Stardust Found In Distant Planetary Systems

Astronomers of the University Jena find a stardust belt in extra-solar planetary systems The debris discs are remnants of the formation of the planets. "We are dealing with enormous accumulations of chunks of matter which create dust when they collide", Alexander Krivov says. This dust is of greatest importance for the astronomers, because it helps to draw conclusions about the planet formation. There are even two debris discs in our solar system, the asteroid belt and the Kuiper belt...

Extreme Weather Found On Alien World

  Cosmic oddball may harbor a gigantic storm A University of Toronto-led team of astronomers has observed extreme brightness changes on a nearby brown dwarf that may indicate a storm grander than any seen yet on a planet. Because old brown dwarfs and giant planets have similar atmospheres, this finding could shed new light on weather phenomena of extra-solar planets. As part of a large survey of nearby brown dwarfs — objects that occupy the mass gap between dwarf stars and...

  A team of scientists at Germany´s Max-Planck Institute for Astronomy has discovered a potentially habitable planet about 3.6 times as massive of Earth orbiting the star HD 85512, roughly 36.23 light years away (one light year is equivalent to roughly 5.9 trillion miles). Dan Vergano of USA Today reports that the discovery, led by the institute´s Lisa Kaltenegger, adds to the 572 planets orbiting nearby stars listed by the Extrasolar Planets Catalogue. Astronomers around...

Astronomers said on Thursday that they have discovered the darkest known exoplanet they say is the size of Jupiter. The researchers said exoplanet, TrES-2b, is blacker than coal or any planet or moon in our solar system. "TrES-2b is considerably less reflective than black acrylic paint, so it's truly an alien world," astronomer David Kipping of the Harvard-Smithsonian Center for Astrophysics (CfA), lead author on the paper reporting the research, said in a statement. TrES-2b lacks reflective...

The French-led CoRoT (Convection, Rotation and planetary Transits) satellite has found ten new planets outside our Solar System. The new find brings the total number of known exoplanets to 561.  CoRoT launched in 2006 and it spots planets by measuring the tiny dip in stellar light that occurs when planets pass between the stars and the Earth. The spacecraft has added 23 planetary systems to the roster so far. CoRoT went into orbit shortly after NASA's Kepler, which is a similar...

In a new model of the early solar system, Jupiter is found to have been a youthful traveler, roaming as close to the Sun as where Mars is now and back out again before settling in its position as the fifth planet from our Sun. Scientists note that the planet's travels greatly influenced the solar system, altering the asteroid belt and making Mars smaller than it should have been. The model was developed by an international team of scientists and was published in the journal Nature on June...

NASA's Kepler spacecraft is proving itself to be a prolific planet hunter. Within just the first four months of data, astronomers have found evidence for more than 1,200 planetary candidates. Of those, 408 reside in systems containing two or more planets, and most of those look very different than our solar system. In particular, the Kepler systems with multiple planets are much flatter than our solar system. They have to be for Kepler to spot them. Kepler watches for a planet to cross in...

NASA said on Wednesday that astronomers have discovered a new class of Jupiter-sized planets floating alone in space. The astronomers believe these worlds were probably ejected from developing planetary systems. A Japan-New Zealand joint survey scanned the center of the Milky Way galaxy during 2006 and 2007, revealing evidence for up to 10 free-floating planets about the size of Jupiter.  "Although free-floating planets have been predicted, they finally have been detected, holding...

Scientists said on Monday that a rocky planet outside our solar system is the first to meet key requirements for sustaining life. Modeling of planet Gliese 581d shows that it has the potential to be warm and wet enough to nurture Earth-like life. The planet orbits on the outer fringes of the star's "Goldilocks zone," where it is not so hot that water boils away, nor so cold that water is perpetually frozen.  "With a dense carbon dioxide atmosphere -- a likely scenario on such a large...

IRVING, Texas, April 1, 2011 /PRNewswire/ -- On March 30th, an incident was detected where a subset of Epsilon clients' customer data were exposed by an unauthorized entry into Epsilon's email system. The information that was obtained was limited to email addresses and/or customer names only. A rigorous assessment determined that no other personal identifiable information associated with those names was at risk. A full investigation is currently underway. SOURCE Epsilon

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...
