Every year, our planet experiences two equinoxes: the fall equinox and spring equinox. If you live in Chicago—or any city built using a grid system—you will experience a golden phenomenon in the days on and right after each equinox. So, what is an equinox? And why does Chicagohenge occur? Turn the celestial calendar from summer to fall with Nick in this week’s edition of Skywatch Wednesday.

Skywatch Wednesday is a production of the Adler Planetarium—the first planetarium in the Western Hemisphere! Located on Chicago’s lakeshore, the museum typically hosts more than half a million visitors each year and reaches millions more through youth STEAM programs, neighborhood skywatching events, people-powered research, and other outreach efforts. Today, the Adler is bringing our unique approach—scientific exploration rooted in community and connection—to guests from around the world who can enjoy the digital Adler from their own homes, libraries, schools or offices.
