Some of the highlights from this year’s IDA sessions include presentations spanning millennia of human interactions with the sky, including cultures from New Zealand to Guatemala and technologies from navigation to photography. Many of the talks are appropriate and exciting for both adults and children.

The IDA is a nonprofit organization dedicated to preserving and protecting the sky and the nighttime environment, especially by encouraging the use of outdoor lighting that does not scatter into the sky. This Space.com story from 2018 shows how you can reduce light pollution.
