Small World

The usual domestic election issues - like the economy and health care – may now be global issues. We look into how globalization is changing the nature of American politics. Also: our States of the Union election series looks at the issues in Illinois. The discovery of a dinosaur mummy. And on Underreported: details on the recent resurgence of the Taliban in Afghanistan. Guest host Julie Burstein sits in for Leonard today.

On tomorrow's Please Explain: find out how you can be an amateur astronomer!

To help us prepare, we want know which constellations you wish you could identify....and if you have a favorite stargazing spot here in the New York City area. Submit your comment here.
