The last time a total solar eclipse spanned the continental United States from coast to coast was 99 years ago. Thousands joined in the Adler Planetarium’s celestial celebration to mark the occasion.

|

Onlookers were treated to a clear view of the solar eclipse in Carbondale. “It was a festival sort of atmosphere,” Amanda Vinicky said. “You literally had a beer tent, carnival rides, and band, a whole lot of very excited people wearing garb for the solar eclipse.”

Participating in the eclipse is a way for “people to demonstrate that they want to understand the world scientifically,” DePaul sociologist Roberta Garner says.
