sans-serif">NASA's Voyager 2
spacecraft has followed its twin Voyager 1 into
the solar system's final frontier, a vast region
at the edge of our solar system where the solar
wind runs up against the thin gas between the
stars.</FONT>

different path, entering this region, called the
heliosheath, on August 30, 2007.  Because Voyager
2 crossed the heliosheath boundary, called the
solar wind termination shock, about 10 billion
miles away from Voyager 1 and almost a billion
miles closer to the sun, it confirmed that our
solar system is "
squashed" or "
dented"- that the bubble carved into interstellar
space by the solar wind is not perfectly round.
Where Voyager 2 made its crossing, the bubble is
pushed in closer to the sun by the local
interstellar magnetic field.</FONT></P></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://voyager.jpl.nasa.gov/"><TABLE width="124" cellspacing="0" cellpadding="0" border="0"><TBODY><TR><TD valign="top" colspan="3"><IMG width="124" height="20" alt="Golden Record" src="http://voyager.jpl.nasa.gov/images/rtcol_goldenrecvv.gif" /></TD></TR><TR valign="top"><TD background="images/rtcol_bg.gif" colspan="3"> <DIV align="center"><A href="http://voyager.jpl.nasa.gov/spacecraft/goldenrec.html">
