Astronomers Find First Radiation Belt Outside Our Solar System – 10 Million Times Brighter Than Jupiter’s

High-resolution imaging of radio emissions from an ultracool dwarf shows a double-lobed structure like the radiation belts of Jupiter.

A team of astronomers has successfully observed the first radiation belt outside our solar system, using an array of 39 radio dishes. The radiation belt, found around an ultracool dwarf, is similar to Jupiter’s but 10 million times brighter. This breakthrough in the study of magnetic fields…
