About MAS


Please see “Featured Events” for details.

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.

Special Opportunity!

Course on the History of Astronomy and Cosmology

Interested in the history of astronomy?  Dr. Jim Lattis, Director of UW Space Place, will be offering a UW-Madison course on the subject this summer.  Astronomy/History of Science 206, History of Astronomy and Cosmology, will be offered in the first summer term, 17 May through 10 June.  The class will be taught in a hybrid format, with most of the lectures online through the UW Canvas course system, but with occasional (roughly twice per week) in-class meetings on campus.  These class meetings will nominally be from 9:50am until 12:20 pm (but probably shortened in practice).

Included this summer will be an exclusive field trip and tour of historic Yerkes Observatory, in Williams Bay, Wisconsin, arranged especially for students enrolled in this class.  The course confers three credits for regularly enrolled students.  (It might still be possible to enroll as a senior guest auditor via this link)

For more information or questions about the course, email lattis@astro.wisc.edu.
