 Lunar orbiters discover source of space weather near Earth Los Angeles CA (SPX) Oct 02, 2013 - Solar storms - powerful eruptions of solar material and magnetic fields into interplanetary space - can cause what is known as "space weather" near Earth, resulting in hazards that range from interference with communications systems and GPS errors to extensive power blackouts and the complete failure of critical satellites. New research published today increases our understanding of Earth' ... more |  |
SUNRISE Offers New Insight on Sun's Atmosphere Greenbelt MD (SPX) Oct 02, 2013 - Three months after the flight of the solar observatory Sunrise - carried aloft by a NASA scientific balloon in early June 2013 - scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere. Sunrise provided the highest-resolution images to date in ultraviolet light of this thin corrugated layer ... more |  |
 Astronomers Uncover a 'Transformer' Pulsar Greenbelt MD (SPX) Oct 02, 2013 - An international team of scientists using a fleet of orbiting X-ray telescopes, including NASA's Swift and Chandra X-ray Observatory, has discovered a millisecond pulsar with a dual identity. In a feat that has never before been observed, the star readily shifts back and forth between two mutually exclusive styles of pulsed emission - one in X-rays, the other in radio. The discovery, say s ... more |  |
Jekyll and Hyde star morphs from radio to X-ray pulsar and back again Charlottesville, VA (SPX) Oct 02, 2013 - Astronomers have uncovered the strange case of a neutron star with the peculiar ability to transform from a radio pulsar into an X-ray pulsar and back again. This star's capricious behavior appears to be fueled by a nearby companion star and may give new insights into the birth of millisecond pulsars. "What we're seeing is a star that is the cosmic equivalent of 'Dr. Jekyll and Mr. Hyde,' ... more |  |
Magnetic field may shape "blooming" star Narrabri, Australia (SPX) Oct 02, 2013 - An old star, IRAS 15445-5449, has begun to push out a jet of charged particles that glow with radio waves. A few old stars are known to have jets, "but this is the first one where the radio waves tell us the jet is held together by a strong magnetic field", said Dr Jessica Chapman of CSIRO Astronomy and Space Science, a member of the research team. "That's a clue to what makes these jets s ... more |  |

Observations reveal critical interplay of interstellar dust, hydrogen Madison WI (SPX) Oct 02, 2013 - For astrophysicists, the interplay of hydrogen - the most common molecule in the universe - and the vast clouds of dust that fill the voids of interstellar space has been an intractable puzzle of stellar evolution. The dust, astronomers believe, is a key phase in the life cycle of stars, which are formed in dusty nurseries throughout the cosmos. But how the dust interacts with hydrogen and ... more |  |
 3-D models of electrical streamers Washington DC (SPX) Oct 01, 2013 - Streamers may be great for decorating a child's party, but in dielectrics, they are the primary origin of electric breakdown. They can cause catastrophic damage to electrical equipment, harm the surrounding environment, and lead to large-scale power outages. Understanding streamers and the mechanisms behind their initiation, acceleration and branching is necessary to devise better solutions to a ... more |  |
 People prefer different robot faces depending on task assigned Atlanta (UPI) Oct 1, 2013 - People have varying opinions about what a personal robot should look like, and they change their minds based on what it is supposed to do, U.S. researchers say. In a study at the Georgia Institute of Technology, participants were shown photos of either robotic, human or mixed human-robot faces and asked to choose the one that they would prefer for a robot's appearance. While most ... more |  |
 Tokyo gadget show offers glimpse of tomorrow Chiba, Japan (AFP) Oct 01, 2013 - A car that drives itself and glasses that translate a menu as you read it are some of the glimpses of tomorrow on offer at a gadget fair near Tokyo that began on Tuesday. The Cutting-Edge IT & Electronics Comprehensive Exhibition (CEATEC) threw open its doors to thousands of visitors eager to sample the gizmos they will be using in future. The highlight for many is Japanese carmaker Niss ... more |  |

 Astronomers create first cloud map of distant planet Pasadena, Calif. (UPI) Oct 1, 2013 - U.S. astronomers say data from NASA space telescopes have allowed them to create the first cloud map of a planet beyond our solar system. The cloud map of Kepler-76, a hot, Jupiter-sized planet, was built up from observations by the Kepler and Spitzer space telescopes, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Monday. "By observing this planet with Spitzer an ... more |  |
 Bright, laser-based lighting devices Washington DC (SPX) Oct 01, 2013 - As a modern culture, we crave artificial white lights - the brighter the better, and ideally using less energy than ever before. To meet the ever-escalating demand for more lighting in more places and to improve the bulbs used in sports stadiums, car headlights and street lamps, scientists are scrambling to create better light-emitting diodes (LEDs) - solid state lighting devices that are more ... more |  |
Study of big-bang radiation may yield clues to early universe Paris (UPI) Oct 1, 2013 - Telescopes on Earth and in space have detected a subtle twist in the radiation from the big bang and the first moments of the universe, astronomers say. Observers using telescopes in Antarctica and the European Space Agency's Herschel Space Observatory found the signal of the "twist" in the way the first light in the universe has been deflected by intervening galaxy clusters and dark ma ... more |  |
 US spy chief defends 'noble' mission, denounces leaks Washington (AFP) Sept 25, 2013 - The head of the National Security Agency Wednesday defended US surveillance programs as part of a "noble" mission to protect the nation and said reports on them were "sensationalized." "The future of this country depends on our ability to defend against cyber attacks and terrorist threats, and we need the tools to do it," said General Keith Alexander, chief of the NSA. The agency heads t ... more |  |
 UFO? Star cluster? No, it's Falcon 9's jettisoned fuel Vandenberg Air Force Base, Calif. (UPI) Sep 30, 2013 - The Falcon 9 launch from California not only boosted the cache of commercial spaceflight but also of UFO sightings, a review of observers' comments indicated. Reports of an unidentified flying object flowed in from observers in southern Africa and several islands in the Indian Ocean, NBC News reported Monday. The sightings began about an hour after the SpaceX's Falcon 9 v1.1 rock ... more |  |

 Martian chemical complicates hunt for life's clues Washington DC (SPX) Oct 01, 2013 - The quest for evidence of life on Mars could be more difficult than scientists previously thought. A scientific paper published today details the investigation of a chemical in the Martian soil that interferes with the techniques used by the Curiosity rover to test for traces of life. The chemical causes the evidence to burn away during the tests. In search of clues to life's presence on M ... more |  |
Scientists find a martian igneous rock that is surprisingly Earth-like Pasadena CA (JPL) Oct 01, 2013 - During the nearly 14 months that it has spent on the red planet, Curiosity, the Mars Science Laboratory (MSL) rover, has scooped soil, drilled rocks, and analyzed samples by exposing them to laser beams, X-rays, and alpha particles using the most sophisticated suite of scientific instruments ever deployed on another planet. One result of this effort was evidence reported last March that ancient ... more |  |
Researchers describe unusual Mars rock Corvallis OR (SPX) Oct 01, 2013 - The first rock that scientists analyzed on Mars with a pair of chemical instruments aboard the Curiosity rover turned out to be a doozy - a pyramid-shaped volcanic rock called a "mugearite" that is unlike any other Martian igneous rock ever found. Dubbed "Jake_M" - after Jet Propulsion Laboratory engineer Jake Matijevic - the rock is similar to mugearites found on Earth, typically on ocean ... more |  |
