Adler Planetarium



Spend an Evening Under the Stars

Don't miss your chance to spend a night at the museum!  Please note that Astro-Overnights are limited to children ages 6-12 with their families, scout group, or other special group. All children attending the evening-only portion or the full Overnight MUST be accompanied by an adult. 

  • Check out our hands-on activities
  • See two amazing sky shows
  • Telescope Observing (weather-permitting)
  • Enjoy a light snack
  • Savor a continental breakfast

Want to enjoy the evening, but can't spend the night? No worries. There is an evening-only option available. Enjoy the same program, but sleep in your own bed.
