Events for the Public

The Harvard-Smithsonian Center for Astrophysics sponsors a variety of free programs for the public. Among these events are Observatory Nights held on the third Thursday of the month, six times per academic year. Observatory Nights feature a nontechnical lecture and telescopic observing from the observatory roof if weather permits. The lectures are intended for high-school age and older audiences but children are also welcome. We also sponsor a variety of other special observing events throughout the year. Admission is free and seating is first-come, first-served.

These events--unless otherwise noted--are held in Phillips Auditorium (at the rear of the CfA complex near Madison Street and large parking lot), 60 Garden Street, Cambridge, about 1 mile west of Harvard Square. Parking lots marked for Observatory Staff are open to the public on event nights. Parking is free.

The Observatory does not host private events.

Monthly Observatory Night
Thursday, May 16, 2019
7:30 pm: Footprints On Another World: Apollo Plus 50
Dr. Jonathan McDowell, Astrophysicist, Center for Astrophysics | Harvard & Smithsonian

Half a century later, Dr. Jonathan McDowell will look back at humanity's first voyages to another world. In December 1968, the crew of Apollo 8 became the first people to enter the gravitational sphere of the Moon, and seven months later, Armstrong and Aldrin headed for the surface in Apollo 11. Meanwhile, the Soviet Union's moon rocket exploded disastrously as its robot probes competed with NASA astronauts in the race to bring home the first moon rocks. Dr. McDowell will explain how the first landing stood at the tip of an immense effort as engineers from California to Cambridge, MA turned the impossible into history.
