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 dwarf's aurora is mainly red in colour because the charged particles are mainly interacting with hydrogen in its atmosphere. On Earth, the greenish glow is caused as the electrons from the Sun hit oxygen atoms.
