Exoplanet House Of Horrors Washington DC (SPX) Nov 02, 2009
Astronomers may be closer than ever to discovering a planet that's habitable like our own, but along the way they've discovered some very scary exoplanets - places where conditions are far too harsh for life as we know it to exist. We've rounded up some of the most frightening, deadly exoplanets, places that make even the scariest haunted house on Earth pale in comparison. ... read moreCoRoT Mission Extended Until 2013
Paris, France (ESA) Oct 29, 2009Satellite operations for the CoRoT mission have been extended until 31 March 2013. The decision by the French Space Agency, CNES, and the mission partners, including ESA, was taken on 23 October at a specially convened meeting at the CNES Headquarters in Paris. Launched in December 2006, with a nominal lifetime of 3 years, CoRoT has steadily pursued its dual mission objectives of searching ... more

Nobel Prize-Winning Science - Springboard For Planet Hunting
Boulder CO (SPX) Oct 22, 2009The University of Colorado at Boulder and the National Institute of Standards and Technology have been awarded a $495,000 grant to look for Earth-like planets around other stars using technology based on 2005 Nobel Prize-winning research conducted at JILA, a joint institute of the two Boulder institutions. The funding from the National Science Foundation is to develop a precise "laser rule ... more 32 New Exoplanets Found
Paris, France (SPX) Oct 20, 2009At the international ESO/CAUP exoplanet conference in Porto, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO's 3.6-metre telescope, have reported on the incredible discovery of some 32 new exoplanets, cementing HARPS's position as the world's foremost exoplanet hunter. This result also increases the number of known ... more "Barcelona Process" Established To Guide Search For Habitable Exoplanets
Barcelona, Spain (SPX) Oct 14, 2009Exoplanet scientists from around the world gathered in Barcelona from September 14 to 18 to debate and reach a consensus on defining guidelines for a new roadmap with the ultimate objective of finding habitable, and potentially inhabited, planets outside of our Solar System. In addition they reached an agreement on an appropriate framework for developing such an initiative. ... more How Do We Know That Planets Exist Outside Our Solar System
Bonn, Germany (SPX) Oct 13, 2009Even in ancient times, people observed the planets that orbit our Sun. (See also the astronomy question from week 1: Why are there seven days in a week?) Nowadays we know that there are many trillions of other stars in the Universe, in addition to the Sun. It seems likely that planets orbit many of these stars too. The evidence that extrasolar planets (exoplanets for short) exist was ... more |

Mass And Density Of Smallest Exoplanet Finally Measured
Garching, Germany (SPX) Sep 17, 2009The longest set of HARPS measurements ever made has firmly established the nature of the smallest and fastest-orbiting exoplanet known, CoRoT-7b, revealing its mass as five times that of Earth's. Combined with CoRoT-7b's known radius, which is less than twice that of our terrestrial home, this tells us that the exoplanet's density is quite similar to the Earth's, suggesting a solid, rocky world. ... more Scientists wonder about planet's location
Newcastle-Under-Lyme, England (UPI) Aug 27, 2009 British scientists are trying to determine why a Jupiter-style planet orbiting close to its sun has not spiraled into the star and burned up. Wasp-18b is so close to the star Wasp-18 that it completes its orbit in less than an Earth-length day, astrophysicists at Keele University in Staffordshire say. In an article in Nature, they say standard astronomical theories hold the planet shoul ... more A Look Into The Hellish Cradles Of Suns And Solar Systems
Garching, Germany (ESO) Aug 20, 2009New images released by ESO delve into the heart of a cosmic cloud, called RCW 38, crowded with budding stars and planetary systems. There, young, titanic stars bombard fledgling suns and planets with powerful winds and blazing light, helped in their devastating task by short-lived, massive stars that explode as supernovae. In some cases, this energetic onslaught cooks away the matter that may ev ... more New Planet Orbits Backwards
Moffett Field CA (SPX) Aug 17, 2009A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK's WASP project in collaboration with Geneva Observatory. The discovery, which casts new light on how planetary systems form and evolve, was announced August 12 in a paper submitted to Astrophysical Journal. ... more |
