Gliese 12b, an Earth-sized exoplanet that’s only 40 light years away, ... You had mentioned before whether or not we could actually travel to this planet, Gliese 12 b.

The Gliese 581 star has about 30 percent the mass of our sun, and the outermost planet is closer to its star than we are to the sun. Gliese 581d might be able to sustain liquid water on its surface.

Gliese 581: Extrasolar Planet Might Indeed Be Habitable Date: December 14, 2007 Source: Astronomy & Astrophysics Summary: In April, a European team of astronomers announced the discovery of two ...

The Gliese 581 star has about 30 percent the mass of our sun, and the outermost planet is closer to its star than we are to the sun. Gliese 581d might be able to sustain liquid water on its surface.

A rocky alien planet called Gliese 581d may be the first known world beyond Earth capable of supporting life as we know it, a new study suggests. Astronomers performing a new atmospheric-modeling ...

A&A is now publishing two independent, detailed studies of this system, which confirm that one of the planets might indeed be located within the habitable zone around the star Gliese 581. Advanced ...

So scanning Gliese 581g's atmosphere, if it has one, would give us a good idea if the planet harbors life or not. But it'll probably be a few decades before we can do this properly.

The planet orbits a so-called cool red dwarf star called Gliese 12, according to NASA. Gliese 12 is only about 27% of the sun’s size, with about 60% of the sun’s surface temperature, NASA said.

A newly discovered alien planet may be one of the top contenders to support life beyond Earth, researchers say. The newfound world, a "super Earth" called Gliese 163c, lies at the edge of its star ...

Gliese 12 b is one of “a handful of temperate planets similar to Earth that are both close enough to us and meet other criteria needed for this kind of study,” said Michael McElwain, a ...

Nearly two years after spotting Gliese 581g, the celebrated "first potentially habitable" alien world, the planet's discoverers continue to fight for its existence. IE 11 is not supported.
