By searching for the same constellations in their respective hemispheres, participants in the Great World Wide Star Count will be able to compare their observations with what others see, giving them a sense of how star visibility varies from place to place. The observers will also learn more about the economic and geographic factors that control light pollution in their communities and around the world.Join in the count for fun and science.
If you want to know more about light pollution be sure to pick up a copy of the November issue of National Geographic. Their cover story, The End of Night - Why We Need Darkness will certainly open your eyes.
