Welcome
The Leitner Family Observatory & Planetarium is a facility of the Yale Department of Astronomy dedicated to education, public outreach, and student research.
We will resume our weekly Tuesday Night Planetarium shows on August 26, 2025. There is no fee required for planetarium shows, but we welcome you to pay an optional admission fee. We are not able to reserve seats, so please arrive early if you are bringing a family or group.
Outdoor telescope observing will take place after sunset on Tuesday evenings, weather permitting. Be sure to check the announcement banner at the top of the website for the most up-to-date information or cancellations, as well as our calendar for planning purposes.
Reservations are not required for planetarium shows or outdoor observing.
