Starry nights are only possible when we turn out the lights.  

The sky is a natural wonder that unites everyone in Illinois, our nation, and the world. The Milky Way, the orange glow of Jupiter, the constellations Orion, and the Big Dipper all capture our attention and fill us with awe. However, for many of us, the sky is not dark enough to see more than just a few stars. Explore how to take a closer look around your home and community to assess night light conditions and simple ways you can help keep our night skies dark.
