Mars Puts On A Show Right After Sunset

Each month, on the first Sunday of the month, College of DuPage Astronomy professor Joe DalSanto joins First Light host Brian O'Keefe for a discussion of what you can see in the night sky in the coming weeks. For August, Mars will continue to be a prominent feature just after sunset, and that renews interest in our closest neighbor in the solar system.
