Welcome to North Carolina’s Three College Observatory

We open this telescope for public and for group observing on certain nights each month.  Please see our “Public Nights” webpage. 

The Three College Observatory, located at a dark-sky location in central North Carolina, contains a 0.81-meter reflecting telescope, one of the largest in the southeastern United States.

The observatory opened in 1981 and is used for astronomical research, instruction of North Carolina college students, and sky observing by interested persons in the community.

The Observatory is operated jointly by The University of North Carolina at Greensboro, North Carolina A & T State University, and Guilford College. All three universities are located in Greensboro, North Carolina.


UPDATE, February 2024: UNCG has decided to eliminate the Department of Physics and Astronomy. We do not know what this means for the future of our faculty or facilities, including the TCO and our planetarium, though half of our faculty have already been invited to take a buy-out and leave.

If you value this programming, please express your concerns about its loss to the UNCG administration and consider signing/commenting on our petition.
