Now, a portion of the hundreds of fragments from the 10-tonne Buzzard Coulee meteorite that lit up the skies above Alberta and Saskatchewan last fall are being returned to the landowners who lent them for scientific research. Some of the fragments will remain at a University of Calgary lab, while others will be returned over the weekend to three landowners who'd found the chunks on their land, said U of C planetary scientist Alan Hildebrand. "We'll keep some of them as part of our research collection and various sorts of research will be done on them," he said. Already, scientists have gleaned new knowledge in several areas, including the size of the meteorite that entered the atmosphere and the length of time since it blasted off the parent asteroid, said Hildebrand. The asteroid produced a huge fireball visible over prairie skies when it hurtled through the atmosphere on Nov. 20, 2008. It landed in an area of southwestern Saskatchewan. Searchers and landowners found as many as 700 fragments that were taken to the U of C for research. Since then, researchers have been closely studying the specimens, "pairing" the fragments where possible. Fitting two adjacent pieces together provides clues about how the pieces broke up in the atmosphere, Hildebrand said. "For us the exciting thing right now is just finding these pairs. We've found several in the last couple days," Hildebrand said. "That's the fun thing right now." jkomarnicki at theherald.canwest.com Received on Sat 25 Jul 2009 07:43:16 PM PDT |
