CNers have asked about a donation box for Cloudy Nights over the years, so here you go. Donation is not required by any means, so please enjoy your stay.

Science! Astronomy & Space Exploration, and Others

Discuss all science topics, particularly the sciences relating to Astronomy and Space Exploration. This includes all the natural sciences: Physics, Chemistry, Geology, and Biology. They can include applied sciences such as engineering and construction as well. Wherever the scientific method is used, you can discuss it here. As always, no politics, pseudo-science, crack-pottery, or anti-science.
