If the weather cooperates—that’s a big if—Chicago residents should see a partial eclipse between 12:51 p.m. and 3:22 p.m., reaching peak totality (around 94%) at 2:07 p.m. Naturally, the folks at the Adler Planetarium are ready to mark the occasion with a free indoor and outdoor (weather dependent) event with entertainment and education planned for the day.

For the cost of a museum ticket, astronomy enthusiasts can check out the moon crossing the sun in the telescope courtesy of the University of Chicago. There’s also a livestream with the Museum’s own NASA Solar System Ambassador, and plenty of activities for families and students.

Head to Navy Pier to watch the partial eclipse over the city skyline on Lake Michigan. Pullman National Historical Park is also hosting eclipse viewing with special guest star NASA ambassador Mark Benson and “eclipse-themed snacks.” Several of Chicago’s public libraries are having eclipse-themed events, including a plan to watch the partial eclipse from the garden of the Harold Washington Library Center and an interactive display at the Edgewater Library.
