NASA's Hubble Space Telescope has discovered 16 extrasolar planet candidates orbiting a variety of distant stars in the central region of our Milky Way galaxy. The planet bonanza was uncovered during a Hubble survey, called the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS). Hubble looked farther than has ever successfully been searched for extrasolar planets. Hubble peered at 180,000 stars in the crowded central bulge of our galaxy 26,000 light-years away. That is...

Finding planets that pass in front of their parent stars is so important to understanding how planets form that the European Space Agency will shortly launch the 35 million Euro COROT satellite to find them. But a team of UK, French and Swiss astronomers is already paving the way from the ground, with today's announcement of the discovery of two new Jupiter-sized planets around stars in the constellations of Andromeda and Delphinus. They are among the hottest planets yet discovered. Their...

Washington, DC- Using a network of small automated telescopes known as HAT, Smithsonian astronomers have discovered a planet unlike any other known world. This new planet, designated HAT-P-1, orbits one member of a pair of distant stars 450 light-years away in the constellation Lacerta. "We could be looking at an entirely new class of planets," said Gaspar Bakos, a Hubble fellow at the Harvard-Smithsonian Center for Astrophysics (CfA). Bakos designed and built the HAT network and is lead...

A team of European astronomers, led by T. Guillot (CNRS, Observatoire de la Côte d'Azur, France), will publish a new study of the physics of Pegasids (also known as hot Jupiters) in Astronomy & Astrophysics. They found that the amount of heavy elements in Pegasids is correlated to the metallicity of their parent stars. This is a first step in understanding the physical nature of the extrasolar planets. Up to now, astronomers have discovered 188 extrasolar planets,...

An international team of professional and amateur astronomers, using simple off-the-shelf equipment to trawl the skies for planets outside our solar system, has hauled in its first "catch." The astronomers discovered a Jupiter-sized planet orbiting a Sun-like star 600 light-years from Earth in the constellation Corona Borealis. The team, led by Peter McCullough of the Space Telescope Science Institute in Baltimore, Md., includes four amateur astronomers from North America and Europe. Using...

NASA -- A NASA-led team of astronomers have used NASA's Spitzer Space Telescope to detect a strong flow of heat radiation from a toasty planet orbiting a nearby star. The findings allowed the team to "take the temperature" of the planet. "This is the closest extrasolar planet to Earth that has ever been detected directly, and it presents the strongest heat emission ever seen from an exoplanet," said Drake Deming of NASA's Goddard Space Flight Center, Greenbelt, Md. Deming is the lead...

SANTIAGO, Chile -- A team of French and Swiss astronomers working at the La Silla observatory in Chile discovered a planet about the size of Neptune located some 20.5 light years from our solar system, the European Southern Observatory said on Wednesday. The still unnamed planet is located in the Libra constellation and has about 17 times the mass of the Earth. It takes only 5 days to complete its orbit around a star that has about a third the mass of the Earth's sun, the press release said....

NASA -- A NASA-funded astronomer has discovered a world where the sun sets over the horizon, followed by a second sun and then a third. The new planet, called HD 188753 Ab, is the first known to reside in a classic triple-star system. "The sky view from this planet would be spectacular, with an occasional triple sunset," said Dr. Maciej Konacki (MATCH-ee Konn-ATZ-kee) of the California Institute of Technology, Pasadena, Calif., who found the planet using the Keck I telescope atop Mauna Kea...

In the past decade, more than 130 extrasolar planets have been discovered. Almost all have been found using a technique that measures tiny changes in a star's radial velocity, the speed of its motion relative to Earth. Astronomer Alan Boss tells the story how the first of these discoveries came about. Astrobiology Magazine -- More than 130 extrasolar planets have been discovered to date. Most of these have been found using a technique that measures tiny changes in a star's radial velocity,...

Longueuil -- Soon after its launch two years ago by the Canadian Space Agency (CSA), Canada's "Humble Space Telescope" started making amazing observations-beyond the capacity of any other Earth- or space-based instrument. MOST, our suitcase-sized space telescope orbiting at 820 km, can fix its gaze upon a single star for up to eight weeks at a time. And with its unique combination of steady observation time and precision pointing, MOST can look for subtle variations in stars that are...
