We actually see this more obviously in the radio emissions from Jupiter because when solar storm hits us, we not only just see the optical light, which is aurora, but we also have radio signals from the solar storm interact with the magnetic field.

Yeah, so Saturn also has auroras observed by the Hubble Space Telescope, but I don't believe any of Saturn's moons interacting with it in such an interesting way.

Do we see auroras on planets outside of the solar system?

Currently, we actually don't have the capability of observing auroras around planets around other stars yet, but we're actually hoping to be able to observe them soon.

Many planets orbit very close to their host star, so we expect the planet's magnetic field will interact with their host star's magnetic field, similar to how Io interacts with Jupiter's magnetic field.

And when their host star's solar wind passes through this interaction, we expect to observe radio moderations corresponding to the orbital period of the planets.

And this radio signal current is not reachable with

this generation of radio telescope.

But as you know, Australia is building the square kilometre array that will be a lot better at observing radio signals in the outer space.

And we're hoping to use the SKA to detect this kind of signal in the next decade.
