Probing the energetic particle environment near the Sun

NASA’s Parker Solar Probe mission¹ recently plunged through the inner heliosphere of the Sun to its perihelia, about 24 million kilometres from the Sun. Previous studies farther from the Sun (performed mostly at ...

The bubble-like shape of the heliosphere observed by Voyager and Cassini

For more than five decades, the shape and interactions of the heliosphere with the local interstellar medium have been discussed in the context of two competing models, posited in 1961¹: a magnetosphere-like heli...

Rotationally driven ‘zebra stripes’ in Earth’s inner radiation belt

The distributions of energetic electrons across the entire spatial extent of Earth’s inner radiation belt are found to be organized in regular, highly structured and unexpected ‘zebra stripes’, produced by Ear...

A dynamic, rotating ring current around Saturn

The idea that there is a ring current of trapped particles encircling the Earth at high altitudes first emerged in the early part of the twentieth century. The idea proved right, and measurements of the curren...
