This weekend, April 21st-22nd, Chicago-area volunteers are invited to join the Zooniverse team at Adler Planetarium for Earthfest, two days celebrating and contemplating the ways citizen science can positively affect our planet. You’ll be able to talk to team members, discover Zooniverse projects you may have missed, and take part in real-live demos of some of our favorite earth-related projects. The event is free with the price of Adler admission; learn more on the Adler Planetarium website. Hope to see you there!
