Craig Posted January 11, 2012 Report Share Posted January 11, 2012 Our galaxy has at least 100 billion other worlds http://planetquest.j...asa.gov/news/38 Our Milky Way galaxy contains a minimum of 100 billion planets, according to a detailed statistical study based on the detection of three planets located outside our solar system, called exoplanets. The discovery, to be reported in the January 12 issue of Nature, was made by an international team of astronomers, including co-author Stephen Kane of NASA's Exoplanet Science Institute at the California Institute of Technology in Pasadena, Calif. The survey results show that our galaxy contains, on average, a minimum of one planet for every star. This means that it’s likely there are a minimum of 1,500 planets within just 50 light-years of Earth. The study is based on observations taken over six years by the PLANET (Probing Lensing Anomalies NETwork) collaboration, using a technique called microlensing to survey the galaxy for planets. In this technique, one star acts like a magnifying lens to brighten the light from a background star. If planets are orbiting the foreground star, the background star's light will further brighten, revealing the presence of a planet that is otherwise too faint to be seen.
