Aurora found beyond our Solar System

Brown dwarf

The brown dwarf’s aurora is red and up to a million times brighter than the Earth’s northern lights

An aurora has been spotted outside our Solar System for the first time, scientists report.

An international team detected the light display around a brown dwarf about 18 light years away in the Lyra constellation.

They say the luminous glow looks like the northern lights, but is up to a million times brighter and more red than green in colour.

The findings are reported in the journal Nature.

Dr Stuart Littlefair, an astronomer from the University of Sheffield, said: “This is the first time that we have confirmed we are seeing auroras on brown dwarves.”

Shimmering auroras are some of the Earth’s most dazzling displays. This luminous glow can also appear around all the planets in our Solar System.
