Our Programs

Darkest Skies

Would you like to find the darkest skies in Missouri? Missouri still has over 50 parks and locations where the Milky Way is visible on a moonless night. We are building maps and tables so you can find the darkest skies in Missouri.

Sky Meter Program

How dark is our night sky? We have deployed Sky Quality Meters throughout Missouri to collect sky brightness data for scientific analysis and to help implement programs to reduce light pollution.

Citizen Science

Become a citizen scientist and have fun using your smartphone and telescopes! Explore projects that will help you measure and understand light pollution's impact on the night sky and and life on Earth.
