Astronomy and too much artificial light
Light pollution has a direct impact on the ability of astronomers to observe objects in the sky. Astronomers use telescopes as tools that collect light. A star creates its own light and that light travels across space. A telescope collects that light and allows the astronomer to learn more about the star. If there is too much artificial light around the telescope it blinds the telescope and affects the telescope's ability to collect the light from the distant star. Astronomers need dark skies to research the light from distant celestial objects.
Be an Astronomer and Protect Dark Skies
You can take star magnitude measurements in your community. We are collecting data on the amount of light pollution in the skies of Alberta. Follow our guide on how you can take your light measurements, submit them to our online form and we will develop a clear picture of where and how artificial light is affecting the skies in your community.
