GREENBELT, Md., Jan. 6 /PRNewswire-USNewswire/ -- The most earthlike planet yet found around another star may be the rocky remains of a Saturn-sized gas giant, according to research presented today at the American Astronomical Society meeting in Washington. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) "The first planets detected outside our solar system 15 years ago turned out to be enormous gas-giants in very tight orbits around their stars. We call them 'hot...

Orbiting Telescope Designed to Find Earth-Like Planets NASA's Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system. Kepler's high sensitivity to both small and large planets enabled the discovery of the exoplanets, named Kepler 4b, 5b, 6b, 7b and 8b. The discoveries were announced Monday, Jan. 4, by the members of the Kepler science team during a news briefing at...

Two nearby stars have been found to harbor "super-Earths""• rocky planets larger than the Earth but smaller than ice giants such as Uranus and Neptune. Unlike previously discovered stars with super-Earths, both of the stars are similar to the Sun, suggesting to scientists that low-mass planets may be common around nearby stars. "Over the last 12 years or so nearly 400 planets have been found, and the vast majority of them have been very large"•Jupiter mass or even larger," says...

Crater patterns on Vesta and Ceres could help pinpoint when Jupiter began to form during the evolution of the early Solar System.  A study modeling the cratering history of the largest two objects in the asteroid belt, which are believed to be among the oldest in the Solar System, indicates that the type and distribution of craters would show marked changes at different stages of Jupiter's development.   Results will be presented by Dr Diego Turrini at the European Planetary...

In March, NASA launched its Kepler telescope with the hopes of discovering an Earth-like planet that could be hospitable to extraterrestrial life. However, one team of scientists has gone as far to say that the orbiting telescope will likely discover habitable "exomoons" as well. Writing in the Monthly Notices of the Royal Astronomical Society, Dr David Kipping and colleagues of University College London created a detailed method that scientists would need to follow while looking for...

An Australian website is giving users the opportunity to send their messages into space. People will be able to post messages no more than 160 characters to Gliese 581d, which is the nearest Earth-like planet outside the solar system that is likely to support life.  Users can do this from August 12 until August 24. The website said that the expected delivery time and day is about 20 years from now, and there is no guarantee of a response. "It's like a 'message in a bottle' cast out...

Astronomers using the Science and Technology Facilities Council's (STFC) William Herschel Telescope (WHT) on La Palma have confirmed an effective way to search the atmospheres of planets for signs of life, vastly improving our chances of finding alien life outside our solar system. The team from the Instituto de Astrofisica de Canarias (IAC) used the WHT and the Nordic Optical Telescope (NOT) to gather information about the chemical composition of the Earth's atmosphere from sunlight that has...

The U.S. space agency says a new planet-hunting technique has recorded its first discovery -- a Jupiter-like planet orbiting one of the smallest stars known. The National Aeronautics and Space Administration said the technique, called astrometry, involves measuring the motions of a star as an unseen planet tugs the star back and forth. However, the method had failed to identify any exoplanets. But now two astronomers from NASA's Jet Propulsion Laboratory using the technique have identified a...

U.S. space agency-sponsored scientists say they have developed a technique for determining whether Earth-like 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, Nicolas Cowan of the University of Washington said. "So how do we find out if it is capable of supporting life? If we can determine that the planet has oceans of liquid water, it greatly...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
