Cindy Luongo Cassidy of DarkSky Texas will be the speaker for the Georgetown Astronomy Club meeting.

Are we ignoring half of the conservation work that needs to be done? Cindy will explore the natural world and its processes that depend on the absence of artificial light. Living things need natural darkness for navigation, reproduction, circadian rhythms, photoperiodism, competition, predation, and general habitat protection. We humans need it too. Learn what we can do to extend our conservation work to the nighttime.

Join us in celebrating Liberty Hill’s International Dark Sky Community designation with our neighboring communities! Spend an autumn evening exploring the night sky and enjoying family-friendly fun.

Cindy’s talk will explore the natural world and the processes that depend on the absence of artificial light. It will include a number of species but will emphasize issues that plants have with artificial lighting. Issues of navigation, reproduction, circadian rhythms, photoperiodism, competition, predation, and general habitat protection will be covered. It will also touch on some issues that humans have with artificial light at night. The talk wraps up with a review of what each of us can do to protect living things during the nighttime.
