NASA Telescopes Find Clear Skies And Water Vapor On Exoplanet

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...

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...

Whitney Clavin, NASA Jet Propulsion Laboratory The New Mexico Exoplanet Spectroscopic Survey Instrument (NESSI) will soon get its first "taste" of exoplanets, helping astronomers decipher their chemical composition. Exoplanets are planets that orbit stars beyond our sun. NESSI got its first peek at the sky on April 3, 2014. It looked at Pollux, a star in the Gemini constellation, and Arcturus, in the Boötes constellation, confirming that all modes of the instrument are working....

2014 Carl Sagan Fellows
2014-04-03 03:00:40

NASA/JPL NASA has selected seven scientists as recipients of the 2014 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars. The primary goal of the fellowship program is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's Exoplanet Exploration...

ESO Researchers Discover Three New Planets In Messier 67
2014-01-15 08:46:20

[ Watch the Video: Messier 67 A Perfect Lab For Studying Planet Formation ] Gerard LeBlond for redorbit.com - Your Universe Online There have been more than one thousand planets confirmed outside our Solar System, but only a few are within star clusters. Using the European Southern Observatory’s (ESO) HARPS instrument, researchers have found three new planets in the star cluster Messier 67. Of these three newly discovered planets, two have been found orbiting stars similar to our sun....

New Technique Measuring Exoplanet Mass
2013-12-19 15:52:43

Lee Rannals for redOrbit.com - Your Universe Online A new technique developed by a team at MIT could help scientists determine the mass of exoplanets, using just their transmission spectra. Scientists have discovered more than 900 exoplanets outside our solar system so far, and more are being found every week. Hunting for exoplanets takes a combination of patience, the right equipment and technique. Space telescopes help keep watch for dimming starlight, indicating that an exoplanet...

Astronomer Helps Research Team See Misaligned Planets In Distant System
2013-10-17 16:04:40

Iowa State University Using data from NASA's Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their host star. Such tilted orbits had been found in planetary systems featuring a "hot Jupiter," a giant planet in a close orbit to its host star. But, until now, they hadn't been observed in multiplanetary systems without such a big interloping planet. The discovery is reported in...

The Hunt For Extraterrestrial Life On Cloudy Extra-Solar Planets
2013-09-26 11:05:19

Brett Smith for redOrbit.com - Your Universe Online An international research team has created a map of the clouds that ensconce Kepler 7b, a distant planet outside our solar system, according to reports published by The Astrophysical Journal and Astrophysical Journal Letters. The studies’ researchers said their findings are a step forward in determining which planets outside our Solar System, also known as exoplanets, can host extraterrestrial life. Kepler 7b orbits a Sun-like...

Wind And Clouds Play An Important Role In Hot Jupiter Atmospheres
2013-07-05 05:27:23

Lee Rannals for redOrbit.com - Your Universe Online Astronomers studying eight exoplanets falling into the "hot-Jupiter" class suggest winds and clouds play an important role in the atmospheric make up of these exotic planets. Hot-Jupiters are giant planets similar in size to Jupiter, but orbiting very close to their stars. Astronomers are able to detect which gases are present in their atmosphere by analyzing the spectrum of starlight filtered through the planet's atmosphere when it...

Electrifying Exoplanets With Stellar Winds
2013-06-04 11:10:37

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own. Small, rocky worlds orbiting a couple of astronomical units from the host star, with the gas giant planets orbiting farther out. After all, much effort had been given to explaining how a solar system such as ours would form. Only, this is not what has been found. Many solar systems are constructed...

Two New Exoplanets Confirmed
2013-04-30 05:08:49

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The newest addition to our planet-hunting arsenal, the HARPS spectrograph, has characterized two new worlds. Planets KOI-200 b and KOI-889 b are Jupiter-like planets that orbit very close to their host stars. With periods of less than 10 days, the so-called “Hot Jupiters” were originally detected using NASA´s Kepler spacecraft. This instrument has documented more than 800 new exoplanets, with thousands...
