Giant Ribbon At The Edge Of The Solar System: Mystery SolvedHuntsville AL (SPX) Jan 18, 2010 Last year, when NASA's IBEX (Interstellar Boundary Explorer) spacecraft discovered a giant ribbon at the edge of the solar system, researchers were mystified. They called it a "shocking result" and puzzled over its origin. Now the mystery may have been solved. "We believe the ribbon is a reflection," says Jacob Heerikhuisen, a NASA Heliophysics Guest Investigator from the University of Alabama in Huntsville. "It is where solar wind particles heading out into interstellar space are reflec ... read more |

The Difference Between Ganymede And Callisto
Boulder CO (SPX) Jan 26, 2010Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to research by scientists at the Southwest Research Institute appearing online in Nature Geoscience Jan. 24, 2010. Ganymede and Callisto are similar in size and are made of a similar mi ... more Star Formation Gets Crazy And Cool
East Lansing, MH (SPX) Jan 26, 2010"Crazy" and "cool" are two of the words Michigan State University astronomer Megan Donahue uses to describe the two distinct "tails" found on a long tail of gas that is believed to be forming stars where few stars have been formed before. Donahue was part of an international team of astronomers that viewed the gas tail with a very long, new observation made by the Chandra X-ray Observatory ... more Groovy Hills Rising From Titan Surface
Pasadena CA (JPL) Jan 26, 2010Hills with a wrinkly radial pattern stand out in a new radar image captured by NASA's Cassini spacecraft on Dec. 28, 2009. The grooved mounds in the picture, which are located in a northern hemisphere region known as Belet, are about 80 kilometers (50 miles) wide and about 60 meters (200 feet) high. The shapes of these landscape features have not been seen on Titan before, though the ... more |

The First Of Many Asteroid Finds For WISEPasadena CA (JPL) Jan 25, 2010 NASA's Wide-field Infrared Survey Explorer, or WISE, has spotted its first never-before-seen near-Earth asteroid, the first of hundreds it is expected to find during its mission to map the whole sky in infrared light. The near-Earth object, designated 2010 AB78, was discovered by WISE Jan. 12. After the mission's sophisticated software picked out the moving object against a background of stationary stars, researchers followed up and confirmed the discovery with the University of Hawaii's 2.2-meter ... read more |
