' 1 of 50 Newfound Alien Planets
More than 50 new alien planets  including one socalled superEarth that could potentially support life  have been discovered by an exoplanethunting telescope from the European Southern Observatory (ESO).
The newfound haul of alien planets includes 16 superEarths,[url=http://www.nikeairmaxbestsale.com/]cheap nike air max[/url], which are potentially rocky worlds that are more massive than our planet. One in particular  called HD 85512 b  has captured astronomers' attention because it orbits at the edge of its star's habitable zone, suggesting conditions could be ripe to support life.
The exoplanet findings came from observations from the High Accuracy Radial velocity Planet Searcher instrument, or HARPS. The HARPS spectrograph is part of ESO's 11.8foot (3.6meter) telescope at the La Silla Observatory in Chile.[Illustration and video of alien planet HD 85512 b]
"The harvest of discoveries from HARPS has exceeded all expectations and includes an exceptionally rich population of superEarths and Neptunetype planets hosted by stars very similar to our sun," HARPS team leader Michel Mayor of the University of Geneva in Switzerland said in a statement. "And even better  the new results show that the pace of discovery is accelerating."
The potentially habitable superEarth, officially called HD 85512 b, is estimated to be only 3.6 times more massive than Earth, and its parent star is located about 35 lightyears away, making it relatively nearby. HD 85512 b was found to orbit at the edge of its star's habitable zone, which is a narrow region in which the distance is just right that liquid water could exist given the right conditions.

"This is the lowestmass confirmed planet discovered by the radial velocity method that potentially lies in the habitable zone of its star,[url=http://www.nikeairmax1shopsale.com/]cheap air max 1[/url], and the second lowmass planet discovered by HARPS inside the habitable zone," said exoplanet habitability expert Lisa Kaltenegger, of the Max Planck Institute for Astronomy in Germany and Harvard Smithsonian Center for Astrophysics in Boston.
Further analysis of HD 85512 b and the other newfound exoplanets will be able to determine more about the potential existence of water on the surface.
"I think we're in for an incredibly exciting time," Kaltenegger told reporters in a briefing today (Sept. 12). "We're not just going out there to discover new continents  we're actually going out there to discover brand new worlds." [Infographic: Alien Planet HD 85512 b Holds Possibility of Life]
Astronomers used HARPS to observe 376 sunlike stars. By studying the properties of all the alien planets detected by HARPS so far,[url=http://www.nikeairmax1shopsale.com/]nike air max 1 uk[/url], researchers found that approximately 40 percent of stars similar to the sun is host to at least one planet that is less massive than the gas giant Saturn.
In other words,[url=http://www.nikeairmaxzonesale.com/]air max 90[/url], approximately 40 percent of sunlike stars have at least one lowmass planet orbiting around it. On the other hand, the majority of alien planets with a mass similar to Neptune appear to be in systems with multiple planets,[url=http://www.nikeairmaxbestsale.com/]air max 1 sale[/url], researchers said.
Astronomers have previously discovered 564 confirmed alien planets, with roughly 1,200 additional candidate worlds under investigation based on data from the Kepler space observatory, according to NASA's Jet Propulsion Laboratory in Pasadena,[url=http://www.nikeairmaxzonesale.com/]cheap nike air max[/url], Calif.

Austrian overcomes fear of heights to aim for slackline recordReuters  20 hours ago
FRANKFURT, May 25  An Austrian man tiptoed along a line strung 185 meters (607 feet) off the ground in Frankfurt on Saturday, attempting to set a new world record for "highlining" despite his fear of heights.
