Chuck Bednar for redOrbit.com - Your Universe Online Using observations from the NASA’s Hubble Space Telescope, a team of astronomers has managed to create the most detailed map ever of an exoplanet’s air temperature and water vapor, officials from the US space agency announced Thursday. The target of the investigation, which is detailed in the October 9 edition of Science Express, was WASP-43b - a hot-Jupiter exoplanet said to have winds that travel the speed of sound, a ‘day’...

WASHINGTON, Oct. 9, 2014 /PRNewswire-USNewswire/ -- A team of scientists using NASA's Hubble Space Telescope has made the most detailed global map yet of the glow from a turbulent planet outside our solar system, revealing its secrets of air temperatures and water vapor. http://photos.prnewswire.com/prnVAR/20081007/38461LOGO Hubble observations show the exoplanet, called WASP-43b, is no place to call home. It is a world of extremes, where seething winds howl at the speed of sound from a...

In a feat of long-distance detection, astronomers led by experts at the University of Maryland have found water vapor in the atmosphere of a Neptune-sized planet nearly 729 trillion miles from Earth. This is the smallest planet for which scientists have been able to identify chemical components of its atmosphere. (PRWEB) September 24, 2014 Astronomers have found water vapor in the atmosphere of a planet about four times bigger than Earth, in the constellation Cygnus about 124 light years...

extrasolar planet HAT-P-11b
2014-09-24 13:40:24

NASA Astronomers using data from three of NASA's space telescopes -- Hubble, Spitzer and Kepler -- have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system. The planet is about the size of Neptune, making it the smallest planet from which molecules of any kind have been detected. [ Watch the Video: Zoom Into HAT-P-11 ] “This discovery is a significant milepost on the road to eventually analyzing the atmospheric composition of smaller, rocky...

exoplanet WASP-18b
2014-09-16 13:43:14

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 star, WASP-18, and its planet, WASP-18b, are located about 330 light-years from Earth. WASP-18b has a mass about 10 times that of Jupiter and completes one orbit around its star in less than 23 hours, placing WASP-18b in the “hot Jupiter” category...

exoplanet sun wobble
2014-09-16 04:19:22

April Flowers for redOrbit.com - Your Universe Online It would seem like a star couldn't be affected by anything less than another star, but new evidence from Cornell University reveals that "hot Jupiters," or large gaseous exoplanets, can cause their host stars to wobble as the planets wind their way through their own solar systems to snuggle up against their suns. "Although the planet's mass is only one-thousandth of the mass of the sun, the stars in these other solar systems are...

gas giant planet HD 209458b
2014-07-24 07:35:40

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...

super earth Kepler-93b
2014-07-24 03:00:38

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...

Kepler-421b
2014-07-22 05:09:31

April Flowers for redOrbit.com - Your Universe Online The time that it takes for a planet, or planetary satellite, to orbit its star is considered the planet's year. For example, Earth's year is approximately 365 days, while Mercury's is 88 days and Mar's year is 687 days long. A group of astronomers working at the Harvard-Smithsonian Center for Astrophysics (CfA) has discovered a transiting exoplanet, named Kepler 421b, with the longest known year of any of the 1,800 exoplanets...

newly discovered planet in binary system
2014-07-04 04:31:19

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
