Plasma found at black hole
Astronomers report they have detected remarkably stormy conditions in the hot plasma being pulled into the monstrous black hole residing at the center of our Milky Way galaxy, 26,000 light years away.
Hubble assists Europe's Rosetta comet mission
Results from the Hubble Space Telescope played a major role in preparing ESA's ambitious Rosetta mission for its new target, comet 67P/Churyumov-Gerasimenko. Hubble has been the critical tool in measuring precisely the size, shape and rotational period of the comet. Information that is essential if Rosetta is to rendezvous with a comet and then drop down a probe.
Weather appears promising for Monday's Titan launch
Delayed from August due to technical issues, a Titan 4 rocket carrying a classified national security payload is scheduled for liftoff Monday night from Cape Canaveral, Florida. The exact launch time is a secret. The weather forecast predicts favorable conditions.

Antimatter factory on Sun yields clues to explosions
The best look yet at how a solar explosion becomes an antimatter factory gave unexpected insights into how the tremendous explosions work. The observation may upset theories about how the explosions, called solar flares, create and destroy antimatter. It also gave surprising details about how they blast subatomic particles to almost the speed of light.
Grunsfeld succeeds Lucid as NASA chief scientist
Administrator Sean O'Keefe has announced the selection of veteran astronaut, astronomer, and astrophysicist Dr. John Grunsfeld as the agency's new Chief Scientist at NASA Headquarters in Washington. He succeeds Dr. Shannon Lucid, effective immediately. Lucid will return to the Johnson Space Center in Houston to assist the agency's Return to Flight efforts.
SIRTF begins snapping test images of Universe
NASA's Space Infrared Telescope Facility has switched on two of its onboard instruments and captured some preliminary star-studded images. The space observatory was launched from Cape Canaveral, Fla., on August 25.

Mysterious 'giant domes' of Europa could be explained
A new University of Colorado at Boulder study of Jupiter's moon Europa may help explain the origin of the giant ice domes peppering its surface and the implications for discovering evidence of past or present life forms there.
New image of Comet Halley out in the cold
Seventeen years after the last passage of Comet Halley, the Very Large Telescope in Chile has captured a unique image of this famous object as it cruises through the outer solar system. It is completely inactive in this cold environment.

Major flares on far-away stars said predictable
For the first time, astronomers are able to predict when major flares-enormous explosions that shoot hot gases into space-will erupt on stars outside our solar system, according to research to be published in the Astrophysical Journal.
NASA: Tides control flow of Antarctic ice streams
The moon is often accused of causing lunacy, bringing on labor and transforming werewolves. Now it seems that in reality, the moon, through the tides, is responsible for the pattern of motion exhibited by ice streams in the Antarctic, according to a team of geologists from NASA, Penn State and University of Newcastle, Newcastle Upon Tyne, England.
