International Dark-Sky Association Research

Light at night and the various forms of light pollution have measurable effects on humans, nighttime ecosystems and more. There is a growing body of scientific research that is attempting to measure and understand these effects. The IDA, along with the Loss of the Night Network, maintain a comprehensive, searchable database of scientific publications on artificial light at night. The only database of its kind, the Artificial Light at Night (ALAN) Research Literature Database provides references to scientific literature on all aspects of artificial light at night research.

To access this ALAN Database click here. Please note that no login is required. The search window is in the upper right. Research on specific topics can be found by entering a key word (such as sleep, birds, cancer, etc.) into the window and then clicking on the Search button.

Protect your community from Light Pollution!

The Comal County Friends of the Night Sky was formed in April, 2020 by a group of concerned residents who first met using Zoom. We are working on several initiatives to facilitate night sky friendly lighting in order to preserve and improve the stunning night sky of the Texas Hill Country and Comal County, TX.
