New focus on the moon
NASA's Lunar Reconnaissance Orbiter Camera has taken and received its first images of the Moon, kicking off the year-long mapping mission of Earth's nearest celestial neighbor. The LROC imaging system is under the watchful eyes of Arizona State University professor Mark Robison, the principal investigator.

LRO's first moon images
NASA's Lunar Reconnaissance Orbiter has transmitted its first images since reaching the moon on June 23. The spacecraft's two cameras, collectively known as the Lunar Reconnaissance Orbiter Camera, or LROC, were activated June 30. The cameras are working well, and have returned images of a region in the lunar highlands south of Mare Nubium (Sea of Clouds).

Many characteristics of Mars, including ice, are similar to Earth, paper says
Mars gets as far as 250 million miles away, but many parts of it closely resemble places on Earth, including its landscape, history of water, soil and even its weather, says a Texas A&M University researcher in the current issue of Science magazine.

Pinpointing origin of gamma rays from a supermassive black hole
An international collaboration of 390 scientists reports the discovery of an outburst of very-high-energy gamma radiation from the giant radio galaxy Messier 87, accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole. The combined results give first experimental evidence that particles are accelerated to extremely high energies of tera electron Volt in the immediate vicinity of a supermassive black hole and then emit the observed gamma rays.

Astronomer's new guide to the galaxy: Largest map of cold dust revealed
Astronomers have unveiled an unprecedented new atlas of the inner regions of the Milky Way, our home galaxy, peppered with thousands of previously undiscovered dense knots of cold cosmic dust -- the potential birthplaces of new stars. Made using observations from the APEX telescope in Chile, this survey is the largest map of cold dust so far, and will prove an invaluable map for observations made with the forthcoming ALMA telescope, as well as the recently launched ESA Herschel space telescope.

University of Hawaii at Manoa astronomers discover pair of solar systems in the making
Two University of Hawaii at Manoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system. Doctoral student Rita Mann and Dr. Jonathan Williams used the Submillimeter Array on Mauna Kea, Hawaii, to make the observations.

Largest ever survey of very distant galaxy clusters completed
An international team of researchers led by Gillian Wilson, an astronomer at the University of California, Riverside, has completed the largest ever survey designed to find very distant clusters of galaxies. Named the Spitzer Adaptation of the Red-sequence Cluster Survey, "SpARCS" detects galaxy clusters using deep ground-based optical observations. SpARCS is designed to find clusters, snapped as they appeared long ago in time, when the universe was 6 billion years old or younger.

Hand-held aerosol sensors help fill crucial data gap over oceans
Since NASA researchers began assembling the Aerosol Robotic Network in the 1990s, the worldwide network of ground-based aerosol sensors has grown to 400 sites across seven continents. The trouble is that two-thirds of the planet is covered by ocean. And aerosols -- the tiny atmospheric particles that can have an outsized impact on the climate -- are just as likely to be found in the air above the oceans as they are over land.

From his office at NASA's Goddard Space Flight Center in Greenbelt, Md., Brent Holben helps manage the world's largest network of ground-based sensors for aerosols -- tiny specks of solids and liquids that waft about in the atmosphere. These particles come from both human and natural sources, and can be observed everywhere in the world.

Climate phenomenon influences England's chances in the Australian leg of the Ashes
The El Nino Southern Oscillation phenomenon has been shown to have a significant effect on the results of the Ashes cricket series. When the series is held in Australia, the Australian Cricket team is more likely to succeed after El Nino years, while the England cricket team has a historically better record following La Nina years (the opposite phase), according to a study published today in Weather.

Milky Way's super-efficient particle accelerators caught in the act
Thanks to a unique "ballistic study" that combines data from ESO's Very Large Telescope and NASA's Chandra X-ray Observatory, astronomers have now solved a long-standing mystery of the Milky Way's particle accelerators. They show in a paper published today on Science Express that cosmic rays from our galaxy are very efficiently accelerated in the remnants of exploded stars.

Space shuttle science shows how 1908 Tunguska explosion was caused by a comet
The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research. The conclusion is supported by an unlikely source: the exhaust plume from the NASA space shuttle launched a century later.

New detectors for nuclear, radiological material in cargo should not be acquired until testing deficiencies fixed, cost-benefit analysis completed
A thorough cost-benefit analysis that includes an assessment of meaningful alternatives is needed to reveal the potential security advantages of deploying new detector systems to screen cargo for nuclear and radiological materials at US ports and border crossings. It is likely that the costs will exceed the savings gained from improved efficiency of the screening systems, says a new report from the National Research Council.

Magnetic field on bright star Vega
Astronomy & Astrophysics publishes the first detection of a magnetic field on the bright star Vega. Using the NARVAL spectropolarimeter of the Bernard-Lyot telescope on top of the Pic du Midi (France), astronomers clearly observe the magnetically-induced effect in the spectrum of Vega, thereby showing that the star possesses a magnetic field, something unknown so far.
