Arlington, Va. – The world’s preeminent planet hunters have discovered the most Earth-like extrasolar planet yet: a possibly rocky world about 7.5 times as massive as the Earth. This hot ...

Do earth-like planets in close orbits around low-mass stars have magnetic fields strong enough to shield them from both their own star’s incoming radiation and galactic cosmic rays? The short ...

Meet GJ 1214b, the most Earth-like planet ever found outside our solar system. It’s not exactly Earth’s twin: It’s about six times bigger, a whole lot hotter and made mostly of water. But ...

The extrasolar planet is about 150 light-years away, 1.5 times the size of Earth, and closely orbits its host star in about 45 days.

When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared ...

For most of his career, Geoff Marcy never thought he'd find any extrasolar planets. But that's all changed. Marcy is one of the lead astronomers sifting through the Kepler data, and has been ...

"The analysis of all the stars studied with HARPSshows that about one third of all solar-like stars have either super-Earth orNeptune-like planets with orbital periods shorter than 50 days." ...

In a long-awaited milestone, astronomers using a NASA space telescope have found a roughly Earth-size world, Kepler-22b, orbiting around a sun-like star where conditions may be favorable for life.
