I saw this article last night on International Dark Sky Week 2020 starts Sunday — here’s how to celebrate online: https://www.space.com/international-dark-sky-week-2020-celebrate-online-guide.html.
Celebrate International Dark Sky Week from anywhere, with sessions streaming online starting Sunday (April 19).
The International Dark-Sky Association (IDA)’s annual event will be held between April 19 and 26. The full schedule is available here.
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.
