NASA's Kepler Discovery Confirms First Planet Orbiting Two Stars

September 15, 2011 (CERESTV.com) PASADENA, Calif. -- The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA's Kepler mission has made the first unambiguous detection of a circumbinary planet -- a planet orbiting two stars -- 200 light-years from Earth. Unlike Star Wars' Tatooine, the planet is cold, gaseous and not thought to harbor life, but its discovery demonstrates the diversity of planets in our galaxy. Previous research has hinted at the existence of circumbinary planets, but clear confirmation proved elusive. Kepler detected such a planet, known as Kepler-16b, by observing transits, where the brightness of a parent star dims from the planet crossing in front of it. "This discovery confirms a new class of planetary systems that could harbor life," Kepler Principal Investigator William Borucki, of NASA's Ames Research Center in Moffett Field, Calif., said. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now." A research team led by Laurance Doyle of the SETI Institute in Mountain View, Calif., used data from the Kepler space telescope, which measures dips in the brightness of more than 150,000 stars, to search for transiting planets. Kepler is the first NASA mission capable of finding Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist on the surface of the orbiting planet. Scientists detected the new planet in the Kepler-16 system, a pair of orbiting stars that eclipse each other from our vantage point on Earth. When the smaller star partially blocks the larger star, a primary eclipse occurs, and a secondary eclipse occurs when the smaller star is occulted, or completely blocked, by the larger star. Astronomers further observed that the brightness of the system dipped even when the stars were not eclipsing one another, hinting at a third body. The additional dimming in brightness events, called the tertiary and quaternary eclipses, reappeared at irregular intervals of time, indicating the stars were in different positions in their orbit each time the third body passed. This showed the third body was circling, not just one, but both stars, in a wide circumbinary orbit. The gravitational tug on the stars, measured by changes in their eclipse times, was a good indicator of the mass of the third body. Only a very slight gravitational pull was detected, one that only could be caused by a small mass. The findings are described in a new study published Friday, Sept. 16, in the journal Science. "Most of what we know about the sizes of stars comes from such eclipsing binary systems, and most of what we know about the size of planets comes from transits," said Doyle, who also is the lead author and a Kepler participating scientist. "Kepler-16 combines the best of both worlds, with stellar eclipses and planetary transits in one system." This discovery confirms that Kepler-16b is an inhospitable, cold world about the size of Saturn and thought to be made up of about half rock and half gas. The parent stars are smaller than our sun. One is 69 percent the mass of the sun and the other only 20 percent. Kepler-16b orbits around both stars every 229 days, similar to Venus' 225-day orbit, but lies outside the system's habitable zone, where liquid water could exist on the surface, because the stars are cooler than our sun. "Working in film, we often are tasked with creating something never before seen," said visual effects supervisor John Knoll of Industrial Light & Magic, a division of Lucasfilm Ltd., in San Francisco. "However, more often than not, scientific discoveries prove to be more spectacular than anything we dare imagine. There is no doubt these discoveries influence and inspire storytellers. Their very existence serves as cause to dream bigger and open our minds to new possibilities beyond what we think we 'know.'"

RIR W Thornhill The Electric Universe 12/12

Author and researcher Wallace Thorhill joins us to discuss his work and book "The Electric Universe". He has been working closely with David Talbot over at thunderbolts.info and he's one of the voices in the "Thunderbolts of the Gods" DVD. Previously we've had Donald Scott and Rens van der Sluijs with us on the program, also contributors to thunderbolts.info, now Wallace joins us for an excellent two hour program as we explore the exciting theory of the electric universe. Topics Discussed: Immanuel Velikovsky, The Saturn Myth, Ancient Solar system, Gravity, Electricity, Journal of Classical Physics, Einstein, the Electric Universe Theory, Quasars, Black Holes, The Standard Model of the Sun, Solar Activity, Anode, Glow Discharge, Photosphere, Magnetism, Twisted Pairs, DNA shape of a Galaxy, Dark Currents, Fractal, The Nature of Gravity, Infinite Speed, Nerve Signaling Speed, Tom Van Flandern, The Origins of the Universe, Longitudinal System, Tesla, Free Energy and more. Don't miss hour two coming up with Wallace Thornhill for Red Ice Members, a very interesting continuation as we talk about Deep Impact, Temple One, Comets, Gravity, Discharge, Lightning, Sprites, Earthquakes and the relationship between the Earth, the Sun, the Galaxy and the Universe. We also go into the very fascinating area of Proto-Saturn, Saturn as a Brown Dwarf, this is our origins, we talk about what Wall calls "the Purple Dawn of Creation" and where the mythology and stories comes from in terms of our ancient past with two suns. Our solar system used to be a Binary Star system. So what happened to Saturn, we can still see effects of that today with the rings of Saturn and the hexagonal glow at its poles? We talk about Venus, Mars, the Sun, The Moon and comet's. We also get Wall's take on the "Norway Spiral". We talk about Plasma Discharge, Time Travel and the search for E.T. as well.
