Earth-like planet

NASA confirms the first Earth-like planet

Astronomers with NASA's Kepler mission have confirmed the existence of an Earth-like planet in a “habitable zone” outside our solar system.

Earth-like planet may, may not exist

Washington -- The announcement by U.S. astronomers of an Earth-like planet that could possibly support life circling another star has hit a slight bump -- it may not exist.

Researchers led by the Observatory of Geneva in Switzerland had already discovered four planets circling the star Gliese 581 by observing subtle motions of the star that are induced by the gravitational tugs of any orbiting planets when an American team announced a fifth, believed large enough to hold an atmosphere and the right distance from its star to allow for liquid water, ScienceMag.org reported.

But the original Swiss team says it can find no reliable evidence of a fifth planet in Gliese 582's habitable zone.

Another Earth exists outside our solar system, astronomers say

For the first time stargazers have detected a rocky planet outside our solar system that can sustain life. Astronomers claim the newly discovered rocky planet has the most basic and essential conditions needed to support extraterrestrial life.
