Exoplanet Orbiting Tau Bootis Star Could Have Watery Atmosphere
2014-02-25 11:14:09

[ Watch the Video: Watery Evidence Found In Tau Bootis System ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing a paper in The Astrophysical Journal Letters, say they may have discovered water on an exoplanet outside our solar system. The team of scientists say they believe they have detected water in the atmosphere of a planet orbiting the nearby star tau Boötis. "Planets like tau Boötis b, which are as massive as Jupiter but much hotter, do not...

A census of planets outside our solar system pierces the haze surrounding five "hot Jupiters" to find conclusive signs of atmospheric water. College Park, Md (PRWEB) December 03, 2013 Using the powerful eye of NASA's Hubble Space Telescope, two teams of scientists have found faint signatures of water in the atmospheres of five distant planets. The presence of atmospheric water was reported previously on a few exoplanets – planets orbiting stars beyond our solar system....

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...
