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...

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the more interesting questions in astronomy surrounds how solar system objects actually form. Astronomers are particularly concerned about the boundary between a planet and a star. When examining the objects in our own solar neighborhood, the question seems trivial – the Sun dominates the mass of our system, while even the largest planet, Jupiter, is dwarfed by comparison. In other parts of the galaxy, stars exist that...

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...

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...

Sunny Outlook For NASA Kepler's Second Light
2013-11-26 12:09:10

NASA You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae. In May, the Kepler spacecraft lost the second of four gyroscope-like reaction wheels, which are used to precisely point the...

Scientists Meet To Discuss 833 New Exoplanets
2013-11-04 16:21:02

Lee Rannals for redOrbit.com - Your Universe Online An international group of scientists are gathering for the second Kepler Science Conference this week at NASA’s Ames Research Center in Moffett Field, California. Researchers will be discussing the latest findings from the Kepler Space Telescope data, which includes the discovery of 833 new candidate planets. Ten of the new exoplanets are less than twice the size of Earth and orbit in the habitable zone. New Kepler data shows that...

NASA will video stream a news briefing at 10:15 a.m. PST (1:15 p.m. EST) Monday, Nov. 4, to announce new results from the agency's Kepler mission. The briefing, taking place during the Kepler Science Conference, will be in building 152 at NASA Research Park in Moffett Field, Calif. With its 2009 launch, Kepler became the first NASA mission capable of finding Earth-sized planets in or near the habitable zone -- the region around a star in which orbiting planets may have surface temperatures...

Explanet Same Size As Earth
2013-10-30 16:15:10

Brett Smith for redOrbit.com - Your Universe Online In August, an international team of researchers announced the discovery of a planet outside our solar system - also referred to as an exoplanet - that orbits its star in just 8.5 hours and is roughly the same size as Earth. Now, the same research team members that found the planet, dubbed Kepler 78b, have made another startling discovery: the planet’s mass is roughly the same as our own. "This planet is a complete mystery," said...

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...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Solar Nebula -- In astronomy, the solar nebula is the gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed...

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...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...
