A dazzling fireball streaks across the Siberian sky. Minutes later an immense blast topples 80 million trees and knocks people off their feet 60 kilometers away: It's the violent end of an alien dogfight, with one spaceship destroyed in mid-air and the other turning and vanishing into space. The enigma has fascinated scientists for more than a century. Another fire in the sky may finally lift the veil. Earlier this year, thousands of people in the Chelyabinsk region of Russia watched as a large fireball shot across the morning sky before exploding.
