Learn the importance of a dark sky for nature.

For every light-filled day, there should be a dark-filled night. Increasingly, artificial light fills the night sky. This light pollution disrupts the lives of plants, mammals (including humans), reptiles, amphibians, birds and insects. 

Join us as speaker, Ken Walczak, describes changes in the night sky over time and how those changes impacts the living world. Discover the beauty of nocturnal earth and learn how you can help protect the darkness and the creatures that depend upon it. Ken will offer simple actions that all of us can implement.

Far Horizons is a scientific research and engineering program that engages students, volunteers and the public in hands-on research projects. Ken has co-authored numerous scientific papers on light pollution research.
