Today, two cosmic visitors made the news around the globe today, February 15, 2013. First, this morning an unexpected visitor blazed through the mid-morning sky of Russia near the city of Chelyabinsk. It produced a spectacular fireball accompanied by a shockwave that resulted in a sonic boom. The shockwave made windows shatter which resulted in injuries to hundreds of people. It is very unusual that meteorite falls cause injuries. To date there is no documented case of a human casualty caused by a meteorite although some injuries have been reported from previous falls.
