Description
Newly discovered extra-solar planet may be Earth-like
A planet 50% greater in radius and with about 5 times earth mass orbiting the red dwarf Gliese 581 has been discovered inside the constellation of Libra.
A 2005 search revealed that the star Gliese 581 possessed a Neptune sized planet, prompting astronomers to take a closer look. Gliese 581 c, as the planet is aptly named, has an estimated surface temperature between 0 and 40°C (32 and 104°F). Scientists claim the planet is likely to have an atmosphere and liquid water.
A second planet, about 8 times the mass of earth, was also discovered not too far from Gliese 581 c.
A team of scientists from France, Switzerland and Portugal discovered the planets using the ESO 3.6-m telescope from the High Accuracy Radial Velocity Planet Searcher or HARPS, located at the European Southern Observatory (ESO) in La Silla, Chile.
"The separation between the planet and its star is just right for having liquid water at its surface," said team spokesperson Stephane Udry of the Observatory of Geneva in Versoix, Switzerland. "That's why we are a bit excited."
"Liquid water is critical to life as we know it and because of its temperature and relative proximity, this planet will most probably be a very important [focus] of future space missions dedicated to the search for extra-terrestrial life.
On the treasure map of the Universe, one would be tempted to mark this planet with an X.

Exoplanete Gliese 581 La première exoplanète potentiellement similaire à la planète Terre vient d'être découverte. L'annonce a été faite ce jour par la revue scientifique Astronomy and Astrophysics qui publie un article réalisé par une équipe internationale franco-helvético-portugaise. Cette équipe a utilisé avec le spectrographe HARPS (High Accuracy Radial Velocity for Planetary Searcher) monté sur le télescope de 3,6 m de l'observatoire de La Silla au Chili. D'après l'équipe, ceci constitue « un grand pas dans la quête de la vie dans l'univers ». Cette planète, orbitant autour de la naine rouge Gliese 581 (Gl581, ou GJ 581) dans la constellation de la Balance et située à 20,5 années-lumière de notre planète, est la troisième exoplanète découverte dans ce système : les astronomes avaient observé auparavant une planète de masse comparable à celle de Neptune (environ 15 fois celle de la Terre) qui orbite autour de son soleil en 5,4 jours, et une autre de masse 8 fois celle de la Terre avec une période de révolution solaire de l'ordre de 84 jours. Les naines rouges constituent des « cibles » de choix pour les chasseurs d'exoplanètes en raison de leur luminosité relativement faible, ce qui favorise la détection des objets qui pourraient orbiter autour d'elles. Par ailleurs, ce type d'étoiles constitue environ 80 % des objets les plus proches du Soleil. L'intérêt suscité par Gl581c, la plus légère des quelques 200 et plus exoplanètes découvertes à ce jour, est dû à ses caractéristiques qui semblent en faire, selon l'expression de certains, une « Terre-bis ». Merci Magik
Fantastic image, Magik! wonderful write-up
Great work
Now if we can only come up with the money to build a star-ship to get there. ;D Fantastic work!
Very nice :) beau vert en passant.
Beautiful recreation my friend. This planet may be an example of what scientists speculate to be a "water giant". An in between body larger than Earth but smaller than Neptune which is now called an "ice giant".
super news! Not only one, but two were found - so cool... but, I think our governments are not telling us everything... maybe the computer will grow legs, take over man and say; "listen puny humans, your leaders have not been telling you everything... you have given us great knowledge and now it is our turn to tell you what is going on" LOL... hopefully the computer looks at us as mommy and daddy instead of this bug on earth that is killing the planet.... It's also cool the planet you made here is green, I bet they have Lepricans - lol
Magik, c'est une image fantastique mon ami. Gliese 581 semble être une magnifique planète et rempli de l'eau. Cela excite des nouvelles et j'ai apprécié l'histoire de cette planète beaucoup.
very cool!
FANTASTIC.
Lovely space scene. Cool planet and colors.
excellent image mu..
Love your space renders Magik and this one is gorgeous. Dana
That's a very interesting piece of work
ultimate cool my friend. love that planet.
Awesome work! Well Done!
lets go over there but lets try to keep the assholes off the planet,but then we might only be a few left over muahahaha.
Beautiful work!!
Très bon travail!!!
Thank you for this fantastic information, this are a very good news!!!! Have a great day, Ute PS. Thanks for the gift
Beautiful pic, very well done.
Tout est parfait !
Wonderful planetary system, my friend!!!
Superb !
Wow fantastic !!
Wonderful spacescape!!
Interesting info 'n' lovely image! (:
superb image!!
Very nice image. Space excites me and sets my imagination loose! Very cool image...
I know they are out there!I think you do too.Cant wait till we find some strange beings..it could be amazing all that we would learn..or it could be like a bad sci fi flick and we all would meet our doom..lol..Excellent space and info my friend...
