Magic of the Jack O’Lanterns

Children’s Museum of Denver: Color Outside the Lines

This will be the rare occasion that you book a babysitter and head to the Children’s Museum of Denver sans little ones. For the institution’s annual fundraiser—held in tandem with its 53rd birthday—adults can enjoy delicious bites (raclette, custom fried rice, steak frites), craft cocktails, music, and a silent auction. Sept. 18; 6–10:30 p.m.; $175

International Observe the Moon Night

It’s notoriously difficult to score tickets to Chamberlin Observatory’s weekly Astronomy Nights (they’re all sold out through November). But this special event will give locals a chance to look through the observatory’s iconic 26-foot-long Alvan Clark-Saegmuller refractor telescope—no ticket required. Peer through the lens and see if you can spot some of the moon’s many mountains or craters. The Denver Astronomical Society will also have additional telescopes set up on the south lawn for more celestial gazing opportunities, or, bring your own and the society’s members can show you how to use it. Sept. 19; 5 p.m.; free, RSVP here
