I've always wanted to see auroras such as the northern lights, and wondered what other kinds of objects in space might have them too. Now astronomers have found auroras outside our Solar System.

They've detected them on a brown dwarf - a kind of 'failed star' - in the constellation Lyra. These auroras are thousands of times more powerful than the ones we see on Earth and other planets in our Solar System such as Jupiter.

Unfortunately the brown dwarf is 18.5 light years away, so maybe I'll just stick to dreaming about seeing the northern lights...

Would you like to see these auroras?

Oxygen in our atmosphere makes Earth’s auroras greenish. The brown dwarf's ones are red as its atmosphere is mostly hydrogen.
