Beta Pictoris b exoplanet radio signals detected for the first time
Astronomers have achieved a scientific milestone by detecting radio signals originating directly from an exoplanet, Beta Pictoris b, located approximately 63.4 light-years from Earth. Using the MeerKAT radio telescope array in South Africa, researchers from the Harvard & Smithsonian Center for Astrophysics and the University of Oregon were able to distinguish these emissions from the signals of the host star.
The detected signals consist of fast, repeating, and highly circularly polarized radio bursts within the 0.85 to 3.5 gigahertz frequency range. Scientists believe these emissions are a natural phenomenon caused by auroral activity, driven by the planet's intense magnetic field. Calculations suggest the magnetic field of Beta Pictoris b is at least 1.25 kilogauss, significantly stronger than Jupiter's.
Beta Pictoris b is a massive gas giant, estimated to be roughly 10 to 12 times the mass of Jupiter. This discovery provides critical evidence regarding the magnetic properties of planets outside our solar system.
