ESA steps up search for Earth-like planets

The European Space Agency (ESA) has awarded funding to a project aimed at identifying Earth-like planets that could be capable of supporting life.

Earthlike planets unlikely in systems with hot Jupiters

Solar systems with so-called hot Jupiters don't seem to harbor Earth-sized planets, a discovery that will narrow the search for Earth-like worlds.

Earth-like planets probably common, say astronomers

Earth-sized planets could be ten a penny, say UC Berkeley astronomers, who estimate they may orbit as many as a quarter of all Sun-like stars.
