Massive Ring Of Carbon Monoxide Discovered In Turbulent Comet Field
2014-03-07 10:10:00

[ Watch the Video: Colliding Comets Hint At Unseen Exoplanet ] Brett Smith for redOrbit.com - Your Universe Online NASA scientists have found evidence of a highly-turbulent comet field circling a star 63 light years from Earth. This cosmic shooting gallery has produced a massive ring of carbon monoxide gas and dust that also encircles the star, according to a new report published in the journal Science. According to the report authors, the comet field is probably the result of either...

WASHINGTON, Feb. 26, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized...

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...

Planet's Wild Ride Caught By Kepler Space telescope
2014-02-05 05:09:28

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Kepler space telescope has located a new planet that wobbles wildly on its axis much like a spinning toy top, with its tilt varying by as much as 30 degrees over an 11 year span, the US space agency announced Tuesday. The planet, which has been named Kepler-413b, follows an unusual 66-day orbit around a binary system comprised of an orange and red dwarf star. The planet, which is located 2,300 light-years away in the...

WASHINGTON, Feb. 4, 2014 /PRNewswire-USNewswire/ -- Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child's top. The tilt of the planet's spin axis can...

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...

[ 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 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...

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...
