In Brief

  1. The radio signal originates from Beta Pictoris b, an exoplanet situated 63 light-years away, marking a milestone in radio astronomy.
  2. Observations made via the MeerKAT array link the radio emissions to planetary auroras driven by a magnetic field 200 times stronger than Jupiter's.
  3. The research findings have been submitted for scientific validation and are currently undergoing peer review.

In a milestone discovery for astrophysics, astronomers using South Africa's MeerKAT radio telescope array have detected the first-ever radio emission coming from an exoplanet beyond our solar system. The signals were traced directly to Beta Pictoris b, a gas giant planet located approximately 63 light-years from Earth.

According to researchers, the radio emissions are linked to atmospheric auroras generated by the exoplanet's powerful magnetosphere, which is estimated to be roughly 200 times stronger than that of Jupiter. The study detailing the breakthrough observations is currently undergoing formal peer review prior to final journal publication.
