Extrasolar planet Gliese 581c



On April 24, 2007 a significant discovery was made by the HARPS instrument of the European Southern observatory. The exoplanet of Gliese 581c is within the habitable zone where water -a necessary ingredient for life as we know it - could exist in liquid form. Gliese 581 c is the first extrasolar planet believed to possibly have a surface temperature similar to that of Earth although it is significantly bigger, possibly having a radius approximately 50% larger than that of Earth and approximately 2.24 times Earth's gravity. There is a lot of speculation on whether it really is habitable and if we have finally found the first alternative to a new earth.
