We know basically nothing about the details of cloud structure on exoplanets.

Saturn has a tilt just a bit more than the Earth and it experiences seasons; the pole is rotated something like 26 degrees into our field of vision in "winter". Uranus is actually rotating on it's side. http://www.setterfield.org/Astronomy/pictures/axial-tilt-pla...

Then it's kind of a stretch to call Jupiter "truly unique" in this respect, isn't it? "Wow, only a quarter of known gas giants are like this!"

The solar panels that Juno has produce only 500 watts of power. You would need a lot more then that to be sending gigabytes of data in any meaningful timeframe. So yes it really is just six megabytes of data taking 30h+ to download. Btw the panels would produce 14kW at earth orbit but suns power goes down quite fast as you move away from it. Also the farthest from the Sun we've ever used solar panels. Traditionally m…

Transmission is one thing, but collection is another: did they really only collect 6 megabytes of data over the course of a 6 hour flyby? Off topic, ish: does anyone know how large a solar panel array would have to be to supply all of our current energy use, if the array orbited the Sun at the same distance Mercury does?

"The download of six megabytes of data collected during the six-hour transit, from above Jupiter’s north pole to below its south pole, took one-and-a-half days." ...surely that's a typo and they mean gigabytes?
