New Earth-like planet discovered: “Astronomers have discovered a potentially habitable planet of similar size to Earth in orbit around a nearby star.
A team of planet hunters spotted the alien world circling a red dwarf star called Gliese 581, 20 light years away.
The planet is in the “Goldilocks zone” of space around a star where surface temperatures are neither too hot nor too cold for liquid water to form…” (via The Guardian.)
Alien planets: otherwordly joys: “The rocky planet freshly identified in orbit around the star Gliese 581 could indeed be a potential home for life, but nobody should contemplate relocation just yet. At speeds possible with rocket technology, a voyage to Gliese 581, in the constellation Libra, would take about 200,000 years. As a home away from a home, it won’t work. But the planet now known as Gliese 581 g is a reminder of the extraordinary rewards of astronomy.” (via Comment is free | guardian.co.uk.)
