Canadian astronomers on hunt for meteorMarch 10, 2008Astronomers from The University of Western Ontario in London, Ontario, have captured rare video of a meteor falling to Earth. The Physics and Astronomy Department at Western has a network of all-sky cameras in Southern Ontario that scan the sky monitoring for meteors. Associate Professor Peter Brown, who specializes in the study of meteors and meteorites, says that Wednesday evening (March 5) at 10:59 p.m. EST these cameras captured video of a large fireball and the department has also received a number of calls and emails from people who actually saw the light. Brown along with Wayne Edwards, a post doctorate student, hope to enlist the help of local residents in recovering one or more possible meteorites that may have crashed in the Parry Sound area.
"Most meteoroids burn up by the time they hit an altitude of 60 or 70 kilometres from Earth," says Edwards. "We tracked this one to an altitude of about 24 kilometres so we are pretty sure there are at least one, and possibly many meteorites, that made it to the ground." Edwards says the lab can narrow the ground location where the meteorite would have fallen, to about 12 square kilometres and have created a map that may assist in locating the meteorite. The rock, or rocks, would probably weigh a kilogram or slightly more. "We would love to find a recovered meteorite on this one, because we have the video and we have the data and by putting that together with the meteorite, there is a lot to be learned."

All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth. Insect attack may have finished off dinosaurs Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new book argues that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force - biting, disease-carrying insects. Freshly painted Arecibo Observatory returns to work, spies object associated with meteor showers After receiving its first fresh, full coat of paint in more than 40 years, Arecibo Observatory made its first observation in more than six months at 6:36 a.m., Saturday, Dec. 8. Dinosaur Deaths Outsourced to India? A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. Meteor no longer prime suspect in great extinction The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory. Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. More than a meteor likely killed dinosaurs 65 million years ago Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period. New theory for mass extinctions A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. Far more than a meteor killed dinos There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, according to a paleontologist who says multiple meteor impacts, massive volcanism in India, and climate changes culminated in the end of the Cretaceous Period. Metal deformation studies lead to new understanding of materials at extreme conditions By combining very large-scale molecular dynamics simulations with time-resolved data from laser experiments of shock wave propagation through specific metals, scientists at the Lawrence Livermore National Laboratory are now able to better understand the evolution of high-strain-rate plasticity.
