Earlier this week, a team of astronomers at the European Southern Observatory (ESO) discovered three new planets orbiting our neighboring star Gliese 667C (appx. 22 light-years from Earth) in the so-called habitable zone, once again raising hopes that they could have liquid water--one of the key ingredients for supporting life. With the latest additions to the recent string of discoveries, there are now at least twelve planets and 26 moons in our neighboring galaxies that could become our future homes, according to the Habitable Exoplanets Catalog.
