Geeked on Goddard » The birth, life, and death of alien planets: Goddard exoplanet scientists give you an update on what we (think) we knowThe official count of candidate planets around other stars recently hit a whopping 500. But when the first extrasolar planets — often called exoplanets — were discovered, many scientists weren’t sure if they should believe their own data. The first confirmed exoplanets were found around a stellar corpse called a pulsar, born of a supernova explosion of a star. And we also found lots of so-called hot Jupiters, huge steaming gasballs orbiting many times closer to their host stars than Mercury orbits the sun.
MADRID (Reuters) - Eric Abidal was included in Barcelona's squad to play Celta Vigo in La Liga this weekend only a few days after coach Tito Vilanova returned following two months out receiving cancer treatment. France international Abidal, 33, has not played since having a liver transplant last April, and was passed fit to return to training with his team mates last month. His return is timely with fellow defenders Carles Puyol, Adriano Correia and Jordi Alba all out injured for Saturday's trip, and a Champions League quarter-final first leg away to Paris St Germain approaching next Tuesday. ... <p style="text-align:right;color:#A8A8A8"></p>

HLA Data Release 5 The Hubble Legacy Archive (HLA) announces the availability of Data Release 5 as of March 8, 2011. New in this release are a new, interactive footprint interface (pictured); multi-wavelength source lists; high-level WFC3 science products from the Early-Release Science and the Multi-Cycle Treasury program CANDELS; and the ability to obtain source information directly from the Interactive Display overlay.
"If we picture these jets as giant hoses and the water droplets as bullets, the amount shooting out equals a hundred million times the water flowing through the Amazon River every second," said Lars Kristensen , a postdoctoral astronomer at Leiden University in the Netherlands. "We are talking about velocities reaching 200,000 kilometers [124,000 miles] per hour, which is about 80 times faster than bullets flying out of a machine gun," said Kristensen, lead author of the new study detailing the discovery, which has been accepted for publication in the journal (Related: "Dimmest Stars in Universe Spotted?" ) Located in the northern constellation Perseus, the protostar is no more than a hundred thousand years old and remains swaddled in a large cloud—gas and dust from which the star was born.
Our poor universe shows bruises from collisions with other universes Just when the search for exoplanets looked like the undisputed fashionable field of study for 2010, the cosmic microwave background (CMB) is stepping to the forefront of astronomy and cosmology. Last month, it was Oxford’s Roger Penrose claiming that he’d found evidence of a cyclical universe in patterns of concentric circles in the CMB, suggesting our universe is just one of many that have come before it (and will come after it).
Earth could be getting a second sun , at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au .
The object is the first rocky planet discovered by NASA's Kepler spacecraft The discovery has scientists optimistic about what else could be found Kepler is capable of finding Earth-size planets in a habitable zone, NASA says (CNN) -- A NASA spacecraft has detected a rocky planet that is the smallest ever discovered outside the Sun's solar system, the agency announced Monday. The exoplanet -- so named because it orbits a star other than the Sun -- has been dubbed Kepler-10b. It measures 1.4 times the Earth's diameter and was confirmed after more than eight months of data collection, the agency said. It is the first rocky, or Earth-like, planet discovered by Kepler. "All of Kepler's best capabilities have converged to yield the first solid evidence of a rocky planet orbiting a star other than our sun," said Natalie Batalha, deputy science team leader for the NASA mission.
VATICAN CITY -- E.T. phone Rome. Four hundred years after it locked up Galileo for challenging the view that the Earth was the center of the universe, the Vatican has called in experts to study the possibility of extraterrestrial alien life and its implication for the Catholic Church. "The questions of life's origins and of whether life exists elsewhere in the universe are very suitable and deserve serious consideration," said the Rev. Jose Gabriel Funes, an astronomer and director of the Vatican Observatory. Funes, a Jesuit priest, presented the results Tuesday of a five-day conference that gathered astronomers, physicists, biologists and other experts to discuss the budding field of astrobiology – the study of the origin of life and its existence elsewhere in the cosmos.

Other Web Cam Options for Viewing the Lunar Eclipse Cloudy skies over much of the U.S. might make for challenging viewing tonight for the solstice lunar eclipse. To help work around the mercurial weather, here’s a list of web sites that are offering live web views. Many of these are located in parts of the country where the weather is clear – and you can still check out the Marshall Space Flight Center Web cam . We’ve had some breaks in the clouds, and we’re hoping for the best as the eclipse time draws closer. Check back on this page throughout the evening for added links.
