A regular period for Saturn's magnetic field that may track its internal rotation
Article Abstract:
A study reveals that it is difficult to determine Saturn's rotation, as there is no solid surface from which to time it and the alternative, the magnetic field is nearly symmetrically aligned with the rotation axis. The magnetic field measurements revealed a time - stationary magnetic signal that appears to be stable in period, amplitude and phase over 14 months of observations, pointing to a close connection with the conductive region inside the planet, although its interpretation as the 'true' inner rotation period is still uncertain.

Anti-planetward auroral electron beams at Saturn
Article Abstract:
Measurements by the Cassini spacecraft in Saturn's magnetosphere reveal electron distributions on near equatorial segments that contain electron beams which are strong aligned with respect to the local magnetic field and have great similarity to those observed at Earth. The energy fluxes in the anti-planetward accelerated beams compete with the fluxes contained in the beams that are directed towards the planet, and therefore generate aurorae.

Titan's lost seas found
Article Abstract:
The surface images taken by the Cassini spacecraft revealed lakes is formed by the second most abundant component of the Saturnian moon Titan's atmosphere, methane unlike water found on Earth. The fact that the lakes are found only at high latitude in Titan's northern hemisphere point that they expand during the winter and shrink in the summer as a result of increased evaporation.
