Never-before-seen crystals were found in meteorite dust. Massive space rock burst above Chelyabinsk, Russia, nine years ago.
Fortunately, the meteor burst 14.5 miles above Chelyabinsk, Russia, showering the region in small fragments and escaping a cataclysmic crash with the earth.
Experts said the occurrence was a wake-up call about the hazards of asteroids.
Chelyabinsk was the greatest meteor explosion since 1908's Tunguska.
In a recent study, researchers investigated meteorite dust left behind after a meteor exploded. As meteors fire, they generate a little quantity of dust, but scientists can't discover it
NASA reports that after the Chelyabinsk meteor burst, a large cloud of dust remained in the sky for four days before falling to Earth.
