Illustration of an exoplanet's proposed magnetic field that scientists detected through radio waves.

An artist's conceptual rendering of interactions between a prospective exoplanet and its star. Plasma emitted from the star is deflected by the exoplanet's magnetic field then interacts with the star's magnetic field, resulting in an aurora on the star and the emission of radio waves.
