<H1>A giant breach in Earth's magnetic field</H1>
<P><FONT face=Verdana>NASA's five <STRONG>THEMIS</STRONG> spacecraft have
discovered a breach in Earth's magnetic field ten times larger than anything
previously thought to exist.</FONT></P>
<P><FONT face=Verdana>Solar wind can flow in through the opening to "load up"
the magnetosphere for powerful geomagnetic storms. But the breach itself is not
the biggest surprise. Researchers are even more amazed at the strange and
unexpected way it forms, overturning long-held ideas of space
physics.</FONT></P>
