Jupiter's radio emissions were first discovered in the 1950s. Since then, terrestrial radio telescopes have monitored Jupiter's emissions above 10 MHz, while several spacecraft have conducted flybys of the planet or orbited it, such as Juno. The synergy between space-based and ground-based observations has made it possible to obtain complementary data, including multi-point, in situ and statistical measurements. In this presentation, we will review recent discoveries of radio emissions induced by the Galilean moons made in recent years using Juno and ground-based radio telescopes, and look ahead to future missions to Jupiter, such as JUICE. In the final part of this presentation, we will take a look outside our solar system, using Jupiter, often considered to be a miniature analogue of an exoplanet, as a benchmark to search for the giant analogue of satellite-induced radio emissions: star-planet interaction radio emissions. We will present an example of auroral stellar radio emission from the red dwarf AD Leonis, detected by the Chinese FAST radio telescope, which highlights the ability to constrain in situ parameters, such as source locations and the energy of the electrons responsible for these emissions, using tools such as the ExPRES simulation code.
