Auroras are among the most captivating phenomena on Earth, brightening polar skies with undulating ribbons of glowing charged particles. These eerie light shows have also been observed on many other planets in our solar system, leading astronomers to speculate that they might be as ubiquitous outside our stellar backyard as they are within it. New research published today in Nature bolsters this theory with evidence of radiant auroral activity illuminating the skies of nearby brown dwarf LSR J1835+3259. Led by Caltech’s Gregg Hallinan, the study demonstrates that brown dwarfs can produceauroras 10,000 times brighter than any seen so far.
