Watching Solar Activity Muddle Earth's Magnetic Field Paris, France (ESA) May 05, 2009 
Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes affect orbiting satellites, including the GPS system.
The results were obtained from coordinated in-situ measurements performed by ESA's four Cluster satellites along with the two Chinese/ESA Dou ... read more

NASA's Fermi Explores High-Energy "Space Invaders"
Washington DC (SPX) May 05, 2009Since its launch last June, NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars, probed gamma-ray bursts and watched flaring jets in galaxies billions of light-years away. At the American Physical Society meeting in Denver, Colo., Fermi scientists have revealed new details about high-energy particles implicated in a nearby cosmic mystery. "Fermi's Large Area Telesc ... more The Asteroids Are Coming 
Bethesda MD (SPX) May 04, 2009This isn't just "buzz" to get you excited about a new movie coming; we really are being buzzed by asteroids and other NEOs (Near Earth Objects), and one day these conjunctions could become collisions! There are lots of NEOs out there orbiting the sun. Some, like comets, are less worrisome since they are composed primarily of ice and small, rocky particles that dissipate upon entering Earth ... more Magnesium Detected During Second Flyby Of Mercury 
Baltimore MD (SPX) May 05, 2009NASA's MESSENGER spacecraft served up another curveball to a University of Colorado at Boulder team after a second flyby of the hot inner planet Oct. 6 detected magnesium - an element created inside exploding stars and which is found in many medicine cabinets on Earth - clumped in the tenuous atmosphere of the planet. Scientists had suspected magnesium would be present, but were surprised ... more Comets Contain Key Ingredients For Life On Earth 
Tel Aviv, Israel (SPX) May 05, 2009Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. Now Tel Aviv University justifies our fascination - comets might have provided the elements for the emergence of life on our planet. While investigating the chemical make-up of comets, Prof. Akiva Bar-Nun of the Department of Geophysics and Pl ... more IMAX-3D Camera To Film Hubble Servicing Mission 
Washington DC (SPX) May 05, 2009NASA, the IMAX Corporation and Warner Bros. Pictures have announced that IMAX 3-D cameras will return to space to document one of NASA's most complex space shuttle operations: the final servicing mission to the Hubble Space Telescope. The IMAX 3-D cameras will launch aboard space shuttle Atlantis, which is scheduled to lift off May 11. Astronauts will use the cameras to film five spacewalk ... more |

Washington DC (SPX) May 04, 2009The global citizen-science campaign GLOBE at Night 2009 recorded 80 percent more observations of the world's dark skies than the program's previous record - including double the number of digital measurements - thanks in large part to active participation and publicity from the network of 140 countries currently celebrating the International Year of Astronomy 2009 (IYA2009). Now in its fou ... more NIST Super-Sensors To Measure Signature Of Inflationary Universe 
Washington DC (SPX) May 04, 2009What happened in the first trillionth of a trillionth of a trillionth of a second after the Big Bang? Super-sensitive microwave detectors, built at the National Institute of Standards and Technology (NIST), may soon help scientists find out. The new sensors, described at the American Physical Society (APS) meeting in Denver, were made for a potentially ground-breaking experiment by a ... more Making The Space Environment Safer For Civil And Commercial Users 
Washington DC (SPX) May 04, 2009The House Committee on Science and Technology's Subcommittee on Space and Aeronautics held a hearing to examine the challenges faced by civil and commercial space users as space traffic and space debris in Earth orbit continue to increase. Subcommittee Members questioned witnesses about potential measures to improve the information available to civil and commercial users to avoid in-space ... more Gamma Signature, Astronomer's Telegram Cast Light On Dazzling Blazar 
Menlo Park CA (SPX) May 04, 2009When it comes to watching the skies, two sets of eyes are always better than one, especially if one pair can see, say, radio waves, while the other has X-ray or even gamma-ray vision. The Fermi Gamma-Ray Space Telescope's Large Area Telescope collaboration has recently released a paper giving the gamma-ray perspective on an astronomical object that flared last summer, an active galactic nu ... more |

Paris, France (ESA) May 01, 2009One of the last activities to take place in S5B is the filling of the Herschel cryostat with liquid helium and its conversion into superfluid helium-II. The primary objective of achieving a full cryostat, above 95%, with a helium temperature below 1.7 Kelvin was reached on Friday 25 April and the activities now focus on maintaining the good helium conditions until the spacecraft can be mov ... more Some planets may fall into their stars 
Seattle, April 29, 2009 U.S. astronomers say some of the hundreds of planets that once orbited stars outside our solar system may have fallen into their stars and no longer exist. University of Washington astronomer Rory Barnes says recent computer modeling has provided the first evidence gravitational forces might pull a planet into its parent star. "When we look at the observed properties of extrasola ... more Duke Physicists See The Cosmos In A Coffee Cup 
Durham NC (SPX) Apr 20, 2009A Duke University professor and his graduate student have discovered a universal principle that unites the curious interplay of light and shadow on the surface of your morning coffee with the way gravity magnifies and distorts light from distant galaxies. They think scientists will be able to use violations of this principle to map unseen clumps of dark matter in the universe. Light ... more Search on for Toronto-area meteorite bits 
Toronto, April 29, 2009 Canadians living north and northeast of Toronto are being asked to help search for meteorite fragments from a fireball last month. In a release, the Royal Ontario Museum in Toronto and the University of Western Ontario in London said analysis of a network of sky camera footage shows a slow-moving fireball swept eastward on March 15 at 8:37 p.m. near the small city of Newmarket.
