The Center for Astrophysics | Harvard & Smithsonian (CfA) hosts a variety of free programs for the public. Among these events are Observatory Nights, sponsored by the Harvard College Observatory, which feature a nontechnical lecture and telescopic observing from the observatory roof, if the weather permits. These lectures are intended for high-school age and older audiences but children are also welcome.  Admission is free; however, tickets are limited and seating is on a first-come basis.  These events are held in Phillips Auditorium, 60 Garden St., Cambridge, about one mile west of Harvard Square. Parking lots marked for Observatory staff are open to the public on event nights. Parking is free.
