Astronomy Through the Ages

Astronomy Through the Ages (starts at 4:10): If I ask you to close your eyes and imagine an astronomer, what do you see? Maybe you think of a lone figure hunched all night over the eyepiece of a telescope in a big, domed observatory. Maybe you think of Jodie Foster, as Ellie Arroway in the movie Contact, wearing headphones to listen in on cosmic radio waves at Arecibo.

My mind always wanders back to a woodcut of Tycho Brahe’s 16th-century observatory, filled with intricate equipment for making naked-eye observations of the night sky.

But do any of these ingenious images actually resemble the life of an astronomer today? And how are new technologies and “big data” changing the way we study stars today and in years to come?

To discuss those questions, we’re joined in our Boulder studio by Dr. John Bally, a professor of astronomy at the University of Colorado, and Dr. Seth Hornstein, director of the Sommers-Bausch Observatory on the CU campus.

Colorado Drought // A More Perfect Heaven

A More Perfect Heaven: How Copernicus Revolutionized The Cosmos, by Dava Sobel

Colorado Drought Conference (start time 4:35): Experts are meeting at a conference in Denver this week to discuss the implications of prolonged drought conditions here in Colorado. How On Earth’ Susan Moran speaks with biologist Dr. Chad McNutt of the NOAA’s National Integrated Drought Information Center about wthe drought means for the ecosystem, and for Western cities — and how we can start to address the problem.

A More Perfect Heaven (start time 11:50): Joel Parker speaks with Dava Sobel, a science journalist and author who tells the stories of the science and the scientists from the past and how they connect to the present. Those stories reveal that the course of scientific progress is far from orderly — it often takes unplanned twists, has failures that require going back and starting over, and can be driven by the quirks of the personalities of individual scientists.

Today we hear about Sobel’s most recent book, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos.  This book also contains the play And The Sun Stood Still, which will be presented in a free staged reading by the Boulder Ensemble Theatre Company this Thursday, September 20th at 6:30 at the Dairy Center for the Arts.
