Cassini also carries tools to study cosmic dust around Saturn, as well as the planet's auroras and its odd magnetic field. |
By knowing how auroras react to the solar wind, scientists can better determine the impacts of space weather in the future. |
The Roman philosopher Seneca proposed that the auroras were flames slipping through cracks in the heavenly firmament. |
On Earth, UV and radio aurorae are more frequent around 22-24h Local Time, while more around 8-12h in the case of Saturn. |
On Earth, aurorae are caused by the interaction of solar wind particles with the planet's magnetic field. |
A typical example of how both missions will co-operate is the study of the magnetic substorms producing the bright aurorae. |
