<p>The whistler mode chorus emission in the space around planets is an important wave that plays a significant role in phenomena such as aurorae and "space weather". The generation mechanism of the chorus emission and related phenomena have been the subjects of active research, employing theoretical approaches and investigations using spacecraft. Recently, a research team from the National Institute for Fusion Science and the University of Tokyo conducted an experimental study on this topic using the "artificial magnetosphere" RT-1 device. They discovered that plasma confined in a dipole magnetic field can spontaneously produce a chorus emission. They also clarified the conditions necessary for its generation. The chorus emission is a common phenomenon observed in the magnetospheres of planets other than Earth, such as Jupiter, and is also closely related to fusion plasma waves. It is expected that this research will deepen th
