The Adler Planetarium hosts "Doane at Dusk," where guests can stay up late and observe the night sky at the Adler’s Doane Observatory, featuring the largest aperture telescope available to the public in the Chicagoland area. Guests can see a variety of celestial objects like the Moon, Jupiter, Saturn and more!

The start time for Doane at Dusk depends on the time of year. Please check the website. Start time is usually around 8pm, but during winter months, may start as early as 7pm. 

At Doane at Dusk, guests can enjoy nighttime telescope viewings and related discussions with Adler Astronomers after museum hours. This event is free and open to the public on a first come, first served basis. No tickets are needed.

Please note that Doane at Dusk is weather permitting. Guests can check Twitter @AdlerPlanet for updates. Should capacity issues require, the planetarium may close the guest line prior to the stated end time of the event so those ahead of that point can get into the Observatory by event’s end.
