Earth-like planet found 20 light years away

Astronomers at the Geneva Observatory in Switzerland have discovered an Earth-like planet with favourable surface temperatures (0-40C) for life.

It orbits Gliese 581 in the Libra constellation, and is a mere 20 light-years away, with a size of 1.5 Earths (does it say how much of a sci-fi geek I am that I automatically wrote "1.5 Earth norm" as the description for its size?) This is the same team that has been making other planetary discoveries (mostly gas giants due to the accuracy of available measurements) on distant solar systems. It seems their system keeps getting more and more refined.

How I missed this back when it was first published, I have no idea.
