[ 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...

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers from the University of Arizona’s Department of Astronomy have managed to use an Earth-based telescope to capture images of a world outside of our solar system, according to research scheduled to be published in an upcoming edition of The Astrophysical Journal. The telescope used essentially the same type of imaging sensor found in a standard digital camera instead of an infrared detector, and while the...

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...

Astronomy & Astrophysics is publishing new observations of the giant planet around ÃŽ² Pictoris. Discovered in 2009, this planet, called ÃŽ² Pictoris b, has now been detected again with the NaCo instrument on the VLT. Astronomers find that the planet is moving around the star. They have also measured the mass and the effective temperature of ÃŽ² Pic b.Astronomy & Astrophysics publishes new high angular resolution observations of the...

UA astronomers have developed a way to see faint planets previously hidden in their star's glare. The new mode enables scientists to search for planets closer to the star than has been previously possible.Using new optics technology developed at the University of Arizona's Steward Observatory, an international team of astronomers has obtained images of a planet on a much closer orbit around its parent star than any other extrasolar planet previously found.The discovery, published online in...

For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves from one side of its host star to the other. The planet has the smallest orbit so far of all directly imaged exoplanets, lying almost as close to its parent star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. Because the star is so young, this discovery proves that gas giant planets can form within discs in...

A team of French astronomers using ESO's Very Large Telescope have discovered an object located very close to the star Beta Pictoris, and which apparently lies inside its disc. With a projected distance from the star of only 8 times the Earth-Sun distance, this object is most likely the giant planet suspected from the peculiar shape of the disc and the previously observed infall of comets onto the star. It would then be the first image of a planet that is as close to its host star as Saturn...

A harvest of low-mass exoplanets discovered with HARPS Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. Moreover, looking at their entire sample studied with HARPS, the astronomers count a total of 45 candidate planets with a mass below 30 Earth masses and an orbital...

With the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the Sun. The very extended and flared disc most likely contains enough gas and dust to spawn planets. It appears as a precursor of debris discs such as the one around Vega-like stars and thus provides the rare opportunity to witness the conditions prevailing prior to or during planet formation. "Planets form in massive, gaseous and dusty proto-planetary discs that...
