Total Solar Eclipse & The Curious History of Invisible Light

On Monday, August 21st residents of just 10 states —and the millions of travelers making the trip for the chance to see a rare phenomenon—will be able to witness the full totality of a solar eclipse.  The totality window spans a mere 70 miles wide.   Astronomer Bob Berman touches on the spectacular beauty of a total eclipse compared to a partial eclipse.

 Then we turn our attention to his latest book: “Zapped“.
Even during the darkest night sky, we’re surrounded by light. Science writer Bob Berman joins us to talk about the many kinds of light we cannot see – how they are crucial for life and how they can kill us if we’re not careful.
