 Recent measurements of infrared spectra from the Subaru telescope suggest that the moon indeed contains hydrous minerals, indicating that it cannot have formed in its current position, since the hot primordial Jupiter would have melted it.It is therefore likely to have formed farther from the planet or to be a captured Solar System body.No images were taken during this flyby ("Galileo"s cameras had been deactivated due to radiation damage in January 2002), and the resolution of other available images is generally low.
