Super Earths are named for their size, but these planets - which range from about 2 to 10 Earth masses - could be superior to the Earth when it comes to sustaining life. They could also provide an answer to the ‘Fermi Paradox`: Why haven`t we been visited by aliens? http://www.physorg.com/news178821471.html Space & Earth Mon, 30 Nov 2009 16:38:28 EST news178821471 (PhysOrg.com) -- There are so many stars in our galaxy that even if planets with complex life (animals and plants) are rare - say one for every billion stars - there could still be dozens here in the Milky Way. But we are just beginning to learn about worlds beyond our solar system, called exoplanets, so we really don't have a good idea of what the chances are for advanced life. That's where NASA's Kepler mission comes in. http://www.physorg.com/news172242543.html Space & Earth Tue, 15 Sep 2009 14:30:01 EST news172242543 (PhysOrg.com) -- Using NASA`s Spitzer Space Telescope, an international team of astronomers have found that at least 1 in 100 white dwarf stars show evidence of orbiting asteroids and rocky planets, suggesting these objects once hosted Solar Systems similar to our own. http://www.physorg.com/news159460384.html Space & Earth Mon, 20 Apr 2009 15:33:37 EST news159460384 When NASA's Kepler telescope rocketed into the night sky last week, two Berkeley astronomers watching its fading contrail were hoping that the telescope will reveal Earth's - and humanity's - place in the universe. http://www.physorg.com/news156101002.html Space & Earth Thu, 12 Mar 2009 18:24:13 EST news156101002 (PhysOrg.com) -- Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars. Observations made with NASA's Spitzer Space Telescope reveal six dead "white dwarf" stars littered with the remains of shredded asteroids. This might sound pretty bleak, but it turns out the chewed-up asteroids are teaching astronomers about the building materials of planets around other stars. http://www.physorg.com/news150394045.html Space & Earth Mon, 05 Jan 2009 16:07:25 EST news150394045 (PhysOrg.com) -- Astronomers searching for rocky planets that could support life in other solar systems should look outside, as well as within, the so-called "habitable zone," University of Arizona planetary scientists say. http://www.physorg.com/news143131502.html Space & Earth Mon, 13 Oct 2008 15:45:02 EST news143131502
