Keeping our skies dark

The Peterborough Astronomical Association is dedicated to preserving the night sky and is actively involved in lobbying municipalities and corporations to take steps to reduce "light-pollution".

Light pollution is the effect that large-scale lighting - such as in most cities - has on our view of the stars at night.
