Tucson, Arizona — When Galileo discovered Ganymede four centuries ago, little did he suspect that the third satellite from Jupiter might be glazed over with the very substance he was breathing.
It took modern astronomical instruments and chemical knowledge for scientists to detect the oxygen and ozone that coat Ganymede. Now, two planetary scientists affiliated with the California Institute of Technology have developed a theory to account for the presence of the substances, as well as the mechanism by which their concentrations are maintained.

PASADENA— The Galileo probe that dropped into Jupiter's atmosphere last December detected a surprisingly small amount of water. But scientists at the California Institute of Technology have new thundercloud photographs and a theory to suggest that the solar system's largest planet may be "wet" after all.

PASADENA—Caltech geologist Clarence Allen will receive the 1995 Medal of the Seismological Society of America at the society's next annual meeting in April 1996 in St. Louis, Missouri. Allen, a professor of geology and geophysics, emeritus, will be honored for his "outstanding contributions in seismology or earthquake engineering."
This prize is the highest medal that the society can bestow upon a member, and unlike many awards that are given on a regular schedule, the Medal of the SSA is given only occasionally, when someone worthy is identified. The last such award was made in 1993.
