NASA's Chandra X-ray Observatory Finds Planet That Makes Star Act Deceptively Old

NASA A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA’s Chandra X-ray Observatory. This discovery shows how a massive planet can affect the behavior of its parent star. The...

J.D. Harrington, NASA Headquarters, Washington Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the sun -- and have come up nearly dry. The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates for detecting water vapor in their atmospheres because of their high temperatures where water turns...

Whitney Clavin, Jet Propulsion Laboratory Thanks to NASA's Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 kilometers) on either side of the planetary body. [ Watch: ScienceCasts: Sizing Up An Exoplanet ] The findings confirm Kepler-93b as a "super-Earth" that is about one-and-a-half times...

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

[ 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...

WASHINGTON, Dec. 31, 2013 /PRNewswire-USNewswire/ -- Scientists using NASA's Hubble Space Telescope have characterized the atmospheres of two of the most common type of planets in the Milky Way galaxy and found both may be blanketed with clouds. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The planets are GJ 436b, located 36 light-years from Earth in the constellation Leo, and GJ 1214b, 40 light-years away in the constellation Ophiuchus. Despite numerous efforts,...

New Hubble Data Offer More Details About Cloudy Alien World

[ Watch the Video: New Secrets Revealed About Cloudy Exoplanet ] Lee Rannals for redOrbit.com - Your Universe Online Scientists using data collected by the Hubble Space Telescope have discovered new cloudy details about an alien world. The team said that GJ1214b is a super-Earth class planet because its mass is intermediate between Earth and Neptune. The group of scientists analyzed the characteristics of the exoplanet and published their results in the journal Nature. Previous...

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....

Five Alien Worlds With Water Detected By Hubble Space Telescope
2013-12-03 14:19:52

[ Watch the Video: Water That's Out Of This World Detected By Hubble ] Lee Rannals for redOrbit.com - Your Universe Online NASA said its Hubble Space Telescope has detected subtle traces of water in the atmospheres of five distant alien worlds. Two teams of scientists have discovered faint signatures of water in the atmospheres of five exoplanets. This is the first study to conclusively measure and compare the profiles and intensities of these signatures on multiple worlds. "We're...

Diamond Planet Not So Precious After All
2013-10-09 04:42:18

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...
