July's cosmic collision between Jupiter and Comet Shoemaker-Levy 9 has presented many paradoxes and puzzles for astronomers, space physicists, and planetary scientists. For a start, the more that scientists analyze the data, the more that questions arise, and the deeper become the valleys in the debate. Indeed, synthesizing the data from the literally hundreds of thousands of assorted images, observations, and measurements has proven to be a daunting task for the entire space science community. And one that was still getting off the ground at last week's annual American Astronomical Society's (AAS) Division of Planetary Sciences meeting here.
Though some clear ideas about what happened were emerging by the end of last week, the community was still divided over many fundamental questions.
