If you’re into science or engineering, you can explore space at planetariums galore. Chicago’s Adler Planetarium, the Western Hemisphere’s first, is on the list along with facilities in Michigan, New York, Texas and more.
Big-name museums are on the list. But smaller, more niche ones are a major feature of the event. And the list of participating institutions can give you ideas for future visits, too.
Visit Smithsonianmag.com/museumday to get a ticket. The website has a search function and a place to get your free tickets, which provide general admission for the holder and one guest.
Each email address can download only one ticket, so choose wisely — and get ready to immerse yourself in a museum you may not have even known existed.
