Earth-like planet found

A small rocky planet has been found orbiting a normal star outside our solar system. Astronomers said that this is the most earth-like planet ever found. Although rocky like the Earth, the planet is too cold to support life. From
The planet is estimated to be about 5.5 times as massive as Earth and thought to be rocky. It orbits a red dwarf star about 28,000 light-years away. Red dwarfs are about one-fifth as massive as the Sun and up to 50 times fainter. But they are among the most common stars in the universe...

It was discovered using a technique called “gravitational microlensing,” whereby light from a distant star is bent and magnified by the gravitational field of a foreground star. The presence of a planet around the foreground star causes light from the distant star to become momentarily brighter.

No life on that planet? Damnit! Aren't we getting lonelier everyday in this universe? Hehe.
