Beta Pictoris b: Astronomers detect radio signals from exoplanet
Astronomers have achieved a scientific milestone by directly attributing radio signals to an exoplanet, Beta Pictoris b, located approximately 63 to 64 light-years from Earth. Using the MeerKAT radio telescope array in South Africa, a research team led by Kevin Ortiz Ceballos observed repeating radio bursts between 2025 and 2026.
The signals were confirmed to originate from the gas giant rather than its host star with over 99.999 percent statistical certainty, utilizing distant quasars as reference points. The emissions are natural, caused by auroras resulting from charged particles interacting with the planet's intense magnetic field.
This discovery allows for the first direct measurement of an exoplanet's magnetic field strength, estimated to be at least 1,250 Gauss—approximately 2,500 times stronger than Earth's magnetic field. Beta Pictoris b is a young gas giant with a mass roughly 10 to 12 times that of Jupiter and a rapid rotation period of eight to nine hours.
