Seeing the lightning flashes only in the taller clouds (the whitest/highest parts catch the most sunlight) makes me think that convection cells and the resulting large-scale charge separation that causes lightning must be a universal thing. Considering how vastly different Jupiter's atmosphere is from ours, chemical composition is apparently an afterthought.

    NASA's animation team also simulated lightning that would be visible if you were actually viewing one of Jupiter's thunderstorms in person. The camera's point of view for the animation was generated by citizen scientist Gerald Eichstädt, using composite images of the planet and its moon.

Hahah, semi-fake, at least! I hate when people mix data and simulation without a massive all-caps disclaimer.

I was wondering, because for the flashes to be that large, seemingly illuminating an area a significant fraction of the size of Earth, it'd be likeeeeee mega lightning. But then I thought, hey, that may even be the case.

But yeah I got got. My curiosity reserves are now exhausted for the day.

Hahahaha. I love to think of myself as so ungullible.

Heh, I fell for it too. Must have been the Vangelis credit that made me suspicious.

Speaking of sounds, we've basically known that Jupiter has lightning ever since Voyager did a flyby.

The video below is magnetic field wave observations converted into audio. Doesn't even need to be shifted in frequency, it fits well within the audible range.

Be sure to read the description:

I've read that there is water vapor in Jupiter's atmosphere. Maybe that can explain the charge imbalance necessary for lightning?

I'm aware of two hypotheses: water solidifying into mushballs in the pressence of ammonia acting similar to how hail does it through friction/collisions, and shallow lightning where ammonia prevents water from freezing entirely.
