Globe at Night - check the light polution in your neighbourhood !

Come Join the GLOBE at Night Program for a Star-Hunting Party during March 22 29, 2006!


What does it mean to REALLY watch the stars? When you look at the night sky, do you see an endless swath of glittering jewels set against a deep velvet black sky? Or do you see only a dozen or so pinpricks of light doggedly shining through the soft amber glow of streetlamps? And how could streetlamps make a difference
in the way the sky looks?

Join thousands of other students, families, and educators by participating in GLOBE at Night an international event designed to observe and record the visible stars as a means of measuring light pollution in a given location. Participation is open to anyone anywhere in the world who can get outside and look skyward during the week of March 22-29, 2006! There is no cost to participate in GLOBE at Night. Help us reach our goal of 5000 observations from around the world!

The quality of the night sky for stellar observations is impacted by several factors including human activities. By locating specific constellations in the sky, students from around the world will learn how the lights in their community contribute to light pollution. Students will explore the different light sources in their community learning the relationship between science, technology and society, and they will report their observations online through a central database allowing for authentic worldwide research and analysis. The observations made during GLOBE at Night will help students and scientists together assess how the quality of the night sky varies around the world.
