Free-Floating Planet Identified By Astronomers
2012-11-14 06:50:44

[ Watch the Video: Artists Impression of Free-Floating Planet ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified a body that is most likely a planet wandering throughout space without a parent star. The free-floating planet candidate is the closet such object to the Solar System observed so far, lying at a distance of about 100 light-years away. Astronomers using the European Space Observatory's Very Large Telescope (VLT) and the Canada-France-Hawaii...

Goldilocks Zone Serves Up Another Super Earth

[ Watch the Video: New Habitable Zone Super-Earth Found in ExoSolar System ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Mankind´s fascination with the possibility of life on other worlds has been a mainstay of science fiction for more than a century. But it wasn´t until the last decade that we possessed the technology to begin searching in earnest for habitable planets outside of our solar system. While the tally of new worlds has seen a surge...

Zombie Planet Interview With Dr Thayne Currie
2012-11-02 14:22:24

Dr. John Millis and Jedidiah Becker for redOrbit.com — Your Universe Online In 2008, astronomers announced that the Hubble Space Telescope had captured images of an alien planet orbiting the nearby star Fomalhaut, located a mere 25 light years away in the constellation Piscis Austrinus. Dubbed Fomalhaut b and claimed as the first exoplanet to be confirmed through direct imaging in visible light, the planet appeared to orbit its star immersed in a massive ring of dust and debris....

Kepler Data Helps Find Compact Planetary System
2012-10-16 05:40:51

Lee Rannals for redOrbit.com - Your Universe Online Scientists have found one particular planetary system that crams five planets into a region less than one twelfth the size of the Earth's orbit. Dr. Darin Ragozzine, a postdoctoral researcher at the University of Florida, reported the team's findings of KOI-500 at a meeting of the American Astronomical Society's Division for Planetary Sciences. The planetary system is about 1,100 light-years away in the constellation Lyra, also called...

Planetary Systems Compared To Pancakes
2012-10-15 12:14:06

Lee Rannals for redOrbit.com - Your Universe Online Astronomers from UCLA using NASA's Kepler space telescope have determined that most planetary systems are "flatter than pancakes." The team wrote in a paper submitted to the Astrophysical Journal that they developed a computer model of planetary systems and compared them to the properties of Kepler data. They found that the more than 85 percent of planets have inclinations of less than three degrees, making the planetary systems...

Olivine Found In Beta Pictoris
2012-10-04 05:20:13

April Flowers for redOrbit.com - Your Universe Online European Space Agency's (ESA) Herschel Space Observatory has discovered pristine material that matches comets in our own Solar System in a dust belt around the young star Beta Pictoris. Beta Pictoris is 12 million years old, and resides a short 63 light-years from Earth. A gas giant planet and a dusty debris disc that has the potential to evolve into a torus of icy bodies like those of the Kuiper Belt found outside the orbit of...

Exoplanet Found Within Gliese 163 Habitable Zone
2012-09-05 13:54:45

Michael Harper for redOrbit.com — Your Universe Online Good news! The ESO´s HARPS telescope (or High Accuracy Radial Velocity Planet Searcher) team has found a potentially habitable planet around the red dwarf star Gliese 163! This brings the number of known, potentially habitable planets to 6, most of which have been discovered in the past year. This rocky planet, called Gliese 163c, is considered a superterran, or super-Earth, and is a considerable 50 light years away from...

NASA’s Kepler Space Telescope Discovers Two Planets Orbiting Binary Star System
2012-08-29 08:58:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers working with NASA´s Kepler mission have found the first evidence of multiple planets orbiting a binary star system. The discovery shows that planetary systems can form and survive in chaotic environments around a binary star system. Furthermore, the discovery suggests that earth-like planets can also exist in the habitable zone of their stars. The discovery was announced this week at the XXVIII General Assembly of...

Star Caught Consuming Its Own Planet
2012-08-21 11:41:35

Lee Rannals for redOrbit.com - Your Universe Online Astronomers say they've witnessed the death of a planet, which found its journey ended by way of its own star. The scientists reported in the Astrophysical Journal Letters that BD+48 740 became a red giant at the end of its life, helping it to eventually consume its close-by planet. "A similar fate may await the inner planets in our solar system, when the sun becomes a red giant and expands all the way out to Earth's orbit some 5...

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...

'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
