Frontiers/Controversies in Astrophysics (ASTR 160) Class begins with a review of the first problem set. Newton’s Third Law is applied in explaining how exoplanets are found. An overview of the Solar System is given; each planet is presented individually and its special features are highlighted. Astronomy is discussed as an observational science, and the subject of how to categorize objects in the Solar System is addressed. The Pluto controversy is given special attention and both sides of the argument regarding its status are considered. Complete course materials are available at the Open Yale Courses website: open.yale.edu This course was recorded in Spring 2007.

Complete video at: fora.tv Bethany Cobb, a UC Berkeley postdoctoral fellow, discusses nasa’s Kepler Mission and its search for Earth-like planets in other solar systems. She predicts the mission will soon begin discovering “little rocky planets” orbiting distant stars. —– Learn about the great astronomy pioneer Edwin Hubble and how his use of a 100-inch telescope at the Mount Wilson Observatory in California not only resolved the “Great Debate” over the scale of the universe but also provided radical evidence that the universe is expanding. – Commonwealth Club of California Bethany Cobb is a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow at UC Berkeley. She received her Ph.D. at Yale University for research on massive stellar explosions called gamma-ray bursts. She is dedicated to sharing her love of astronomy with others and is the astronomer for The Old Farmer’s Almanac.

As the MESSENGER space probe approaches Mercury for its first flyby and close-up view of that planet, project principal investigator Sean C. Solomon, of the Carnegie Institution for Science, explains the significance of the mission. Topics include Mercury itself, the MESSENGER spacecraft design, the thermal challenges of a mission so close to the sun, the purpose and nature of the orbital flybys as MESSENGER matches orbits with Mercury, and the six big scientific questions that inform the mission.
