You can go to the JPL Galileo Home Page to find out. What we know so far is that the Jupiter probe did, in fact, enter the atmosphere as planned, and remained intact long enough to telemeter about an hours worth of data to the mother ship. This information will be relayed to the Earth during the next few months. We hope to learn a lot about the chemical components of the Jovian atmosphere, whether water and organic molecules exist there as many astronomers expect. We will also learn how much hydrogen, helium and possibly deuterium is present which are important elements for testing various cosmological models of the evolution of the universe. This is an exciting time for planetary scientists. In the next 2 years, the Galileo orbiter will also return thousands of pictures of the surfaces of some of the Jovian moons, unfortunately, in order to insure success for the Galileo probe, all of the close ups of Io were erased. Some had a resolution of a few dozen FEET!
