Mission and Background

The ONU Observatory has a mission to educate and inspire the students of Ohio Northern University, as well as the surrounding community, about the rapidly evolving and exciting science of astronomy.  

The ONU Observatory has been in planning since about 2003, while its construction occurred between March and September, 2010.  The observatory is primarily used by ONU students in physics and astronomy classes, faculty,  and by the ONU Astronomy Club.   However, it is also opened up for public events on a semi-regular basis.

 The ONU Observatory (below) has a ramp and double doors facing west for handicap accessibility.  There is also a North entrance on the left side.View_From_WestONU Observatory - plan view from West

Above: An architectural sketch of the ONU Observatory showing how it is divided into four main parts:  the porch, the control room, the observatory room, and the restrooms.  Dashed lines indicate the maximum extension of the roll-off roof.   The image of Saturn was created with a darker colored, raised brick.

The ONU Observatory is located on the Northwest side of campus (see map).  Parking is located in the Wander Baseball Field lot just off of Lincoln Avenue.
