So researchers  interested in understanding the still somewhat mysterious inner  workings of our planet&#8217;s iron-rich core must obtain their information  indirectly, for example, by measuring seismic waves traveling through  the earth&#8217;s interior. But by replicating the intense pressures and  temperatures found at the core in a lab, physicists Jeffrey H. Nguyen  and Neil C. Holmes have now shed some light on how iron behaves deep  inside the earth. In the January 22 <em>Nature,<\/em> the Lawrence Livermore  National Laboratory researchers report subjecting a sample of iron to  shockwaves generated by a gas gun, which creates pressures millions of  times the pressure of air at the earth&#8217;s surface. From their  experiments, the researchers discovered that iron at earth-core  conditions melts at a temperature of about 8,720 degrees Fahrenheit. &#8220;By  determining the melting point of iron, we can estimate the temperature  at the core boundaries,&#8221; Nguyen stated in a press release. &#8220;This  information provides us with another tool to study the temperature of  the Earth&#8217;s core.&#8221; <\/span><\/p>\n<h6><em>This news brief appeared in the Discoveries column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 1\/27\/2004.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Unless you&#8217;re a character in a Jules Verne novel, journeying to the center of the earth remains impossible.
