At the end of its life cycle, a star begins to collapse in the middle and throws new material into space. The new material eventually becomes incorporated into new planets and life. Now, a University of Missouri professor identified new features in the material that is being ejected from the dying star Helix Nebula. http://www.physorg.com/news167317412.html Space & Earth Mon, 20 Jul 2009 14:50:08 EST news167317412 A wind storm that ripped across western China's Taklimakan desert kicked up hundreds of thousands of tonnes of dust that high-altitude winds then carried around the world in less than two weeks, a study says. http://www.physorg.com/news167315325.html Space & Earth Mon, 20 Jul 2009 14:00:02 EST news167315325 (PhysOrg.com) -- Scientists have combined a trio of shots taken seconds apart through different colored filters to create a special-effects portrait of a moving dust devil on Mars. http://www.physorg.com/news166807575.html Space & Earth Tue, 14 Jul 2009 17:00:03 EST news166807575 This new guide for astronomers, known as the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) shows the Milky Way in submillimetre-wavelength light (between infrared light and radio waves). Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. http://www.physorg.com/news165669952.html Space & Earth Wed, 01 Jul 2009 12:27:58 EST news165669952 US and European scientists were Tuesday bidding farewell to the tenacious solar probe Ulysses which has been recording data around the sun for more than 18 years, four times longer than planned. http://www.physorg.com/news165584644.html Space & Earth Tue, 30 Jun 2009 13:10:01 EST news165584644 (PhysOrg.com) -- Accelerated snowmelt--precipitated by desert dust blowing into the mountains--changes how alpine plants respond to seasonal climate cues that regulate their life cycles, according to results of a new study reported this week in the journal Proceedings of the National Academy of Sciences (PNAS). These results indicate that global warming may have a greater influence on plants' annual growth cycles than previously thought. http://www.physorg.com/news165516077.html Space & Earth Mon, 29 Jun 2009 18:20:03 EST news165516077 For the first time, direct evidence of lightning has been detected on Mars, say University of Michigan researchers who found signs of electrical discharges during dust storms on the Red Planet. http://www.physorg.com/news164468762.html Space & Earth Wed, 17 Jun 2009 14:46:51 EST news164468762 (PhysOrg.com) -- Using NASA's Spitzer Space Telescope, an international team of astronomers has discovered streams of young stars flowing from their natal cocoons in distant galaxies. These distant rivers of stars provide an answer to one of astronomy's most fundamental puzzles: how do young stars that form clustered together in dense clouds of dust and gas disperse to form the large, smooth distribution seen in the disks of spiral galaxies like the Milky Way? http://www.physorg.com/news160410037.html Space & Earth Fri, 01 May 2009 15:20:59 EST news160410037 A popular television commercial from the 1970s shows a Native American man in buckskin and feathers paddling his canoe through ink-black waters, past refineries billowing smoke. He comes aground on a litter-strewn shoreline and finds a freeway clogged with cars and exhaust fumes. Someone chucks fast-food garbage out a car window and it splatters onto his moccasins. The camera zooms in on a single tear streaming down his cheek, while the voiceover tells us "People start pollution. People can stop it." http://www.physorg.com/news160328375.html Medicine & Health Thu, 30 Apr 2009 16:41:15 EST news160328375 (PhysOrg.com) -- Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. Their new data provides evidence that this remnant is from a type Ia supernova - the explosion of a white dwarf star - and raises questions about the ways in which magnetic fields affect the generation of the remnant's cosmic ray particles. http://www.physorg.com/news159639776.html Space & Earth Wed, 22 Apr 2009 17:23:25 EST news159639776 (PhysOrg.com) -- Scientists at Arizona State University's Mars Space Flight Facility are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a new dust storm that has erupted on the Red Planet. http://www.physorg.com/news159470509.html Space & Earth Mon, 20 Apr 2009 18:22:14 EST news159470509 (PhysOrg.com) -- Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, the IRAM Millimetre-wave Telescope in Spain, and the Spitzer Space Telescope in orbit above the Earth, have completed the most wide-ranging census ever produced of dynamical star formation in and around the well-known Great Nebula of Orion. http://www.physorg.com/news159460527.html Space & Earth Mon, 20 Apr 2009 15:35:59 EST news159460527 (PhysOrg.com) -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water. This could alter the pattern of both rain and snow in a warmer world. http://www.physorg.com/news159370515.html Space & Earth Sun, 19 Apr 2009 14:35:46 EST news159370515 In the 1960s and 1970s, the Apollo Moon Program struggled with a minuscule, yet formidable enemy: sticky lunar dust. Four decades later, a new study reveals that forces compelling lunar dust to cling to surfaces -- ruining scientific experiments and endangering astronauts' health -- change during the lunar day with the elevation of the sun. http://www.physorg.com/news159201494.html Space & Earth Fri, 17 Apr 2009 15:38:51 EST news159201494 (PhysOrg.com) -- Space seems exotic, forbidding, and remote, but imagine trying to survive winter without a heated shelter or warm clothing. Our ancestors developed these technologies because they needed room to grow; without them, we would still be confined to narrow areas along the equator, but with them, we could live anywhere in the world. With the right technology, space is just another place for people to live. http://www.physorg.com/news159195930.html Space & Earth Fri, 17 Apr 2009 14:06:14 EST news159195930 (PhysOrg.com) -- Heading into a period of the Martian year prone to major dust storms, the team operating NASA's twin Mars rovers is taking advantage of eye-in-the-sky weather reports. http://www.physorg.com/news159122161.html Space & Earth Thu, 16 Apr 2009 17:36:47 EST news159122161 (PhysOrg.com) -- Engineers have successfully ejected the dust cover from NASA's Kepler telescope, a spaceborne mission soon to begin searching for worlds like Earth. http://www.physorg.com/news158427654.html Space & Earth Wed, 08 Apr 2009 16:41:43 EST news158427654 Astronomy & Astrophysics is publishing the first clear detection of signatures long sought in the spectra of X-ray astronomical sources.
