Adler at Night

Escape the planet with exhibits about the first lunar missions, the solar system and more, plus immersive shows in the dome theater. The Doane Observatory is also home to the largest public telescope in the area, and gathers 7,000 times more light than the human eye. Every Wednesday, the Adler stays open late from 4pm-10pm so that folks can visit after work or school. And best of all, admission is free on those nights for Illinois residents.
