On Monday, a total solar eclipse will cross 14 states from Oregon to South Carolina. We find out people all across the country are preparing.

Also: we meet an eclipse chaser traveling to the US from Australia; we speak to a cloistered nun who has been getting calls from concerned Catholics worried about the end of times; we learn what solar eclipses have revealed to us about our universe throughout the ages; plus how a new technology can help blind people experience the coming eclipse as well.
