Discovery expands search for Earth-like planets: Newly spotted frozen world orbits in a binary star system

A newly discovered planet is expanding astronomers’ notions of where Earth-like—and even potentially habitable—planets can form, and how to find them. At twice the mass of Earth, the planet orbits one of the stars in the binary system at almost exactly the same distance from which Earth orbits the sun. However, because the planet’s host star is much dimmer than the sun, the planet is much colder thanEarth — a little colder, in fact, than Jupiter’s icy moon Europa.
