STScI Joins The Search For Other Earths In Space Baltimore MD (SPX) Jun 26, 2009 
The Space Telescope Science Institute (STScI) in Baltimore, Md., is partnering on a historic search for Earth-size planets around other stars. STScI is the data archive center for NASA's Kepler mission, a spacecraft that is undertaking a survey for Earth-size planets in our region of the galaxy. The spacecraft sent its first raw science data to STScI on June 19. The Institute was the logic ... read moreFive 'Holy Grails' Of Distant Solar Systems 
Pasadena CA (SPX) Jun 15, 2009Angelle Tanner, a post-doctoral scholar at JPL and Caltech, studies planets in distant solar systems, called extrasolar planets. The golden prize in this field is to find a planet similar to Earth - the only planet we know that harbors life. While more than 350 extrasolar planets have been detected, most are gas planets, with no solid surface. Many are located in orbits closer to their ... more

Planet-Forming Disk Orbiting Twin Suns Revealed
Pasadena CA (SPX) Jun 12, 2009Astronomers have announced that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) radio telescope system clearly reveals the presence of a rotating, molecular disk orbiting the young binary star system V4046 Sagittarii. The SMA images of V4046 Sagittarii, which are being presented by UCLA graduate student David Rodriguez in a press conference at the American ... more Planet-Hunting Method Succeeds At Last 
Pasadena CA (SPX) May 29, 2009A long-proposed tool for hunting planets has netted its first catch - a Jupiter-like planet orbiting one of the smallest stars known. The technique, called astrometry, was first attempted 50 years ago to search for planets outside our solar system, called exoplanets. It involves measuring the precise motions of a star on the sky as an unseen planet tugs the star back and forth. But the ... more New Method For Finding Alien Oceans 
Greenbelt MD (SPX) May 27, 2009NASA-sponsored scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like alien (extrasolar) worlds have oceans. "A 'pale blue dot' is the best picture we will get of an Earth-like extrasolar world using even the most advanced telescopes planned for the next couple decades," said Nicolas B. Cowan, of the University of Washington. ... more Let The Planet Hunt Begin 
Moffett Field CA (SPX) May 14, 2009NASA's Kepler spacecraft has begun its search for other Earth-like worlds. The mission, which launched from Cape Canaveral, Fla., on March 6, will spend the next three-and-a-half years staring at more than 100,000 stars for telltale signs of planets. Kepler has the unique ability to find planets as small as Earth that orbit sun-like stars at distances where temperatures are right for possi ... more |

Mass Loss Leaves Close-In Exoplanets Exposed To The Core
Hatfield, UK (SPX) Apr 23, 2009An international team of scientists has found that giant exoplanets orbiting very close to their stars could lose a quarter of their mass during their lifetime. The team found that planets that orbit closer than 2% of an Astronomical Unit (AU), the distance between the Earth and the Sun, may lose their atmospheres completely, leaving just their core. The team, led by Dr Helmut Lammer of th ... more Lightest Exoplanet Yet Discovered 
Garching, Germany (SPX) Apr 23, 2009Well-known exoplanet researcher Michel Mayor has announced the discovery of the lightest exoplanet found so far. The planet, "e", in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist. These amazing disc ... more Kepler Captures First Views Of Planet-Hunting Territory 
Pasadena, CA (SPX) Apr 17, 2009NASA's Kepler mission has taken its first images of the star-rich sky where it will soon begin hunting for planets like Earth. The new "first light" images show the mission's target patch of sky, a vast starry field in the Cygnus-Lyra region of our Milky Way galaxy. One image shows millions of stars in Kepler's full field of view, while two others zoom in on portions of the larger region. ... more Hubble Finds Hidden Exoplanet In Archival Data 
Baltimore MD (SPX) Apr 03, 2009A powerful, newly refined image-processing technique may allow astronomers to discover extrasolar planets that are possibly lurking in over a decade's worth of Hubble Space Telescope archival data. David Lafreniere of the University of Toronto, Ontario, Canada, has successfully demonstrated this new strategy for planet hunting by identifying an exoplanet that went undetected in Hubble imag ... more |
