Astronomers Discover The "Mega-Earth"
2014-06-02 03:30:17

Harvard-Smithsonian Center for Astrophysics Astronomers announced on Monday that they have discovered a new type of planet - a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldn't form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas giant. This planet, though, is all solids and much bigger than previously discovered "super-Earths," making it a "mega-Earth." "We were very surprised when we realized what we had...

Exoplanet Orbiting Tau Bootis Star Could Have Watery Atmosphere

redOrbit Staff & Wire Reports - Your Universe Online What was believed to be the first planet discovered to be comprised largely of diamond most likely does not have a high content of the precious mineral after all, according to new research scheduled for publication in in the Astrophysical Journal. The planet, which is located approximately 40 light years from our solar system, was first analyzed in 2010. At the time, it was concluded that the world had a surface of graphite...

Patchy Clouds On Exotic World Found By NASA Space Telescopes
2013-10-01 09:19:03

NASA's Jet Propulsion Laboratory Astronomers using data from NASA's Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b. The planet is marked by high clouds in the west and clear skies in the east. Previous studies from Spitzer have resulted in temperature maps of planets orbiting other stars, but this is the first look at cloud structures on a distant world. "By observing this...
