Part of situation: Beta Pictoris b radio signal detection (2 clusters)

Beta Pictoris b exoplanet yields first direct radio signal detection

exoplanet radio signals Beta Pictoris b magnetic field aurora

Astronomers have achieved a major milestone by detecting and localizing radio signals originating directly from an exoplanet, Beta Pictoris b, rather than its host star. The gas giant, located approximately 63.4 light-years from Earth, was observed using the MeerKAT radio telescope array in South Africa during four sessions between 2025 and 2026.

The detected signals consist of brief, repetitive, and highly circularly polarized radio bursts in the 0.85 to 3.5 GHz frequency range. Researchers attribute these emissions to auroral activity, likely driven by the electron cyclotron maser instability (ECMI). This phenomenon occurs when charged particles interact with the planet's intense magnetic field, similar to the auroras seen on Earth and Jupiter.

By using distant quasars as precise reference points, the international research team—including scientists from the Harvard-Smithsonian Center for Astrophysics and the University of Oregon—was able to definitively distinguish the planetary signals from those of the host star. This discovery allowed for the first direct measurement of an exoplanet's magnetic field strength, estimated to be at least 1.25 kilogauss, which is thousands of times stronger than Earth's magnetic field.
