Drifting through the galaxy are rogue planets, which have been flung away from their parent star by gravitational forces.
One particular peculiarity in this class is known as SIMP J01365663+0933473, a planet-size object 200 light-years away whose magnetic field is more than 200 times stronger than Jupiter's.
This is strong enough to generate flashing auroras in its atmosphere, which can be seen with radio telescopes.
