Now there's a new short movie that shows what the MIRI detectors are all about and what they can do. http://www.physorg.com/news181320671.html Space & Earth Tue, 29 Dec 2009 15:10:05 EST news181320671 (PhysOrg.com) -- In more than 30 locations around the world, the phenomenon of singing sand dunes has intrigued explorers, tourists, and scientists. When an avalanche occurs or even when the sand is pushed by hand, it emits a powerful, monotonous sound that can last up to several minutes and be heard more than a mile away. Sometimes observers mistake the noise for a loud, low-flying aircraft. Although scientists have spent many years investigating the sound, the cause remains a mystery. Studies have suggested that the singing dunes phenomenon is a completely new way of generating sound. http://www.physorg.com/news180086325.html Physics Tue, 15 Dec 2009 09:30:01 EST news180086325 (PhysOrg.com) -- Hawaii may be paradise for vacationers, but for geologists it has long been a puzzle. Plate tectonic theory readily explains the existence of volcanoes at boundaries where plates split apart or collide, but mid-plate volcanoes such as those that built the Hawaiian island chain have been harder to fit into the theory. A classic explanation, proposed nearly 40 years ago, has been that magma is supplied to the volcanoes from upwellings of hot rock, called mantle "plumes," that originate deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. http://www.physorg.com/news179074389.html Space & Earth Thu, 03 Dec 2009 14:53:40 EST news179074389 Noted for harbouring Eta Carinae -- one of the wildest and most massive stars in our galaxy -- the impressive Carina Nebula also houses a handful of massive clusters of young stars. The youngest of these stellar families is the Trumpler 14 star cluster, which is less than one million years old -- a blink of an eye in the Universe's history. This large open cluster is located some 8000 light-years away towards the constellation of Carina (the Keel). http://www.physorg.com/news179068963.html Space & Earth Thu, 03 Dec 2009 13:23:15 EST news179068963 (PhysOrg.com) -- iPhones are being used as musical instruments in a new course at the University of Michigan. http://www.physorg.com/news178915531.html Technology Tue, 01 Dec 2009 18:46:06 EST news178915531 NASA's Wide-field Infrared Survey Explorer has been wrapped in the outer nose cone, or "fairing," that will protect it during its scheduled Dec. 9 launch from Vandenberg Air Force Base, Calif. http://www.physorg.com/news178912011.html Space & Earth Tue, 01 Dec 2009 18:30:01 EST news178912011 (PhysOrg.com) -- Engineers are busy cooling the science instrument on NASA's Wide-field Infrared Survey Explorer, or WISE.

Etched into boron carbide, a super-hard substance used in accelerator shielding and body armor, the lettering has helped researchers at SLAC National Accelerator Laboratory explore the capabilities of the world's first hard X-ray laser, the Linac Coherent Light Source. http://www.physorg.com/news175283137.html Physics Tue, 20 Oct 2009 19:10:03 EST news175283137 (PhysOrg.com) -- It takes a lot of energy to strip all ten electrons from an atom of neon. Doing it from the inside out, knocking away the most-closely-held, innermost electrons first, is an even rarer feat. But the brilliant X-ray pulses of the Linac Coherent Light Source have done just that, in the successful first test of the unprecedented X-ray laser with its first scientific instrument. The result demonstrates the machine's unique capabilities -with the world's brightest and shortest X-ray laser pulses -and marks the first of two milestones in readiness for the launch of LCLS scientific user experiments this October. http://www.physorg.com/news172503425.html Physics Fri, 18 Sep 2009 15:00:04 EST news172503425 Wind speeds and directions were measured for the first time in the Mars polar region using the Phoenix lander`s Telltale instrument. Astronomers recorded Easterly winds of approximately 15-20 kilometres per hour during the martian mid-summer. When autumn approached, the winds increased and switched round to come predominantly from the West. While these winds appeared to be dominated by turbulence, the highest wind speeds recorded of up to nearly 60 kilometres per hour coincided with the passing of weather systems, when also the number of dust devils increased by an order of magnitude. The results are being today at the European Planetary Science Congress in Potsdam by Dr Haraldur Gunnlaugsson. http://www.physorg.com/news172305133.html Space & Earth Wed, 16 Sep 2009 07:32:51 EST news172305133 (PhysOrg.com) -- It's every violinmaker's dream to produce an instrument to rival the sound of a Stradivarius but now researchers at The University of Nottingham are trying to do just that… using acoustic physics and carbon fibre engineering. http://www.physorg.com/news171897397.html Chemistry Fri, 11 Sep 2009 14:17:57 EST news171897397 (AP) -- Danaher Corp. said Wednesday it will shed about twice as many existing jobs and plants as previously announced and also buy a global provider of medical instruments to analyze molecules. http://www.physorg.com/news171121852.html Technology Wed, 02 Sep 2009 14:51:16 EST news171121852 Salpinx, barbiton, aulos, syrinx.

Like the Orion Nebula Cluster, RCW 38 is an "embedded cluster", in that the nascent cloud of dust and gas still envelops its stars. Astronomers have determined that most stars, including the low mass, reddish ones that outnumber all others in the Universe, originate in these matter-rich locations. Accordingly, embedded clusters provide scientists with a living laboratory in which to explore the mechanisms of star and planetary formation. http://www.physorg.com/news169894333.html Space & Earth Wed, 19 Aug 2009 09:52:41 EST news169894333 GOES-14, formerly GOES-O, has achieved another significant milestone with the release of the first formal Solar Image from the Solar X-Ray Imager (SXI). http://www.physorg.com/news169819906.html Space & Earth Tue, 18 Aug 2009 13:50:01 EST news169819906 (PhysOrg.com) -- The new image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the exotic class of B[e] stars [1].
