Until now, astronomers have confirmed more than 700 of the thousands of planets outside our solar system.

A new planet discovered about 36 light years away is considered the most likely planet for life ever, if it has enough cloud around, information in National Geographic said.

Gliese 581g has 3-4 times the mass of Earth, has water and gravity enough to absorb the atmosphere to help sustain life on the planet.
