It’s almost time for the big 2024 solar eclipse. Here’s what you need to know.

If you didn’t get to experience the 2017 solar eclipse, Monday is your chance for a repeat. Between 12:51 p.m. and 3:22 p.m. in Chicago, you’ll be able to watch the moon cross between the sun and the Earth. You’d have to drive a few hours to witness a total eclipse, but the city will still offer a pretty spectacular view. Geza Gyuk, the Senior Director of Astronomy at the Adler Planetarium, told us Chicago will get 20 times darker than usual at the height of the eclipse at 2:07 p.m. In this episode, Gyuk talks to host Erin Allen about how to safely experience the wonder of this once-in-a-generation eclipse.
