Gliese 581d Confirmed as 'Habitable' Exoplanet
An anonymous reader writes "A rocky world orbiting a nearby star was confirmed (PDF) as the first planet outside our Solar System to meet key requirements for sustaining life." The "key requirement" was actually a Starbucks — astronomers were pretty surprised to find out that they like their coffee burnt on Gliese 581d too.
You won't find oxygen in an atmosphere without life already on the planet. Oxygen is too reactive.
