			The shock wave is a natural phenomenon found above the Earth's surface, on the side facing the <A class="iAs" classname="iAs" href="#" target="_blank" itxtdid="4770477">Sun</A>, at 96,100 kilometers (59,700 miles), at around a quarter of the distance to the Moon and it's produced by the flow of electrically charged particles from the Sun entering Earth's magnetic field</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://news.softpedia.com/news/Shocking-Discovery-Above-the-Earth-039-s-Surface-54658.shtml">
As the particles collide with the magnetic field, they're rapidly slowed, causing a barrier of electrified gas, called the bow shock, to build up, much like water is pushed to the sides by the nose of a boat.</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://news.softpedia.com/news/Shocking-Discovery-Above-the-Earth-039-s-Surface-54658.shtml">
The reforming of this wave was theorized 20 years ago, but it's the first time it was recorded. The recording was made as the four spacecraft, traveling at 600 kilometers from each other, approached the bow shock.</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://news.softpedia.com/news/Shocking-Discovery-Above-the-Earth-039-s-Surface-54658.shtml">
As bow shocks around faraway celestial bodies are linked to some of the most energetic events in the Universe, the reports of their reforming has significant implications for future investigations.</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/FCAF7CBF-4CB7-4155-A507-3B177CD5465E/blog/" title="blog or email this clip"><img src="http://content8.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>
