Superhabitable Exoplanet
2014-01-24 11:27:06

[ Watch the Video: Are Some Exoplanets More Super Than Earth? ] Brett Smith for redOrbit.com - Your Universe Online The stellar habitable zone (SHZ), or Goldilocks zone, is considered the range of ideal orbital distances from a star for creating the conditions necessary for life. A new paper published recently in the journal Astrobiology argues that some planetary bodies outside this zone may hold environments even more habitable for life than those found here on Earth. The authors...

Exoplanet Discovered Thanks To Its Orbit Around A Bright Star
2014-01-23 04:41:44

redOrbit Staff & Wire Reports - Your Universe Online An international group of astronomers has discovered a new, roughly Neptune-sized exoplanet orbiting the brightest star in a binary system more than 400 light years from Earth, according to a study appearing in the most recent edition of The Astrophysical Journal. The study authors, who were working out of the Stellar Astrophysics Centre in Denmark, found the new planet by studying the star around which it revolves. They...

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 Exoplanet Pisces
2014-01-10 07:43:23

redOrbit Staff & Wire Reports - Your Universe Online A team of astronomers led by Stephen Kane of San Francisco State University (SFSU) has discovered a new giant planet that could have twice the mass of Jupiter. The new planet is located in a star system within the Pisces constellation, and could help scientists gain new insight into how extrasolar planets, or exoplanets, are formed. This new star system contains just one star, as do three other systems containing extrasolar...

New Technique Measures Exoplanet Composition
2014-01-09 09:59:15

redOrbit Staff & Wire Reports - Your Universe Online Scientists have successfully measured the masses of approximately 60 exoplanets discovered by the Kepler space telescope – research that will help them determine the composition of these planets and ultimately whether or not they are capable of supporting life. Their findings, which were presented Monday during the 223rd annual meeting of the American Astronomical Society (AAS) in Washington, DC, covered planets located outside...

Super Earths May Be More Like Our Planet Than Previously Theorized
2014-01-09 06:55:52

[ Watch the Video: More Like Earth? Exoplanet Scientists Weight In ] Brett Smith for redOrbit.com - Your Universe Online It seems like the discovery of Earth-like planets is always announced with one caveat – the planet discovered probably isn’t much like Earth. Many of these are "super-Earths," several times larger than our own planet and thought to be completely covered in water. However, a new study to be published in an upcoming edition of the Astrophysical Journal, has...

Habitable Zone Larger Than Believed
2014-01-08 14:32:50

[ Watch the Video: Life In The Habitable Zone ] Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the journal Planetary and Space Science claims planets that were once thought uninhabitable may actually be able to contain life after all. University of Aberdeen scientists say that earth-sized planets are able to support life at least ten times farther away from stars than previously thought. This idea challenges the traditional 'habitable zone' theory...

Gemini Planet Imager Tracks Down Giant Planet Orbiting Beta Pictoris
2014-01-07 13:47:41

Brett Smith for redOrbit.com - Your Universe Online The internationally operated Gemini Observatory has announced the start-up of its new Gemini Planet Imager (GPI), a device designed to capture images of planets outside our Solar System and probe their atmospheres. The imager, which released its first image on Tuesday, was deployed on the observatory’s 8-meter Gemini South telescope in Chile. "Even these early first-light images are almost a factor of 10 better than the previous...

Exoplanet Gassy Earth
2014-01-07 09:54:01

John P. Millis, PhD for redOrbit.com - Your Universe Online The holy grail of planet hunting is to find the first Earth-like world. While candidates have been found, there has yet to be confirmation about their particular characteristics. However, a new discovery, made possible by an international team of astronomers, has located the first confirmed Earth-mass planet occulting -- that is, passing in front of -- its host star. Even though the tiny world has the same mass as our planet,...

Rocky Exoplanets Too Hot To Support Life: Kepler Data
2014-01-07 05:07:34

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Kepler spacecraft team reported details about five new rocky planets on Monday at the American Astronomical Society meeting in Washington. Kepler has helped scientists discover hundreds of exoplanets, and astronomers at the event reported on four years of follow-up observations, as well as describing the new rocky planets discovered. According to the latest findings, Kepler-99b and Kepler-406b are 40 percent larger in size...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

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...
