Use telescopes to observe planets, stars, and other wonders of the Universe with your own eyes. Knowledgeable staff will be present to answer questions and guide observing.
Stargazing will occur at the same time as the Starry Nights: An Evening of Planet-Hunting event, requires the purchase of tickets. You do not have to attend the Starry Nights event in order to use the telescopes.
This stargazing event will be held if weather conditions permit. For weather and closure updates, check @SIObservatory, call 202.633.2517 the day of the event, or ask at the Welcome Center when you arrive at the Museum.
Online visitors are invited to check the Observatory's Ustream channel for a live telescope view during our open hours, when available, as well as archived videos of the Sun, Moon, planets, and more.
Accessibility: The Observatory dome and terrace are accessible via ramp or steps. Written and touchable explanatory materials are available.
