GLOBE at Night: An update and look ahead to IYA2009
2009
The ongoing loss of a dark night sky as a natural resource for much of the world’s population is a growing, serious issue that not only impacts astronomical research, but also human health, ecology, safety, security, economics and energy conservation. “Star hunts” or “star counts” provide “citizen-scientists” with a fun, fast and no-frills way to acquire heightened awareness about light pollution through firsthand observations of the night sky. Over the last two years, the GLOBE at Night programme has enabled citizen-scientists around the world to contribute measurements on sky-brightness to a growing global database in two ways: simple unaided-eye observations that anyone can do and quantitative digital measurements through a handheld, well-calibrated sky-brightness meter. As discussed in this article, the GLOBE at Night programme will serve as a basis for the IYA2009 global Cornerstone Project on Dark Skies Awareness, as well as the central programme for the US IYA2009 Dark Skies are a Universal Resource theme.
