On today's show as we join Worldview host Jerome McDonnell broadcasting from the WBEZ terrace: Astronomy historian, Steve Ruskin, will share how the 1878 eclipse changed science and technology forever.We hear great eclipse stories from listeners like Celine Woznica. She was in Oaxaca, Mexico for the 1991 eclipse. Celine is eclipse-watching today in Missouri while pumping out tunes from her “eclipse playlist”. Plus: Live updates from special guests smack-dab in the "path of totality", like WBEZ’s Marc Garber. He’s camping out in Wyoming and comedian and science nerd, Aaron Freeman, who’s in Bloomsdale, Missouri.
