SETI Live - Volcanoes on Venus: A New Look at Old Data

As research teams around the world prepare for the launch of two separate missions to our 'sister planet' Venus, other scientists are spending their time looking through the data already collected by previous missions. Take, for example, the Magellan spacecraft, which mapped the surface of Venus from September 1990 through October 1994 using synthetic aperture radar. Last month, Science published a new paper detailing how scientists compared two radar images space eight months apart and discovered a volcanic vent that had grown and changed shape in that time period. 

Join co-author Robert Herrick from the University of Alaska Fairbanks and communications specialist Beth Johnson as they discuss how the discovery was made, how it changes what we know of Venus, and what the new information could mean for future Venus missions.
