The Henry Hudson Planetarium hosts a wide variety of educational and special event programs exploring astronomy, history, arts and science. And it's an official NASA Space Place! See list of upcoming events for shows like Stargazing: What's Up In The Sky Tonight?, Saturday Star Gazing and Follow the Drinking Gourd: Albany and the Underground Railroad. PLEASE NOTE: Based on the nature of our programming, once the star program has begun and the planetarium doors are closed, there is no admittance. Best policy is to arrive before the scheduled program time.
