Radiation belt seen beyond our solar system for the 1st time

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.
