Astronomy Picture of the Day - Cyclones at Jupiter's North Pole

Explanation: Why are there so many cyclones around the north pole of Jupiter? The topic is still being researched. NASA's robotic Juno mission orbiting Jupiter took data in 2018 that was used to construct this stunning view of the curious cyclones at Jupiter's north pole. Measuring the thermal emission from Jovian cloud tops, the infrared observations are not restricted to the hemisphere illuminated by sunlight. They reveal eight cyclonic features that surround a cyclone about 4,000 kilometers in diameter, just offset from the giant planet's geographic north pole. Similar data show a cyclone at the Jovian south pole with five circumpolar cyclones. The south pole cyclones are slightly larger than their northern cousins. Oddly, data from the once Saturn-orbiting Cassini mission has shown that Saturn's north and south poles each have only a single cyclonic storm system.

Did they fail to pay attention to their Glow Bull Warming?

The Cyclones made it all the way to Jupiter from Ames, Iowa, and NASA is still trying to figure out how to send people to Mars.

Cool. I think I saw this discussed on Rogan with Terrence Howard but don’t recall the explanation.

Wind Speed of the Rotating Cyclones
The wind speeds within these cyclones are quite violent, reaching up to 220 mph (350 kph)6. The cyclones themselves are massive, with each northern cyclone being almost as wide as the distance between Naples, Italy, and New York City6.

As you move further away from the Sun to the other gas giants one would expect the wind speeds to slow down because there is less solar energy to feed them. The opposite is true. They become closer to friction free flow so the winds get faster.

ya know what I have never seen?... those clouds moving. were told that the winds on jupiter are exceeding 900mph but with all the spacecraft that flew by and available(that I have seen), I have never seen a moving atmosphere on jupiter. surely there should be some detection of movement...

Your homework assignment!! keep a half an eye out for what im talking about. post it up if you find anything!!
