Observatory Status
Friday, July 11
Weather permitting, we will be open in the evening of Friday, July 11. Check that day for updates!
Observatory Open Houses are generally held on Friday evenings, weather permitting, starting typically an hour after sunset. Opening and closing times vary with the seasons, weather and other factors. Checking this webpage after 4 p.m. the day of a tentative event is the best way to be informed. Open Houses are free and open to the public.
Summer 2025 Update: We plan to be open most Fridays throughout the summer except July 4, August 8, August 15, and when the weather is uncooperative. Final decisions will be announced on this website as early as possible on the day of the event. We look forward to the return of Saturn in early Fall and Jupiter over the winter. Until then, we will often make use of our cameras and do imaging of deep sky objects such as star clusters, nebulae and nearby galaxies. Some of the images so acquired are available here.
Click here for directions for Observatory Open Houses. When trying to enter the Bloomberg Center for Physics and Astronomy in the evening, some doors will be locked. The door on the northeast side (facing the athletic practice field) is often open. If not, walk clockwise around the building to the courtyard on the campus side, and if necessary wait there until someone can let you in. Once you’re in the building, you can take the main elevator to the 4th floor and use the stairs next to it to climb the rest of the way to the roof.
The Morris W. Offit Telescope is the major observing instrument located under the Stanley D. and Joan F. Greenblatt Dome, on the roof of the Bloomberg Center.
