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...

Exoplanet Search Techniques Needs To Be Refined

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

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

[ 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...

WASHINGTON, Sept. 30, 2013 /PRNewswire-USNewswire/ -- 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. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) 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...

[ Watch the Video: The Strange Attraction of Hot Jupiters ] redOrbit Staff & Wire Reports - Your Universe Online The number of exoplanets discovered by astronomers since the beginning of the Space Age some five decades ago suggests there are possibly over 100 billion such worlds outside our solar system, according to one Caltech astronomer involved with NASA’s Kepler mission. According to John Johnson, an assistant professor of astronomy at the Pasadena-based university, over...

Chandra Eyes An Eclipsing Planet
2013-07-30 04:21:13

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time. A team writing in The Astrophysical Journal said they used the X-ray observatory to detect the exoplanet passing in front of its parent star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led...
