Stars  rich in iron, nickel, and other metallic elements are more likely to  have planets, reported Debra Fischer of the University of California at  Berkeley and her colleagues at the International Astronomical Union  meeting in Sydney last week. The astronomers compared 754 stars, some  with planets, most without, and proved a correlation between the amount  of metal in a star and whether or not it formed planets. More metal  means more raw material to build planets. &#8220;These results tell us why  some of the stars in our Milky Way galaxy have planets while others do  not. The heavy metals must clump together to form rocks, which  themselves clump into the solid cores of planets,&#8221; said Geoffrey Marcy, a  professor of astronomy at UC Berkeley.  Added Fischer, &#8220;If you look at  the metal-rich stars, 20 percent have planets. That&#8217;s stunning.&#8221; <\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 7\/29\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Last year, it seemed as if the entire planet revolved around Ozzy Osbourne, and now there&#8217;s a scientific explanation (if the Oz were a gargantuan exploding ball of hydrogen, that is).
