Water Planet Discovered Only 40 Light Years Away
Jackpot.
“But extraordinary may be too understated a descriptor for the discovery reported on Wednesday in the journal Nature: an international team led by Harvard astronomer David Charbonneau has spotted a “super-Earth,” a planet 2.7 times bigger than Earth, circling a dim red star called GJ 1214, just 40 light-years away in the constellation Ophiuchus. “It’s spectacular,” says Geoffrey Marcy of the University of California, Berkeley, who is the world’s most prolific planet hunter and is credited with discovering 70 of the first 100 exoplanets. “It’s a top-of-the-top discovery in the quest for Earth-size planets.”
