Asteroid Detection
It is widely believed that a large asteroid collision was responsible for the event that caused dinosaurs to suddenly go extinct after ruling the planet for millions of years. They were not capable of foreseeing the event, but humans are. So we spend time, effort, and money scanning the sky for these dangerous objects.
Even so, recently an asteroid exploded in an air-burst above the city of Chelyabinsk, Russia. The asteroid wasn't detected until it slammed into the atmosphere at a speed of tens of kilometers/second.
I recently watched this fascinating video about the tremendous difficulty of detecting earth-crossing asteroids, and thought I'd share it.
