Jupiter’s North Pole Unlike Anything Encountered in Solar System

Ignoring all the fascinating stuff about Jupiter, let me point out this gem: <i>The download of six megabytes of data [...] took one-and-a-half days</i><p>I sometimes like to scare kids by telling them about the time when I surfed the Internet with 14.4 kbit modem, but even that looks incredibly fast compared to the speed of interplanetary data transmission (back then, 6 MiB would have taken me about 2-2.5 hours).<p>(NB that I am not complaining or anything, just pointing out that this is many orders of magnitudes slower than anything one would normally consider a &quot;slow&quot; connection.)

<i>“Saturn has a hexagon at the north pole,” said Bolton. “There is nothing on Jupiter that anywhere near resembles that. The largest planet in our solar system is truly unique. We have 36 more flybys to study just how unique it really is.”</i><p>This is the first I&#x27;ve heard of Saturn&#x27;s hexagon, very interesting: <a href="http:&#x2F;&#x2F;www.space.com&#x2F;30608-mysterious-saturn-hexagon-explained.html" rel="nofollow">http:&#x2F;&#x2F;www.space.com&#x2F;30608-mysterious-saturn-hexagon-explain...</a>

Absolutely breathtaking.<p>Interesting that they phrase the headline almost as if to imply uniqueness. My impression was that Saturn&#x27;s hexagon was the unique situation (occurring, hypothetically, only under very specific conditions). Is it expected then that Uranus and Neptune&#x27;s poles will look different still?

I understand Juno flew as close as 4,200km. Are there any pictures from that distance? The closest here says it was taken from 38,000km.

I wonder if the clouds don&#x27;t separate into bands as much at those latitudes because the velocity (due to the planet&#x27;s rotation) is lower closer to the poles.

There are only 8 planets in the solar system (well, 9 with Pluto). &quot;Unique&quot; isn&#x27;t a terribly high bar here.

the second video says:<p>&gt; the infrared data captured a faint aurora<p>when talking about aurora strength which variable is predominant: the magnetosphere, the atmosphere, or amount of solar radiation?<p>also, can anyone speak to the reason for the noisy instrument detecting those 3.45 micron wavelengths? why is the bottom edge so active?

&quot;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.&quot;<p>...surely that&#x27;s a typo and they mean gigabytes?

Jupiter is &#x27;truly unique&#x27; because it <i>doesn&#x27;t</i> have an extremely puzzling feature that only one other planet is known to have?

based on the obvious banding from the side i always assumed the top might in fact look like a hexagon.. looking forward to seeing more!!

Where does that infrared heat orginate? Fission?
