Madison Astronomical Society (MAS) members are active in sharing the pleasures of astronomy with the public, acting as a resource for students and teachers, and exchanging information at Society meetings which occur monthly. The Society continues to pursue its original goal to “promote the science of astronomy and to educate the public in the wonders of the universe.”

MAS consists of people from many walks of life who are united by a genuine interest in astronomy. Our members are amateurs with skill levels ranging from novice to very experienced.

MAS is a non-profit organization promoting observational astronomy and discussions of astronomical topics.

Our aim is to bring the wonders of the universe to the public.

We maintain a dark-sky observatory where members can observe, image, and even do scientific research.

Our meetings are held the second Friday of each month except June, usually at UW Space Place, located at 2300 S. Park Street in Madison. Meetings often include discussions as well as speakers on a wide variety of astronomical topics.


MAS is a non-profit 501(c)(3) organization – donations are tax-deductible.
