Newfound super-Earth might support life, scientists say
Potentially habitable planet detected in triple-star system just 22 light-years away

A potentially habitable alien planet — one that scientists say is the best candidate yet to harbor water, and possibly even life, on its surface — has been found around a nearby star.

The planet is located in the habitable zone of its host star, which is a narrow circumstellar region where temperatures are neither too hot nor too cold for liquid water to exist on the planet's surface.

Here they come Interactive: The new solar system Pluto debate is about more than one little world Cosmic Log: Planets on the Web Interactive: The search for extrasolar planets "It's the holy grail of exoplanet research to find a planet around a star orbiting at the right distance so it's not too close where it would lose all its water and boil away, and not too far where it would all freeze," Steven Vogt, an astronomer at the University of California at Santa Cruz, told Space.com. "It's right smack in the habitable zone — there's no question or discussion about it. It's not on the edge, it's right in there."

Vogt is one of the authors of the new study, which was led by Guillem Anglada-Escudé and Paul Butler of the Carnegie Institution for Science, a private, nonprofit research organization based in Washington.

"This planet is the new best candidate to support liquid water and, perhaps, life as we know it," Anglada-Escudé said in a statement.

An alien super-Earth
The researchers estimate that the planet, called GJ 667Cc, is at least 4.5 times as massive as Earth, which makes it a so-called super-Earth.
