October 2012 Full shows @ http://www.youtube.com/user/MayanWarriors 200 classic shows Volumes 1 & 2 www.youtube.com/playlist?list=PLdA-7-ZlhQ7v3x5wXuWujvV8Vnkshh7cj www.youtube.com/playlist?list=PLdA-7-ZlhQ7st8aHye812dtzwrcfV7o3n http://jetstreamnews.com/ Date: 03-28-12 Host: George Noory Guests: Dimitar Sasselov In the first half of the show, Professor of Astronomy at Harvard University, Dimitar Sasselov, discussed the unprecedented breakthroughs in exoplanetary astronomy, and how they will shed new light on our place in the universe. He coined the term "super-Earth," which refers to rocky planets like Earth, only much larger. A number of such exoplanets have been discovered in the last few years, and recently there's been speculation that there could be billions of such super-Earths in our galaxy alone. While the Kepler Mission has excelled at discovering planets, they tend to be too far from Earth to adequately study their atmospheres and surfaces, he noted. So the next big step will be to discover planets that are closer to us and to look for signatures of life, he continued, adding that there's a proposal for a survey satellite called TESS which could locate planetary targets amongst the nearest stars for detailed viewing by the James Webb telescope (the successor to Hubble). Sasselov also talked about the transit of Venus on June 5th, the only time this planet will be seen moving between the Earth and the Sun this century.
