Amateur sleuth uses viral videos to trace the origins of Russian meteor
An investigation by an amateur sleuth using “Google Earth, YouTube and high-school math,” has led to a scientific study hunting down the origins of the meteor which hit Russia earlier this month.

Stefan Geens wrote on his blog Ogle Earth that he was inspired to look into the Russian meteor when he started seeing viral videos of it on the Internet.

“Might it be possible to use this viral footage with Google Earth to have an initial go at mapping the meteorite’s trajectory?” he pondered. (Ogle Earth Blog / Youtube; AFP PHOTO / URAL FEDERAL UNIVERSITY/ALEXANDER KHLOPOTOV)
