Wave-particle interactions play a vital role in driving energetic particle dynamics within solar system plasmas. Whistler waves, in particular, play a dual role by both accelerating electrons to “killer” energies within the radiation belts and driving their precipitation from the magnetosphere into the upper atmosphere. At Earth, whistler-mode chorus waves are typically found outside the plasmasphere, while hiss waves are predominantly within it. In contrast, the Jovian magnetosphere frequently shows both chorus and hiss waves occurring simultaneously. Recent missions, such as Van Allen Probes and THEMIS, have provided invaluable insights into radiation belt electrons, whistler waves, and their wave-particle interactions at Earth. Meanwhile, the Juno mission provides a unique opportunity to reveal the typical characteristics of whistler waves and explore how whistler waves interact with energetic electrons in Jupiter's magnetosphere. In this seminar, I will discuss recent advances in understanding the global properties of whistler waves and their impact on energetic electrons at both Earth and Jupiter, using a multidisciplinary approach that combines satellite observations, physics-based simulations, and machine learning models. This comparative analysis will highlight similarities and differences in wave-particle interactions at Earth and Jupiter, providing insights into how whistler waves contribute to electron acceleration and precipitation, with implications extending beyond Earth and Jupiter to other magnetized celestial bodies.
