WASP Gives NASA's Planetary Scientists New Observation Platform
2014-02-09 08:10:00

April Flowers for redOrbit.com – Your Universe Online High-altitude balloons have long been used by scientists who study the Earth, the sun and the stars to gain a better view of their targets by carrying their telescopes far into the stratosphere. For planetary scientists, however, this doesn't work, as they need a highly stable, off-the-shelf type system that could accurately point their instruments and then track planetary targets as they move around in the solar system. Such a...

Kepler-16b
2014-02-10 05:15:24

NASA WASHINGTON, Feb. 6, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March. The National Space Club is recognizing Kepler for revolutionizing astrophysics and exoplanet science by expanding the census of planets beyond our solar system and fundamentally altering our understanding of our place in the Milky Way galaxy. The award citation acknowledges the...

Study Gives Insight Into How Skywalker's Tatooine May Have Formed
2014-01-31 13:03:26

Lee Rannals for redOrbit.com - Your Universe Online Tatooine, a fictional planet with two stars that is best known as the home of Luke Skywalker in the Star Wars movie franchise, may not be as farfetched as one might think. Scientists from the University of Bristol studied Tatooine’s real world counterparts: circumbinary planets. These planets, like Kepler-34(AB)b, have an orbit that encompasses two stars, and the latest study gives insight into what Skywalker’s home might have...

Brown Dwarf Weather Map
2014-01-29 13:17:01

Lee Rannals for redOrbit.com - Your Universe Online Scientists using the Very Large Telescope (VLT) at the European Southern Observatory created the world’s first map of the weather on the surface of a brown dwarf. The international team developed a map featuring the dark and light features of WISE J104915.57-531906.1B, which is the nearest brown dwarf to Earth. This brown dwarf, informally known as Luhman 16B, is one of two recently discovered brown dwarfs only six light years away...

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...

[ Watch the Video: ALMA Makes A Starry Cosmic Discovery ] redOrbit Staff & Wire Reports - Your Universe Online A team of Japanese astronomers has located evidence of a giant planetary system forming around a young star named HD142527, and their discovery could change existing theories on how planets form and provide new insights into the formation of a vast array of different planetary systems. Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, scientists...

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...

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...

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,...

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
