Planet HAT-P-1b orbits a star in a double star system. (Image credit: David A. Aguilar (CfA)) It's extremely large for its mass. In this picture, both stars are included - one is quite far away. Mona Evans, "Exotic Exoplanets Tour" http://www.bellaonline.com/articles/art32334.asp
July 1, 1996: Worlds of a Distant Sun: 47 Ursae Majoris b - Credit and Copyright: John Whatmough, Extrasolar Visions - Explanation: Within the last few years, observational astronomy has given humanity evidence of the existence of worlds beyond the solar system. Indeed, solar-type stars are now inferred to harbor planets of approximately Jupiter mass - some residing in temperature zones which could conceivably support liquid water and therefore life! More...
handout photo from the European Space Agency released December 10, 2008 shows an artist's impression of the Jupiter-size extrasolar planet, HD 189733b, being eclipsed by its parent star. Astronomers using the Hubble Space Telescope have measured carbon dioxide and carbon monoxide in the planet's atmosphere. The planet is a ?hot Jupiter?, so close to its parent star that it completes an orbit in only 2.2 days.
Nasa’s Astronomy Picture Of The Day – Extrasolar Super-Earth Gliese 1214b Might Hold Water
Years ago, when the first transiting exoplanet (HD 209458b) was found, I was startled to realize that it could be easily detected using a small, inexpensive telescope. Transiting exoplanets are planets that orbit other stars, and from Earth we just so happen to see their orbit edge-on. That means it...
Astronomers detect water in atmosphere of nearbyexoplanet - Life as we know it requires water, so a great deal of effort has been expended searching extrasolar planets for evidence of this vital molecule. Astronomers have now reported that
Distant exoplanet: Booted Out Into Interstellar Space ACCORDING TO A NEW STUDY, THE MASSIVE LONELY EXTRASOLAR PLANET KNOWN AS HD 106906B MAY HAVE BEEN FLUNG-OUT OF ITS SOLAR SYSTEM BY ANOTHER NEIGHBORING PLANET.
