New supercomputer simulations tracking the interactions of thousands of dust grains show what the solar system might look like to alien astronomers searching for planets. The models also provide a glimpse of how this view might have changed as our planetary system matured. "The planets may be too dim to detect directly, but aliens studying the solar system could easily determine the presence of Neptune -- its gravity carves a little gap in the dust," said Marc Kuchner, an astrophysicist at...

A picture is worth a thousand words, or so University of California, Berkeley, astronomer Paul Kalas found out when he published a Hubble Space Telescope image of a Jupiter-sized planet orbiting the star Fomalhaut. Since it appeared in the journal Science in November 2008, "the image of Fomalhaut, its visually striking belt of comet dust and its planet has become an iconic image of a planetary system," said Kalas, an adjunct associate professor of astronomy at UC Berkeley. National Geographic...

There might be one hundred billion Earth-like planets in our galaxy, US scientists announced at a recent press conference. Dr Alan Boss of the Carnegie Institution of Science stated that maybe a few of these could have simple life forms living on them. Boss announced this at the yearly meeting of the American Association for the Advancement of Science in Chicago. Thus far, telescopes have found 300 planets outside our solar system. However, only a few would be able to support life. The...

NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star. Estimated to be no more than three times Jupiter's mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis (the Southern Fish). Fomalhaut has been a candidate for planet hunting ever since an excess of dust was discovered around the star in the early 1980s by NASA's Infrared Astronomy Satellite...

A young star's strange elliptical ring of dust likely heralds the presence of an undiscovered Neptune-sized planet, says a University of Rochester astronomer in the latest Monthly Notices of the Royal Astronomical Society. Stars in the early stages of life are surrounded by dust clouds that thin out and dissipate as the star reaches maturity, becoming rings in their final stages. One star, however, has a dust ring that has long puzzled astronomers because it is not centered around the star as...

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...

Berkeley - Astronomers zooming in on a nearby star with NASA's Hubble Space Telescope have discovered unmistakable evidence of a planetary system: a perturbed dusty belt around the star that's analogous to the vast Kuiper Belt of icy rocks encircling the sun. While the discovery is expected to send astronomers scurrying to their telescopes to obtain direct images of a planet around the star, called Fomalhaut, it also provides a Rosetta stone for debris disks - the pancakes of rock and ice...

NASA -- The Hubble Space Telescope's most detailed visible-light image ever taken of a narrow, dusty ring around the nearby star Fomalhaut (HD 216956), offers the strongest evidence yet that an unruly and unseen planet may be gravitationally tugging on the ring. Hubble unequivocally shows that the center of the ring is a whopping 1.4 billion miles (15 astronomical units) away from the star. This is a distance equal to nearly halfway across our solar system. The most plausible explanation,...
