Astronomers have observed a radiation belt outside the solar system for the first time, imaging high-energy particles trapped by a magnetic field around an ultra-cool dwarf star around 18 light-years from Earth.
The newfound radiation belt is double-lobed, just like the radiation belts that encircle Jupiter , the largest planet in the solar system. But if the dwarf star's radiation belt were placed next to that of Jupiter, it would be 10 million times brighter.
