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....

Astronomers Find New Planets And A Mystery Object Outside Our Solar System
2011-10-27 13:04:07

Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer. Using the Hobby-Eberly Telescope, astronomers observed the planets' parent stars -- called HD 240237, BD +48 738, and HD 96127 -- tens of light years away from our solar system. One of the massive, dying stars has an additional mystery object orbiting it, according to team leader Alex Wolszczan, an Evan Pugh Professor of Astronomy and...

An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in...

Astronomers at the European Southern Observatory (ESO) have discovered five planets orbiting a star in what is being called by the AFP news agency "the biggest discovery of so-called exoplanets since the first was logged 15 years ago." The ESO astronomers discovered the planetary system around a sun-like star called HD 10180. Using the HARPS spectrograph, they also reportedly discovered evidence which suggests that there may be two additional planets present in orbit around the celestial...

Scientists have opportunity to watch a planetary "death march" An international group of astrophysicists has determined that a massive planet outside our Solar System is being distorted and destroyed by its host star "“ a finding that helps explain the unexpectedly large size of the planet, WASP-12b. It's a discovery that not only explains what's happening to WASP-12b; it also means scientists have a one-of-a-kind opportunity to observe how a planet enters this final stage of its life....

An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate. Their findings are published in December's first issue of the journal Astronomy and Astrophysics. These super-massive black holes at the center of galaxies are called active galactic nuclei. For the first time, the team observed a quasar with an active galactic nucleus, as part of the group of four, which...

Astronomers are announcing today that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting the young binary star system V4046 Sagittarii. The SMA images provide an unusually vivid snapshot of the process of formation of giant planets, comets, and Pluto-like bodies. The results also confirm that such objects may just as easily form around double stars as around single stars like our Sun. These...

On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunter's sword, the Orion Nebula swaddles a cluster of newborn stars called the Trapezium. These stars are young but powerful, each one shining with the brilliance of 100,000 Suns. They are also massive, containing 15 to 30 times as much material as the Sun. Where did the Trapezium stars come from? The question is not as simple as it seems. When it comes to the theory of how massive stars form,...

A team of French astronomers has captured one of the sharpest color images ever made. They observed the star T Leporis, which appears, on the sky, as small as a two-storey house on the Moon [1]. The image was taken with ESO's Very Large Telescope Interferometer (VLTI), emulating a virtual telescope about 100 meters across and reveals a spherical molecular shell around an aged star. "This is one of the first images made using near-infrared interferometry," says lead author Jean-Baptiste Le...
