You might think that space billions of miles from the sun is a placid, empty domain. In fact, Voyager 2 has been heading outward in the same direction as the solar wind, charged particles streaming from the sun, but things started to get a lot more complicated on August 30, when the spacecraft was 7.8 billion miles from the sun</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.news.com/8301-13580_3-9831906-39.html?tag=newsmap">
There, the spacecraft passed into a new region, where the solar wind suddenly slams into the prevailing breeze and magnetic field left from a series of massive supernovas from 20 million to 30 million years ago</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.news.com/8301-13580_3-9831906-39.html?tag=newsmap">
In this area, called the termination shock, the speed of the solar wind drops abruptly from about 250 miles per second to about 60</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.news.com/8301-13580_3-9831906-39.html?tag=newsmap">"There's something outside pushing in on the field of the heliosphere</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/3B6F4CA2-2675-4C97-84D1-847D5A74EA3B/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
