While researchers celebrated the Chandra X-ray Observatory's 15 years of operation this past June, they were also puzzled by its latest finding: a mysterious X-ray signal radiating from the Perseus galaxy cluster. Could this be the signature of "sterile" neutrinos and partially explain dark matter? Now that's a good question!
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 (excluding June, July and August). 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. No reservations are necessary, but seating is limited to the auditorium's capacity. Admission is free.
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.
