Defying what a local science professor calls "astronomical odds," what appears to be a pea-sized meteorite was found this summer on the green at the 14th hole at the Aurora Country Club. "The odds of anybody finding something like this around here or anywhere is pretty remote," said Mark Horrell, who has a PhD in geophysical science and teaches astronomy and astrophysics at the Illinois Mathematics and Science Academy. On Wednesday, Horrell examined the extraterrestrial pebble and determined it "has all the hallmarks of a meteorite," but more conclusive tests will need to be conducted. Golf course grounds superintendant John Gurke found the meteorite while doing his normal early morning scouting for turf disease or "anything out of the ordinary" at the course on the southwest side of Aurora. From afar, he noticed a burn mark about five inches in diameter "dead center" of the green. At first, Gurke was peeved because he thought it was a urination stain from a coyote or fox. But as he got closer, he noticed a small hole in the center of the burn spot and dug out the spherical rock and some shrapnel. Gurke ran to his office and googled "meteorite." "It described exactly what I found," he said. Gurke's wife, Julie, who works at Aurora University, asked science professors there what they thought. Eventually, they referred the Gurkes to Horrell at IMSA, a residential high school in Aurora for some of the most gifted science students in the state. Horrell and Bob Brazzle, a physics teacher at IMSA, were star-struck when they realized the rock actually could be a meteorite. "A lot of people think they found one but it's actually a piece of limestone or something," Horrell said. "There's nothing I've ever seen like this." He said only about one in 1,000 suspected meteorites actually turn out to be meteorites. And Gurke's is on it's way to being one of them. The rock reacted to a magnet, meaning it has the high content of iron found in meteorites, and it came with a charred-looking outer crust showing that it cooled and recrystallized after being heated in the atmosphere, Brazzle said. The pea-sized pebble was made even smaller Wednesday, when it was cracked during testing. Horrell said its texture and dark lavender and metallic color is not like anything you'd expect to find naturally occurring in the Midwest. Both scientists said it's very rare to find a meteorite that small because they typically become camouflaged in the ground. "If it hadn't been on the green he probably wouldn't have found it," Horrell said. He said most meteorites found are the size of a softball. Brazzle said it was possible more meteorites could be found in the area because meteorites don't typically fly solo. IMSA professors and students, and possibly professionals at the University of Illinois at Chicago, will do further testing on the meteorite. If it is in fact a meteorite, Brazzle said, it would likely be named "Aurora" after the place it was found. But since there might already be a meteorite with that name, "maybe they'll call it Aurora Country Club," Horrell joked. Received on Thu 14 Sep 2006 01:22:21 PM PDT |
