The search for extraterrestrial life is one of the most exciting frontiers of modern science. Thanks to recent discoveries of exoplanets like Gliese 581 g, Kepler-22 b, Kepler-186 f, and Kepler-452 b, ...

But Gliese 581 c and d could very well be big icy planets, with a very different composition from the Earth. [2] The team led by F. Selsis (CRAL and LAB, France) includes J.F. Kasting ...

Both teams found that, while Gliese 581 c is too close to the star to be habitable, the planet Gliese 581 d might be habitable. However, the environmental conditions on planet d might be too harsh ...

At that pace, it would take 766,000 years to get to Gliese 581 g—that’s more than three times longer than homo sapiens have been around. Even if we had the technology to go faster, the energy ...

Following the latest estimation, Gliese 581 would be 7 Gyr-old. The purple bars surrounding planets Gliese 581 c and d illustrate the variable distance to the star caused by the eccentricity of ...

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 ...

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.

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.

Where there's water, there's the possibility of life. It just so happens that H2O acts as an ideal medium for chemical reactions between organic molecules, helping them link together to form amino ...

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 ...
