This artistic illustration released by the European Southern Observatory on Tuesday, April 24, 2007, shows planets orbiting the red dwarf star, Gliese 581. Astronomers believe that the newly discovered planet Gliese 581 c, left, is potentially habitable.
An Earth-like planet spotted way beyond our solar system is the first found that could support liquid water a planet that is potentially habitable, Gliese 581. Also known as HO Librae c, Wolf 562 c, and HIP 74995.
It's the faint red object, not the bright white one that might be a historic find. The white object is surely a brown dwarf star.Credit: NaCo, VLT, ESO
Seth Shostak, a senior astronomer at the SETI institute, said the Gliese 581 system has been looked at twice in an astronomical survey for signs of intelligent life. The first time was in 1995 using the Parkes Radio Telescope in Australia, the second time occured in 1997 using the 140-foot telescope in Greenbank,West Virgina. Both observations revealed nothing.
