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 ...

Earth-like planets may be common A simulation study provides hope for finding habitable extrasolar planets.Amanda Gefter By Astronomy Staff | Published: December 22, 2003 | Last updated on May 18 ...

Most exoplanets orbit other stars like Earth does with our sun, but free-floating exoplanets (or rogue planets) orbit the galactic center and are untethered to any star.

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, ...

"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.

Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like exoplanets could be more common than we thought.
