Asteroid Hunters Mar 24, 2009

Show notes

Everyone knows that eight planets orbit the Sun. But thousands of other objects, including icy comets and football field-sized asteroids, are also zooming around our solar system.

Zeppelins Resurrected Mar 17, 2009

Show notes

The Hindenburg wasn't the only air ship to end in a catastrophic crash. In 1935, the USS Macon went down in 1000 feet of water off the coast of Monterey, California. Now, as scientists study the recently-discovered wreckage, dirigibles are returning to the Bay Area and are poised to rule the skies once again. But these aren’t the same dirigibles - these are new and improved.

Photographer Laura Watt has lived in the Bay Area for most of her life but it was not until she started sailing in San Francisco Bay at age 35 that she began to appreciate the patterns, textures and colors of the precious water that surrounds us all. Self-described as "trawler trash," she lives aboard her boat in San Rafael's Loch Lomand Marina, granting her a front row seat to the dynamic body of water that she captures so well in her moody, intimate images.
