Background: NASA artist captures an asteroid at the moment of impact. The front is beginning to vaporize while the top does not yet feel the impact. Traveling at 25 km/second, this asteroid is moving too fast to capture with a camera. A distant viewer would see only a flash of painfully bright light.
