Neptune's magnetosphere. Illustration of the planet Neptune (centre) and its magnetosphere (magnetic field lines shown) shielding it from cosmic radiation and the solar wind. The grey background mesh represents the boundary of the magnetosphere. Most of the charged particles from the Sun are diverted around the planet. Some are trapped and guided by the planet's magnetic field towards the polar regions, where they impact the planet's atmosphere and cause aurorae. The Neptunian moon Proteus (green) is at lower right. | |
