From 1.8 Million Years Ago to Thousands of Light-Years Away

Oct 21, 2013

Today on River To River, host Ben Kieffer checks in with an astronomer here in Iowa, who has found something new while observing a solar system about 3,000 light years from Earth… A discovery that gives us insight on how alien solar systems are structured.

And, we look into the discovery of a 1.8-million-year-old human skull in Europe that has ignited debate on the origins of distinct species of ancient human relatives.

This program's guests include: Robert Franciscus, Professor in the Anthropology Department at the University of Iowa, and Steve Kawaler, Astrophysics Professor in the Astronomy Program of the Department of Physics and Astronomy at Iowa State University.
