This false-color image shows comet Tempel 1 about 50 minutes after Deep Impact's probe smashed into its surface. The colors represent reflected sunlight, with white indicating the brightest materials and black showing the faintest. This brightness is a measure of reflected sunlight. The Sun is located to the right, out of the picture. The blue speck in the upper left corner is a star. Credit: NASA/JPL-Caltech/UMD
