But there are ways for the individual astronomer to reduce its effect on our observing sessions. Many animals use natural lighting cues, such as positioning of the moon and stars as a component of their innate navigation systems allowing them to migrate, and excess lighting from cities or ill-placed light fixtures can confuse that system in those animals. And, unfortunately, many of us are exposed to unhealthy levels, aka blue light pollution. Light pollution is measured by a scale known as the Bortle Scale, which measures the sky's brightness. An additional major form of light pollution is sky radiance, the brilliant, shimmering effect of light from well-populated areas seen in the night sky. Measuring the Impacts of Light Pollution.
