SUMMARY: New images taken by NASA's Deep Impact spacecraft show the actual nucleus of its target, Comet Tempel 1. The nucleus is the heart of the comet, and largely composed of ice and rock. Surrounding that is a halo of gas and dust that largely obscures the view. Tempel 1 isn't a sphere, but an oblong potato-shaped object, 14 km (9 miles) long by 4.8 km (3 miles) wide. By continuing to watch the nucleus as it approaches, Deep Impact will provide scientists with a better idea of the comet's rotation and orientation, so they can fine tune the final collision on July 4.
