Original Caption: This movie taken by Deep Impact's flyby spacecraft shows the flash that occurred when comet Tempel 1 ran over the spacecraft's probe. It was taken by the flyby craft's high-resolution camera over a period of about 40 seconds. The image has been digitally processed to enhance the view of the comet's nucleus.
