Harvard Scientists Detect Radio Signal Directly From an Exoplanet

Astrophysicists from Harvard and the University of Oregon say they have directly detected radio emissions from an exoplanet for the first time, using South Africa's MeerKAT telescope. The signal from gas giant beta Pictoris b, 64 light-years away, comes from auroras and reveals a magnetic field over 300 times stronger than Jupiter's.

• beta Pictoris b is a gas giant over 11 Jupiter masses, 64 light-years from Earth
• Signal at 0.85–3.5 GHz isolated from its host star using quasars as reference points
• First direct measurement of an exoplanet's magnetic field: 300+ times Jupiter's
