Just 20 light years away: Scientists discover first planet outside our solar system that could support Earth-like life

A planet 20 light years away is the first outside our solar system to be officially declared habitable by scientists.

The 'exoplanet' Gliese 581d has conditions that could support Earth-like life, including possible watery oceans and rainfall.

Yet any future space voyagers landing there would find themselves in truly alien surroundings. The sky is likely to be murky red, not blue, and gravity is twice what is on Earth, doubling the weight of anyone standing on the surface.

In addition, the planet's carbon dioxide-rich atmosphere would almost certainly not be breathable by humans.

Scientists were surprised by the discovery because Gliese 581d was previously ruled out as a habitable planet candidate.

But a new computer model capable of simulating extraterrestrial climates has shown the previous assumption to be wrong, and confirmed that Gliese 581d really could harbour life.
