| Antarctic research helps shed light on climate change on Mars Thu, 28 Aug 2008 00:00:00 EDT |
(Boston University) Eroded gullies on the flanks of Martian craters may have been formed by snowmelt as recently as a few hundred thousand years ago and in sites once occupied by glaciers. Similar conditions can be found in Antarctica's McMurdo Dry Valleys. Rather than being a dead planet, the new data are consistent with dynamic climate changes on Mars. |
| Arctic ice on the verge of another all-time low Thu, 28 Aug 2008 00:00:00 EDT |
(European Space Agency) Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. |

Using the power of the sun for space travel propulsion will be the next leap forward in our journey to other worlds. The new book "Solar Sails" provides an accessible introduction to solar sails and details how they work and what they will be used for in the exploration of space. |
| UCI scientists discover minimum mass for galaxies Wed, 27 Aug 2008 00:00:00 EDT |

(NASA/Goddard Space Flight Center) NASA's newest observatory, the Gamma-Ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. |
| Utah steps into the heavens Tue, 26 Aug 2008 00:00:00 EDT |
(University of Utah) In its latest step to develop an astronomy program, the University of Utah is joining a major international effort to map the heavens as a way to search for giant planets in other solar systems, study expansion of the universe and probe the mysterious dark matter and dark energy that make up most of the universe. |
| New LIDAR system sees the sky in 3-D Tue, 26 Aug 2008 00:00:00 EDT |
(Ecole Polytechnique Fédérale de Lausanne) On Aug. 26, EPFL, the Swiss National Science Foundation and Switzerland's National Weather service, MeteoSwiss, will inaugurate a new LIDAR measurement system in Payerne, Switzerland. This technically innovative installation, unique in the world, will provide continuous data on atmospheric humidity for Western Switzerland's weather forecasting headquarters. |
| GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky Tue, 26 Aug 2008 00:00:00 EDT |
(DOE/US Department of Energy) The Department of Energy and NASA announced today that the Gamma-Ray Large Area Space Telescope has revealed its first all-sky map in gamma rays. The onboard Large Area Telescope's all-sky image -- which shows the glowing gas of the Milky Way, blinking pulsars and a flaring galaxy billions of light-years away -- was created using only 95 hours of "first light" observations, compared with past missions which took years to produce a similar image. |
| How do galaxies grow? Tue, 26 Aug 2008 00:00:00 EDT |
(ESO) Astronomers have caught multiple massive galaxies in the act of merging about 4 billion years ago. This discovery, made possible by combining the power of the best ground- and space-based telescopes, uniquely supports the favored theory of how galaxies form. |
| Inaugural Kavli Prize ceremony and symposia: Sept. 8-11 (Oslo, Norway) Tue, 26 Aug 2008 00:00:00 EDT |
(The Kavli Foundation) The inaugural year of the Kavli Prize will be celebrated with a special ceremony that features H.R.H. Crown Prince Haakon Magnus presenting the prize to the seven Kavli laureates. Acclaimed scientists in the fields of astrophysics, nanoscience and neuroscience will give lectures throughout the week. |
| Cloud in a chamber Mon, 25 Aug 2008 00:00:00 EDT |
(Goethe University Frankfurt) Everybody knows that clouds markedly influence weather and climate, but is this influence changing with time? Over the last several years some evidence was found that past changes in cosmic ray intensity have correlated with fluctuations of temperature and precipitation on Earth. There could be a causal link of these quantities via the formation of clouds, because the cosmic rays create ions in the atmosphere which may grow into aerosol particles that act as the initial point for cloud formation. |
| Improved satellite navigation for remote areas Sun, 24 Aug 2008 00:00:00 EDT |
(CSIRO Australia) CSIRO scientists with the Minerals Down Under National Research Flagship are working closely with industry and government to develop vastly improved navigation technology for remote areas. |
| Stellar still births Fri, 22 Aug 2008 00:00:00 EDT |
(University of Bonn) The systematics of celestial bodies apparently needs to be revised. Researchers at the Argelander Institute of Astronomy of the University of Bonn have discovered that brown dwarfs need to be treated as a separate class in addition to stars and planets. To date they had been merely regarded as stars which were below normal size. However, they may well be stellar "miscarriages." |
| GOCE Earth explorer satellite to look at the Earth's surface and core Fri, 22 Aug 2008 00:00:00 EDT |
(European Space Agency) The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earth's gravitational field and to map the reference shape of our planet -- the geoid -- with unprecedented resolution and accuracy. |
| September Geology and GSA Today media highlights Thu, 21 Aug 2008 00:00:00 EDT |
(Geological Society of America) Geology topics reach deep into Earth and far into space -- from magma and plate tectonics to cosmic dust and asteroids -- and touch on the intricate details of our planet, including a 1,200-year record of corals and coral reef health and the wealth of climate change information found in both bat guano and Chinese loess. The GSA Todayarticle studies the end-Permian mass extinction in the marine realm, examining long-term environmental stress and recovery. |

| Drier, warmer springs in US Southwest stem from human-caused changes in winds Tue, 19 Aug 2008 00:00:00 EDT |
(University of Arizona) Human-driven changes in the westerly winds are bringing hotter and drier springs to the American Southwest, according to new research from the University of Arizona in Tucson. Since the 1970s the winter storm track in the western US has been shifting north, particularly in the late winter. As a result, fewer winter storms bring rain and snow to Southern California, Arizona, Nevada, Utah, western Colorado and western New Mexico. |
