Researchers have successfully detected radio emissions directly linked to the exoplanet Beta Pictoris b. This gas giant is located approximately 63.4 light-years from Earth. Previous attempts to identify such signals often failed to distinguish between the planet and its host star.
The observations were conducted using the MeerKAT radio interferometer in South Africa over four sessions between 2025 and 2026. Data was collected in the frequency range of 0.85 to 3.5 GHz, revealing both continuous emissions and short, highly polarized bursts.
The detected signals suggest a magnetospheric origin, similar to processes observed on Jupiter. Scientists estimate the planet's magnetic field could be thousands of times stronger than Earth's, which is likely driven by its rapid rotation period of 8 to 9 hours.
Beta Pictoris b is a massive gas giant with 10 times the mass of Jupiter. While the planet is not a candidate for life, this discovery provides astronomers with a new method to study the magnetic fields of exoplanets, which are crucial for atmospheric preservation.
