Origin of the obliquities of the giant planets in mutual interactions in the early Solar System
Article Abstract:
The obliquities of the giant planets were achieved when Jupiter and Saturn crossed the 1:2 orbital resonance during a specific migration process and different migration scenarios cannot account for the large observed obliquities. The existence of the regular satellites of the giant planets does not represent a problem in this model because, although they formed soon after planetary formation, they can follow the slow evolution of the equatorial plane it produces.

Energetic neutral atoms from a trans-Europa gas torus at Jupiter
Article Abstract:
The magnetospheres, or space environments, of magnetized planets produce considerable quantities of energetic neutral atoms at energies varying from tens of electro n volts to hundreds of kiloelectron volts. The energetic atoms are the product of charge exchange between energetic ions that are magnetical ly trapped and cold neutral atoms, and they transport considerable volumes of energy and mass from the magnetospheres.

Secrets of the deep
Article Abstract:
In the solar systems, the magnetic fields of Uranus and Neptune are different from those of other planets, as their fields are effectively tipped over. The fundamental process-convection in a rotating spherical shell of electrically conducting fluid- explains the basic structure of all the dynamo-generated planetary magnetic fields.
