On Thursday, July 10 2025, the force will be strong with COSI After Dark: The Empire Strikes Bash!
Guests will find cosmic performances by Anna and the Annadroids, a chance to center yourself with Jedi-style meditation, and a make-your-own space buddy station (with model magic, of course). Come in costume, bring your fellows, and get ready to nerd out all night long. Light side, dark side, or somewhere in-between—the Force is strong with this night.
There are plenty of themed activities, plus you’ll enjoy the rest of COSI, ride the High Wire Unicycle, COSI Planetarium, and drinks at the cash bar from 7-10 pm. Buy tickets early!
Tickets for COSI After Dark tickets are $20 in advance, and $30 at the door (NOTE, some events have a higher ticket price due to additional activities). This event is for adults ages 21 and over, only. Valid photo ID required.
Add-on ticket to see Unofficial Galaxies. This incredible collection brings together iconic characters, stunning designs, and behind-the-scenes insights from one of the most beloved sci-fi franchises of all time. Tickets are an additional $15/person.

I’ve attended a few COSI after dark events and I must say that they’re an absolute blast to go to! Not only are you able to view all the exhibits with virtually no lines, but you have the added benefit of cash bars at almost every turn!
