NASA reveals discoveries made following the July 4 collision between its Deep Impact probe and comet Tempel 1.
This map of comet Tempel 1 was made by scaling images taken by the NASA probe Deep Impact to about 5 yards per pixel. Arrows a and b point to large, smooth regions and the impact site is indicated by the third large arrow. NASA scientists say the comet's surface is weaker than a snowbank. The probe collided with Tempel 1 on July 4, 2005.
