Figure 1: Analyzing a Cometary 'Sneeze'
This display shows highly processed images of the outburst of comet Tempel 1 between June 22 and 23, 2005. The pictures were taken by Deep Impact's medium-resolution camera. An average image of the comet has been subtracted from each picture to provide an enhanced view of the outburst. The intensity has also been stretched to show the faintest parts. This processing enables measurement of the outflow speed and the details of the dissipation of the outburst. The left image was taken when the comet was very close to its normal, non-bursting state, so almost nothing is visible.
