Life forms on the surface of Gliese 581 c - Flying fauna over Gliese 581 c - Artist's view of the exoplanet Gliese 581c housing an alien life form. Gliese 581c, with a radius of 1.5 times that of the Earth, is the first exoplanet gathering the necessary elements to imagine the existence of a possible extra-terrestrial life. From its surface, its star, about 100 times less bright than our Sun, must be large in the sky because of its proximity to the planet. Gliese 581 b, another planet in this system, passes past this star. Flying life forms grace the crimson skies of the potentially earth - like extrasolar planet Gliese 581 v. The red dwarf star Gliese 581 rests on the horizon, presiding over a liquid water sea. Eclipsing the red dwarf is Gliese 581 b, a sister planet in the same system with a mass 17 times that of the Earth. While the existence of all three bodies has been confirmed, it is not known if Gliese 581 c has all the necessary ingredients to support life as we know it
