Adler After Dark at Adler Planetarium featuring Cosmic Caper is April 18 from 6:30pm to 10:30pm. 21+. Tickets

You’ve just received a cryptic letter from an old associate—they want you to attend a gala at the museum and recover an artifact of great value hidden in the exhibits. Can you follow a series of elaborate clues, solve cryptic puzzles, uncover the mole, and find the item before more sinister people do? Time is running out, and only YOU and your crew can solve this caper of cosmic proportions.

In between your sleuthing, don’t forget to:

  • Try a special beer brewed just for the event in collaboration with our friends at Empirical Brewery
  • Check out a special talk by Adler astronomer Mark Hammergren and curator Pedro Raposo on some of astronomy’s greatest mysteries and the history of searching for “hidden things” in the cosmos
  • Enjoy special performances by Lakeside Pride Music Ensembles, a musical organization committed to the education of the LGBTQ community through public musical performances
