Solar System older than thoughtParis (AFP) Aug 22, 2010 The Solar System could be nearly two million years older than thought, according to a study published on Sunday by the journal Nature Geoscience. The evidence comes from a 1.49-kilo (3.2-pound) meteorite, found in the Moroccan desert in 2004, that contains a "relict" mineral, which is one of the oldest solid materials formed after the birth of the Sun. Analysis of lead isotopes suggest the mineral was formed 4.45682 billion years ago, making the meteorite the oldest object ever found. As a r ... read more |

Pasadena CA (JPL) Aug 19, 2010NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio. The flyby on August 13 targeted the geyser moon Enceladus, but also brought Cassini close to two other moons--Tethys and Dione. The raw images include the best ones to date of Penelope crater on the icy moon Tet ... more  
Sydney, Australia (SPX) Aug 19, 2010Before the end of 2010, China will have launched its second lunar probe. Chang'e 2 is an orbiting spacecraft that was originally built as a back-up for China's first lunar probe, Chang'e 1, which flew to the moon in 2007. The launch is widely tipped for some time in October. Sending the back-up spacecraft on its own mission makes sense. The spacecraft was already built, and the integrity o ... more  
Laurel MD (SPX) Aug 19, 2010The Johns Hopkins University Applied Physics Laboratory (APL), with help from Boeing and Iridium Communications, has successfully implemented a new space-based system to monitor Earth's space environment. Known as the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE), the system provides real-time magnetic field measurements using commercial satellites as part ... more |

Evidence Of New Solar Activity From Observations Of Aurora In NZBoston MA (SPX) Aug 16, 2010 Scientists from Boston University's Center for Space Physics (CSP) has announced that they have sub-visual evidence of the onset of a new cycle of solar-terrestrial activity. The key results being reported deal with the fact that recent auroral displays at high latitudes (ones visible to the naked eye) were accompanied by far less luminous glows in the atmosphere at lower latitudes. "It's exciting to see the return of aurora to mid-latitudes," Dr. Steve Smith said, referring to the periodic occurr ... read more |
