsible for the brightening of the night skies in and around cities, which drastically limits the visibility of faint stars and the Milky Way.

New Streetlight Design Curbs Light Pollution

For astronomers, a well-lit city means a sky unavailable for study. Worse, light pollution is blamed for affecting bird migration, sea turtle hatching, and wildlife mating and feeding routines. Researchers at National Central University, Taiwan, and Unidad Academica de Fisica, Universidad Autonoma de Zacatecas, Mexico, have attacked the problem with a new LED street lamp designed to shine only where needed, without splashing into unwanted areas, as a way to reduce light pollution while providing better lighting. Current street lights often use high-pressure sodium or merc...
