One of the top experts in the country on the eclipse will speak in Vincennes tomorrow. Fred Espanak is a retired NASA astrophysicist and will help those who attend the program understand the science of the event and what to expect.

Espanak, known as Mr. Eclipse, will be speaking tomorrow night at 6:30 p.m. at the Red Skelton Performing Arts Center on the VU Campus. The program is free. As a reminder, Daviess County will host another town hall forum at the Washington Community Building at Eastside Park starting at 6 p.m. for those who want to learn more about what is happening locally in our area.
