Every 11 years, the sun undergoes a furious upheaval. Dark sunspots burst forth from beneath the sun's surface. Explosions as powerful as a billion atomic bombs spark intense flares of high-energy radiation. Clouds of gas big enough to swallow planets break away from the sun and billow into space. It's a flamboyant display of stellar power. http://www.physorg.com/news175970429.html Space & Earth Wed, 28 Oct 2009 17:41:06 EST news175970429 Every 11 years, the sun undergoes a furious upheaval.

Now, for the first time, solar physicists might understand why. http://www.physorg.com/news164550243.html Space & Earth Thu, 18 Jun 2009 14:00:01 EST news164550243 (PhysOrg.com) -- University of Delaware researchers in Sweden have launched a giant balloon taller than a football field that is now flying at the edge of space to collect data on cosmic rays -- the most super-charged particles in the universe. http://www.physorg.com/news162143391.html Space & Earth Thu, 21 May 2009 19:35:59 EST news162143391 With the U.S. Congress beginning to consider regulations on greenhouse gases, a troubling hypothesis about how the sun may impact global warming is finally laid to rest. http://www.physorg.com/news161268877.html Space & Earth Mon, 11 May 2009 13:54:56 EST news161268877 (PhysOrg.com) -- Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes affect orbiting satellites, including the GPS system. http://www.physorg.com/news160223027.html Space & Earth Wed, 29 Apr 2009 11:24:20 EST news160223027 (PhysOrg.com) -- During the Maunder Minimum, a period of diminished solar activity between 1645 and 1715, sunspots were rare on the face of the sun, sometimes disappearing entirely for months to years. At the same time, Earth experienced a bitter cold period known as the "Little Ice Age." http://www.physorg.com/news157041575.html Space & Earth Mon, 23 Mar 2009 15:40:49 EST news157041575 Global warming is mainly caused by greenhouse gas emissions resulting from human activities; however, current climatic variations may be affected `around 15% or 20%` by solar activity, according to the researcher Manuel Vázquez from the Canary Islands` Astrophysics Institute (IAC) at the Sun and Climate Change conference, organised as part of the El Escorial summer courses by Madrid's Complutense University. http://www.physorg.com/news135581249.html Space & Earth Fri, 18 Jul 2008 06:27:29 EST news135581249
