Observations from Earth showed that Jupiter has a massive magnetosphere and that the planet emits radiation at radio wavelengths.
Some of the currents that flow through the magnetosphere can flow down along the Earth's magnetic field to form two ovals of current centered on the north and south magnetic poles.
August 2 marked the beginning of 10 days of flares and explosions that would stir up the magnetosphere and radiation belts of Earth.
Like the Solar Wind, the magnetosphere is full of plasma, consisting of ions and electrons.
Unlike Earth, which sits inside a protective magnetic shield called the magnetosphere , Mars does not have a global magnetic field to protect it from solar flares and cosmic rays.
I work in planetary science, which includes very different fields like geology, atmospheric science, and magnetospheric studies - fields that rarely overlap.
Though magnetospheric physicists have long puzzled over the mechanism that accelerates the particles inside Earth's cavity, recent observations suggest that the Van Allen radiation belts act as a sort of cosmic particle accelerator.
For those measurements, Hasegawa says, scientists will have to wait for a future generation of magnetospheric satellites.
The observations showed a bending of the magnetic field, with the magnetospheric plasma being slowed and deflected by the moon.
A major finding of the magnetospheric imaging instrument is the discovery of a new radiation belt just above Saturn's cloud tops, up to the inner edge of the D-ring.
