On Earth, we tend to find dust nothing more than a nuisance that blankets our furniture and causes us to sneeze. Cosmic dust can also be a hindrance to astronomers because cameras using visible light cannot see through it. However, studying cosmic dust in detail helps astronomers to pin down the ingredients of the raw mixture that eventually gives birth to stars. http://www.physorg.com/news178899301.html Space & Earth Tue, 01 Dec 2009 14:16:51 EST news178899301 (PhysOrg.com) -- Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be `building` their own host galaxy. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars. http://www.physorg.com/news178804126.html Space & Earth Mon, 30 Nov 2009 11:49:22 EST news178804126 A proposed space mission that aims to measure dark energy could also detect planets that current surveys are unable to find. http://www.physorg.com/news177874211.html Space & Earth Thu, 19 Nov 2009 18:00:05 EST news177874211 (PhysOrg.com) -- Just as many people are surprised to find themselves packing on unexplained weight around the middle, astronomers find the evolution of bulges in the centres of spiral galaxies puzzling. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that astronomers have conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies. http://www.physorg.com/news177764242.html Space & Earth Wed, 18 Nov 2009 10:58:27 EST news177764242 (PhysOrg.com) -- Rosetta's OSIRIS imaging system spotted an anticyclone over the South Pacific on the morning of 13 November. The images show the scene roughly as a human eye would see it. http://www.physorg.com/news177670463.html Space & Earth Tue, 17 Nov 2009 08:55:19 EST news177670463 (PhysOrg.com) -- Images and data taken just before closest approach were downloaded this morning, and they show the lights of North America in the night and a glowing Southern Hemisphere. http://www.physorg.com/news177345195.html Space & Earth Fri, 13 Nov 2009 14:50:01 EST news177345195 (PhysOrg.com) -- This morning, mission controllers confirmed that ESA`s comet chaser Rosetta had swung by Earth at 8:45 CET as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. http://www.physorg.com/news177313479.html Space & Earth Fri, 13 Nov 2009 05:48:20 EST news177313479 (PhysOrg.com) -- This spectacular image of our home planet was captured by the OSIRIS instrument on ESA's Rosetta comet chaser earlier today as the spacecraft approached Earth for the third and final swingby. Closest approach is due at 08:45 CET, 13 November 2009. http://www.physorg.com/news177262843.html Space & Earth Thu, 12 Nov 2009 15:50:01 EST news177262843 When Europe's comet chaser Rosetta swings by Earth tomorrow for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades. http://www.physorg.com/news177245318.html Space & Earth Thu, 12 Nov 2009 10:49:40 EST news177245318 (PhysOrg.com) -- Into its second week in orbit, Proba-2's spacecraft platform has proven to be in excellent health. This leaves the way clear for commissioning the many new technology payloads aboard the mini-satellite, among the smallest ever flown by ESA. http://www.physorg.com/news177179866.html Space & Earth Wed, 11 Nov 2009 16:50:01 EST news177179866 Medications frequently given to cancer patients to reduce their risk of anemia are associated with an increased risk of deep vein thrombosis or pulmonary embolism, according to new research led by Dawn Hershman, M.D, M.S., co-director of the breast cancer program at the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian Hospital/Columbia University Medical Center. The findings will be published online on Nov. 10, 2009 in the Journal of the National Cancer Institute (ahead of the Dec. 2, 2009 print edition). http://www.physorg.com/news177097215.html Medicine & Health Tue, 10 Nov 2009 17:50:01 EST news177097215 (PhysOrg.com) -- A never-before-seen view of the turbulent heart of our Milky Way galaxy is being unveiled by NASA on Nov. 10. This event will commemorate the 400 years since Galileo first turned his telescope to the heavens in 1609. http://www.physorg.com/news177092798.html Space & Earth Tue, 10 Nov 2009 16:50:02 EST news177092798 Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. http://www.physorg.com/news177080138.html Space & Earth Tue, 10 Nov 2009 12:56:02 EST news177080138 (PhysOrg.com) -- After the trajectory correction manoeuvre on 22 October, Rosetta has lined up on a near-perfect Earth approach path. The manoeuvre was so precise that mission controllers decided not to use the additional manoeuvre slot that was available yesterday. http://www.physorg.com/news176736191.html Space & Earth Fri, 06 Nov 2009 14:10:04 EST news176736191 (PhysOrg.com) -- Hylas, a flexible, broadband Ka-band satellite, is steadily moving towards completion. The communications payload has been shipped from England to India for integration with the platform, marking a key milestone for the project. http://www.physorg.com/news176736080.html Space & Earth Fri, 06 Nov 2009 13:50:01 EST news176736080
