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 ...

Second, once the ship got to Gliese 581 g, we’d have no way to slow it down. Third, if the ship drifted out of the laser’s path, the crew would be lost, because it would be years before we ...

The boundaries are shown for several possible ages (5, 7, and 9 Gyr-old) of the Gliese 581 planetary system. Following the latest estimation, Gliese 581 would be 7 Gyr-old.

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-g is only 20 light years away. How long does that take, anyway? The possibility of life on other planets has been a staple of science fiction for decades.

Gliese 581 g shot to the top of a list put out by researchers at the University of Puerto Rico at Arecibo’s Planetary Habitability Laboratory (PHL) after a new study marshaled support for its ...

Last time we wrote about the possibly-habitable exoplanets orbiting red dwarf star Gliese 581 was back when we were possibly lie in the habitable zone. 581c lies in a questionably-habitable spot ...

Gliese 581d, an exoplanet (planet outside our solar system) seven times the size of Earth, orbits a star called Gliese 581 that is 20 light-years away in the constellation Libra. When it was first ...

Gliese 581 and its “Goldilocks zone”–the orbiting range wherein habitable planets are neither too close nor too far from their star to support life–have received a good deal of attention ...

The Geneva team plugged the HARPS data on Gliese 581 into computer models to check on the odds the signal was the result of noise, rather than evidence of the habitable planet g as claimed by the ...
