Venus Transit

On June 5, 2012, the observatory hosted students, faculty, and interested persons in an observing session for the transit of Venus. Despite cloudy conditions, there were enough breaks to give people a chance to see Venus through the telescopes set up by the observatory.


The George Mason University Observatory at the Fairfax Campus building Research Hall, formerly known as Research I (see campus map here), officially opened 24 January 2007. There will be a number of informal night sky observing sessions scheduled this semester. Attendance at these sessions is open to all students, faculty, staff and the interested public.

The spring schedule for observing is posted HERE.

For information regarding visiting the observatory, directions, location, and guidelines, please see Observing.
