New results from the Stardust space probe, which collected dust from the tail of a comet and returned it to Earth, show material similar to that found close to the sun rather than pristine material left over from the formation of the solar system.

 | University of Arkansas researchers are receiving a grant to examine material from a comet sample brought back to Earth from outer space. They will try to determine its composition and age. This work will provide new insights into the formation and history of comets. ...> Full Article |
 | Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials. ...> Full Article |
 | Samples of the material picked up during the NASA Stardust mission indicate that parts of the comet Wild 2 actually formed in an area close to the sun. ...> Full Article |
 | Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. After testing helium and neon trapped in the dust specks, Pepin and his colleagues report that while the comet formed in the icy fringes of the solar system, the dust appears to have been born close to the infant sun and bombarded by intense radiation from these and other gases before being flung out beyond Neptune and trapped in the comet. ...> Full Article |
A scientist with The University of Arizona Lunar and Planetary Laboratory will discover more about comets and Earth's moon, thanks to spacecraft on extended and new NASA missions.

 | Comet 17P/Holmes, which dazzled sky watchers with a dramatic outburst that made it visible to the unaided eye, now is fading from sight. However, before it returns to the obscurity from which it came, astronomers at the MMT Observatory took a final look. ...> Full Article |
 | Formerly, the Sun was the largest object in the Solar System. Now, comet 17P/Holmes holds that distinction. ...> Full Article |
UC Davis physics professor J. Anthony Tyson will testify before Congress on Thursday, Nov. 8, on near-Earth asteroids. Tyson will talk about the potential role of the proposed Large Synoptic Survey Telescope (LSST) in surveying the sky for objects that might eventually strike our planet. The hearing of the House Committee on Science and Technology will begin at 10 a.m. in room 2318 of the Rayburn Office Building.

 | ESA's comet chaser, Rosetta, is on its way to its second close encounter with Earth on 13 November. The spacecraft's operators are leaving no stones unturned to make sure Earth's gravity gives it the exact boost it needs en route to its destination. ...> Full Article |
Comet 17P/Holmes may be old, but it can still kick up its heels and go dancing with the stars! It was discovered more than 100 years ago, and since then has made 16 loops around the Sun. It should have fizzled long ago, but just this week Comet Holmes surprised sky watchers with a stunning outburst, becoming brighter than any comet in the past decade.

 | A once-faint comet has made a sudden leap from obscurity to center stage. Comet 17P/Holmes, now visible to northern hemisphere residents, increased its brightness by a factor of one million this week, going from magnitude 17 to 2. This makes it visible to the unaided eye as well as binoculars and telescopes, offering a unique viewing opportunity for sky watchers. ...> Full Article |

 | Echoing the re-discovery of America by the Spanish long after an earlier Viking reconnaissance, astronomers have learned that a recently observed asteroid - one that could potentially hit the Earth - was actually first observed nearly a half-century ago. Researchers at the Minor Planet Center of the Smithsonian Astrophysical Observatory in Cambridge, MA have confirmed work by SETI Institute astronomer Peter Jenniskens that the recently discovered asteroid 2007 RR9 is in fact the long-lost object 6344 P-L. ...> Full Article |
 | Comets are made of the most primitive stuff in the solar system. As hunks of rock and ice that never coalesced into more planets, they give researchers clues to the evolution of solar systems. ...> Full Article |
 | It is nothing new for the ESA/NASA Solar and Heliospheric Observatory (SOHO) to discover another comet - it has already found more than 1350. But the latest is a bit different - SOHO had spotted it twice before. ...> Full Article |
 | The traditional belief that Jupiter acts as a celestial shield, deflecting asteroids and comets away from the inner Solar System, has been challenged by the first in a series of studies evaluating the impact risk to the Earth posed by different groups of object. ...> Full Article |
