Gliese 581 is a red dwarf star about 20 light-years ... rotated were mimicking not only planets f and g but also planet d, which suspiciously had a claimed orbital period half that of the star's ...

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 planet Gliese 581 d might be habitable. However, the environmental conditions on planet d might be too harsh to allow complex life to appear. Planet d is tidally locked, like the Moon in our ...

Scientists believe Gliese 581 is old — at least a few billion years ... Michael worked as a herpetologist and wildlife biologist. He has a Ph.D. in evolutionary biology from the University ...

But the team responsible for the study noticed something suspicious about d’s period. The star, Gliese 581, rotates about every 130 days, making planet d’s period very close to half of the ...

Gliese 581 d als Ersatz-erdähnlich? Eher sei der ebenfalls 2007 entdeckte Gliese 581 d ein Kandidat im lebensfreundlichen Umfeld. Er sei jedoch mit etwa 8 Erdmassen nur noch bedingt vergleichbar ...

Astronomen haben um den Roten Zwergstern Gliese 581 zwei weitere Planeten entdeckt. Damit steigt die Zahl der bekannten Planeten in diesem System auf sechs. Einer der neu entdeckten Planeten, GJ 581g, ...

Gliese 581 d, was in the prime habitable zone for potential life. "The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'" said Michel ...

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 ...

Immerhin wurde Exoplanet Gliese 581-b bestätigt, die Signale von Gliese 581-c und -e haben sich sogar noch verstärkt. Der Planet 581-d ist mit sehr hoher Wahrscheinlichkeit einem Rotationseffekt des ...

This part interests me, because I've run into similar situations myself. If you tell your computer that one of the planets (in this case, Gliese 581 d) has a highly elliptical orbit, then Gliese 581 g ...

In 2010, exoplanet hunters announced that they'd potentially found just such a planet. Twenty light-years away, orbiting the star Gliese 581, was a rocky planet thought to be three to four times ...
