| UV exposure has increased over the last 30 years, but stabilized since the mid-1990s Tue, 16 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) NASA scientists analyzing 30 years of satellite data have found that the amount of ultraviolet radiation reaching Earth's surface has increased markedly over the last three decades. Most of the increase has occurred in the mid-and-high latitudes, and there's been little or no increase in tropical regions. |
| A NASA satellite mosaic of twin tropical troublesome cyclones: Tomas and Ului Tue, 16 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) Tropical Cyclones Tomas and Ului are both causing problems for residents in the South Pacific Ocean today, March 16, and watches and warnings are in effect for the Fiji Islands and the Solomon Islands, respectively. NASA's Aqua and Terra satellites passed over each storm and their images were combined to show the close proximity of the troublemaking twins. |
| News from Stardust Tue, 16 Mar 2010 00:00:00 EDT |
(Goethe University Frankfurt) As reported last week in Houston, two most promising candidates for stardust have been identified. They were collected during NASA's Stardust mission. Since 2006 scientists are scanning samples for the needle in the haystack: dust particles from others parts of our galaxy that were carried to our solar system via the interstellar stream. Geoscientists of Frankfurt's Goethe-University helped to identify the chemical structure of the particles. |
| Jupiter's spot seen glowing Tue, 16 Mar 2010 00:00:00 EDT |
(ESO) New ground-breaking thermal images obtained with ESO's Very Large Telescope and other powerful ground-based telescopes show swirls of warmer air and cooler regions never seen before within Jupiter's Great Red Spot, enabling scientists to make the first detailed interior weather map of the giant storm system linking its temperature, winds, pressure and composition with its color. |
| Simulations solve a 20-year-old riddle about why nebulae around masssive stars don't disappear Tue, 16 Mar 2010 00:00:00 EDT |
(American Museum of Natural History) New simulations show that as the gas cloud surrounding a massive star collapses, it forms dense filamentary structures that absorb the star's radiation when it passes through them. This makes heated nebulae flicker like a candle flame. |
| X-ray telescope to detect dark energy in space Tue, 16 Mar 2010 00:00:00 EDT |
(Physikalisch-Technische Bundesanstalt (PTB)) It will be on board in 2012, when a Soyus-2 rocket carries an X-ray telescope into space to decode the nature of the universe's dark energy: an X-ray detector developed by the Max Planck Institute for Extraterrestrial Physics. Its challenging task is to detect the weak X-rays from celestial bodies, without being disturbed by the visible and UV light from billions of stars. |
| Photos feature images of eyes, Hubble Telescope combined Mon, 15 Mar 2010 00:00:00 EDT |
(University of Houston) Photographer Keith Carter will deliver a lecture March 24 in honor of receiving the 2010 "Lenses of Our Perception" Award from the UH Visual Studies program. He developed a layered vision combining Hubble Space Telescope photographs with inward images of his own eye, following diagnosis and treatment of ocular melanoma, to create colorful vistas of perception. He relies on both telescopic and microscopic technologies. |
| Solomon Islands under warnings for Category 4 Cyclone Ului Mon, 15 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) There are two powerful cyclones in the Southern Pacific Ocean this week, Tomas and Ului. Ului is a Category 4 Cyclone on the Saffir-Simpson Scale and is affecting the Solomon Islands where warnings and watches have been posted today, March 15. NASA satellite data has confirmed that Ului is a strong cyclone with a wide reach. |
| Powerful Cyclone Tomas battering Northern Fiji islands Mon, 15 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) Tomas grew into a monster Category 4 cyclone and thrashed the northern Fiji Islands with heavy rains and maximum sustained winds of up to 170 mph (275 kph). The Moderate Resolution Imaging Spectroradiometer instrument on NASA's Aqua satellite captured a visible image of most of Cyclone Tomas on Mar. 14 10:21 p.m. ET and noticed the storm's eye is cloud-filled. |
| New lunar images and data available to the public Mon, 15 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) The public can follow along with NASA on its journey of lunar discovery. On March 15, the publicly accessible Planetary Data System will release data sets from the seven instruments on board NASA's Lunar Reconnaissance Orbiter. |
| Stellar McGill researcher receives Killam research fellowship Mon, 15 Mar 2010 00:00:00 EDT |
(McGill University) McGill University is pleased to announce that the Canada Council for the Arts has awarded a Killam Research Fellowship to Dr. Victoria Kaspi for her astrophysics research. |
| JHU astrophysicist and team win $5 million stimulus grant to build telescope Mon, 15 Mar 2010 00:00:00 EDT |
(Johns Hopkins University) A Johns Hopkins team has won a $5 million NSF grant to probe what happened during the universe's first trillionth of a second, when it suddenly grew from submicroscopic to astronomical size in far less than time than it takes to blink your eye. |
| Super supernova: White dwarf star system exceeds mass limit Mon, 15 Mar 2010 00:00:00 EDT |
(Yale University) An international team led by Yale University has, for the first time, measured the mass of a type of supernova thought to belong to a unique subclass and confirmed that it surpasses what was believed to be an upper mass limit. Their findings could affect the way cosmologists measure the expansion of the universe. |
| New Hubble treasury project to survey first third of cosmic time Mon, 15 Mar 2010 00:00:00 EDT |
(University of California - Santa Cruz) Astronomers will peer deep into the universe in five directions to document the early history of star formation and galaxy evolution in an ambitious new project requiring an unprecedented amount of time on the Hubble Space Telescope. |
| Seeking dark matter on a desktop Mon, 15 Mar 2010 00:00:00 EDT |
(DOE/SLAC National Accelerator Laboratory) Desktop experiments could point the way to dark matter discovery, complementing grand astronomical searches and deep underground observations. According to recent theoretical results, small blocks of matter on a tabletop could reveal elusive properties of the as-yet-unidentified dark matter particles that make up a quarter of the universe. This finding was announced today by theorists from the Stanford Institute for Materials and Energy Science, a joint institute of SLAC National Accelerator Laboratory and Stanford University. |
