Summary

Greenbelt, Maryland—Just last summer, planetary scientists learned that the Jovian moon Ganymede has a magnetic field and perhaps a trace of an atmosphere (Science, 19 July, p.311 and p. 341). Now, with the help of a Hubble Space Telescope spectrograph, they have detected yet another planetlike feature: hints of an aurora at Ganymede's poles.
