For the first time, astronomers have detected radio signals from a planet beyond our solar system, according to a study available on the preprint server arXiv. The landmark observation offers a new way to study distant worlds and understand how they interact with their host stars and the environments that surround them.
Radio signals can carry clues about a planet’s magnetic field and its interaction with the star it orbits—information that can be surprisingly difficult to tease out from the tiny amount of light reaching Earth. By detecting and studying these signals from exoplanets, scientists can begin to build a clearer picture of the…
