WASHINGTON, April 17, 2014 /PRNewswire-USNewswire/ -- Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. http://photos.prnewswire.com/prnvar/20081007/38461LOGO While planets...

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...

Astronomers Given A Better Ruler In The Search For Extrasolar Planets
2014-03-31 08:04:47

NIST Researchers at the National Institute of Standards and Technology (NIST) have rejuvenated a technique for finding planets near distant stars. New measurements of light from special lamps could help astronomers find planets hidden in data from more than a decade's worth of extrasolar planet searches, as well as improve telescopes' current capabilities. Finding extrasolar planets is tricky. Seen through a telescope, planets in the "habitable zone"—a region close to a star, where...

Lick's Automated Planet Finder Has Found Two New Planetary Systems

By Tim Stephens, UC Santa Cruz In its first months of operation, the APF has found two new planetary systems, giving astronomers a taste of planetary riches to come Lick Observatory's newest telescope, the Automated Planet Finder (APF), has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets. Every night the fully autonomous system checks the weather, decides which stars to observe, and moves the telescope from star...

[ Watch the Video: Artist’s Impression of Ring System Around Chariklo ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time. Chariklo sits about 1.2 billion miles out in the solar system between Saturn and Uranus, and the minor planet, or asteroid, has been known about for many years. However, this is the first time astronomers discovered...

Watch The Video: Studying Other Worlds with the Help of a Starshade ] Whitney Clavin, NASA's Jet Propulsion Laboratory A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif. The hunt is on for planets that resemble Earth in size, composition and temperature. Rocky...

Mars Craters for Cash

redOrbit Staff & Wire Reports - Your Universe Online Bad news for those who spent $5 to have a Mars crater named after themselves, a significant other or a beloved pet: the International Astronomical Union (IAU) confirmed on Tuesday that those purchased names will not be allowed to appear on official maps and globes. The naming program, announced last month by science advocacy start-up Uwingu, allowed users to go online and pay $5 for the right to place a moniker on one of the...

NASA's WISE Spacecraft Has Yet To Uncover Planet 'X' Beyond Pluto

redOrbit Staff & Wire Reports - Your Universe Online While NASA’s Wide-Field Infrared Survey Explorer (WISE) has uncovered thousands of new stars during its multi-year mission, it has been unable to collect any evidence supporting the supposed existence of a large but unseen celestial body believed to be located somewhere beyond Pluto’s orbit. This supposed celestial body is commonly referred to as “Planet X” -- alternatively “Nemesis” or “Tyche." However, despite the...

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 -- 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...
