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.

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 ...

They used 238 separate observations of Gliese 581 taken over a period of 11 years. Haghighipour said that the team is keeping tabs on many nearby stars using the Keck Observatory.

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.

Astronomers say temperatures on their newly-discovered planet Gliese 581c are within the range in which water would be liquid. It’s circling an unremarkable red dwarf star called Gliese 581, and ...
