(PhysOrg.com) -- Last July, people in Spain, Portugal and France watched the brilliant fireball produced by a boulder crashing down through the Earth`s atmosphere. In a paper to be published in the journal Monthly Notices of the Royal Astronomical Society, astronomers Josep M. Trigo-Rodríguez (Institute of Space Sciences, CSIC-IEEC, Spain), José M. Madiedo (University of Huelva-CIECEM, Spain) and Iwan P. Williams (Queen Mary, University of London) present dramatic images of this event. The scientists go on to explain how the boulder may originate from a comet which broke up nearly 90 years ago and suggest the tantalising possibility that chunks of the boulder (and hence pieces of the comet) are waiting to be found on the ground. http://www.physorg.com/news153757491.html Space & Earth Fri, 13 Feb 2009 14:26:07 EST news153757491 Investigation of the fireball that lit up the skies of Alberta and Saskatchewan on November 20 has determined that an asteroid fragment weighing approximately 10 tonnes entered the Earth's atmosphere over the prairie provinces last Thursday evening. And University of Calgary researcher Alan Hildebrand has outlined a region in western Saskatchewan where chunks of the desk-sized space rock are expected to be found. http://www.physorg.com/news146839756.html Space & Earth Tue, 25 Nov 2008 12:49:16 EST news146839756 For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass. http://www.physorg.com/news144091860.html Space & Earth Fri, 24 Oct 2008 18:31:00 EST news144091860
