EzInKy writes: The BBC reports: A meteor crashing in central Russia's Ural mountains has injured at least 500 people, as the shockwave blew out windows and rocked buildings. Scientists have played down suggestions that there is any link between the event in the Urals and 2012 DA14, an asteroid expected to race past the Earth on Friday at a distance of just 27,700km (17,200 miles) — the closest ever predicted for an object of that size. Prof Alan Fitzsimmons, of the Astrophysics Research Centre at Queen's University Belfast, said there was "almost definitely" no connection. "One reason is that 2012 DA14 is approaching Earth from the south, and this object hit in the northern hemisphere," he told BBC News. "This is literally a cosmic coincidence, although a spectacular one."
