    General Admission covers entry into campus, which includes guided tours, 150+ exhibits, historic buildings, Lowell Universe Theater shows and performances, and stargazing. Plus, add a rooftop Dark Sky Planetarium show or a Lowell Universe Theater show for $5 each.

    Can you return to the observatory if you leave after purchasing admission?
