Newfound Alien Planet a Top Contender to Host Life
A newly discovered alien planet may be one of the top contenders to support life beyond Earth, researchers say.The newfound world, a "super Earth" called Gliese 163c, lies at the edge of its star's habitable zone — that just-right range of distances where liquid water could exist."There are a wide range of structures and compositions that allow Gliese 163c to be a habitable planet," Xavier Bonfils, of France's Joseph Fourier University-Grenoble, told SPACE.com by email.He went on to caution that several possible uninhabitable combinations exist as well.

A newfound super Earth
Bonfils and an international team of astronomers studied nearly 400 red dwarf stars with the High Accuracy Radial Velocity Planet Searcher (HARPS), a spectograph on the 3.6-meter telescope at the European Southern Observatory's La Silla Observatory in Chile.Gliese 163c was one of two alien planets found orbiting the star Gliese 163, which lies about 50 light-years from Earth in the Dorado constellation. The team found indications of a third planet as well but cannot confirm it at this time.Weighing in at about seven times the mass of Earth, Gliese 163c could be a rocky planet, or it could be a dwarfed gas giant, researchers said."We do not know for sure that it is a terrestrial planet," Bonfils said. "Planets of that mass regime can be terrestrial, ocean, or Neptune-like planets."Orbiting at the inner edge of the habitable zone, Gliese 163c takes 26 days to zip around its parent star, which is considerablydimmer than our sun.
This is really old news, i read about this along time ago, i think they have found alot of super earths, which if they are super earths its reasonable to assume life has evolved on those planets too, but still, nonetheless, its always interesting to come across this stuff.
If there are species on there, i dont believe they would be primarily hostile, like stephen hawkings said, if aliens exist they are most likely friendly, but it all depends, because a society that has expanded into the stars should know the frailty of life and not have a mission to vanquish it, im sure there are other mainly hostile species, but for the majority of it, you would have to be a pretty stupid species to be completely hostile.
Kind of like us today...
But not everyones stupid, just mean, which is stupid, a=b but b=/=a
