The Voyager spacecraft are now in the outermost layer of the heliosphere, traveling toward interstellar space - the first man-made spacecraft to travel such a vast distance from Earth. http://www.physorg.com/news177092513.html Space & Earth Tue, 10 Nov 2009 16:40:01 EST news177092513 (PhysOrg.com) -- At the edge of our solar system in December 2004, the Voyager 1 spacecraft encountered something never before experienced during its then 26-year cruise through the solar system - an invisible shock formed as the solar wind piles up against the gas in interstellar space. This boundary, called the termination shock, marks the beginning of our solar system's final frontier, a vast expanse of turbulent gas and twisting magnetic fields. http://www.physorg.com/news136215335.html Space & Earth Fri, 25 Jul 2008 14:35:35 EST news136215335 NASA's sun-focused STEREO spacecraft unexpectedly detected particles from the edge of the solar system last year, allowing University of California, Berkeley, scientists to map for the first time the energized particles in the region where the hot solar wind slams into the cold interstellar medium. http://www.physorg.com/news134223453.html Space & Earth Wed, 02 Jul 2008 13:17:33 EST news134223453
