"Weird hexagon on Saturn is way bigger than scientists thought."

"As the polar vortex became more and more visible, we noticed it had hexagonal edges, and realized that we were seeing the pre-existing hexagon at much higher altitudes than previously thought."

Saturn?

At first glance I thought that was video of a colonoscopy of Uranus.

I am Laslo.

A Saturnine Hex. Who knew.

rehajm म्हणाले...

That’s very interesting. Cold temperatures plus spinning plus strange gasses?

I could make weird shapes with ice cream recipes and the mixer.

Any pattern with high symmetry is not unusual naturally.

The unlikely-to-be-found scientific challenge is to come up with a dynamic system with that pattern as the saturated fastest-growing-mode.

Earth has Rossby waves, the edges of which are the jet stream, much more chaotic.

"Weird hexagon on Saturn is way bigger than scientists thought."

How can this possibly be? There was a consensus. And it was peer reviewed!

exhelodrvr1 म्हणाले...

Anonymous senior White House source states that they are desperately trying to keep Pres Trump from making the hexagon bigger.

So it looks like a standing wave imposed on the otherwise circular path of the winds. ( Wavelength = 1/6 the circumference of the circle at that latitude. )

Saturn gets much less sunlight per square unit of surface area, plus a much deeper cloud cover, which would result in much more stable weather patterns than on Earth.

George Grady म्हणाले...

The earth's got one of those, too: the jet stream.

The Cracker Emcee Refulgent म्हणाले...

It’s good to have Laslo back.

Original Mike म्हणाले...

Is it bigger than Earth? Because the Althouse vortex is the size of our entire planet.

Ralph L म्हणाले...

Way Bigger! Science at its best!

Since one of those is a weird hexagon then no, the earth does not.

The trick is to account for the hexagonal shape.

Resonance?

Nonapod म्हणाले...

It's certainly weird. I guess it has something to do with fluid dynamics of different densities of materials rotating at different rates causing the formation of vortices or gyres at regular points. I remember reading about how they were able to generate various polygons in the lab by altering the rotational speed or something.

chickelit म्हणाले...

Saturn is hexed.

Bob Boyd म्हणाले...

Don't worry, Jupiter. Weird hexagons are just a fad. The giant red spot will stand the test of time.

Sorry, your little brother does more interesting things.

WK म्हणाले...

I am sure it is not this. . . scientists and all . . .
What does hexagon tell us about instrument that captured image?

It tells us that the aperture contains either three or six blades and that where these blades meet there is a corner which results in Fraunhofer diffraction.

But since the rest of the image is round . . .

Based on the all-seeing eye, I assume you are Sauron.

”The giant red spot will stand the test of time.”

In recent years the Great Red Spot has become the Dull Brown Spot. My getting a telescope probably has something to do with it.

Walter S. म्हणाले...

Hmmm. Look at a soccer ball. Some patches ought to be round (if you think only about each patch by itself) but they are hexagons because they have to fit with the patches next to them.

On Saturn, there must be six large structures surrounding this one. That seems simpler than a six-cycle wave along the boundary or an camera effect. But what are the structures? They can't just be six big rotating clouds like the center one, because they would clash with each other. It's a puzzle. I'll bet the scientists are having fun!

rehajm म्हणाले...

Voayager found this hex back in ‘82 I see. And they still haven’t figured it out?

n.n म्हणाले...

We're still exploring our solar system, not to mention our own planet. We have only made a cursory near-observation at the edge of our solar system. We do not even have a consensus when human life begins. A substantial minority place their faith in Stork. Yet, the universe and time are our oyster.

WK म्हणाले...

It’s YUGE!!!!!

I wonder how many people think there is a giant purple spot on Saturn’s butt.

In fact, the shape of the jet stream, which separates the polar vortex from the warmer air closer to the tropics, often looks roughly polygonal, even hexagonal, when the Arctic oscillation switches from its summer pattern to its winter pattern. Of course, the earth one is a lot less stable than the Saturn one, since earth's atmosphere is interacting with the physical topography, and the earth's year is much shorter. So, well, at times, the earth does indeed.

I'll call it fake news since they don't mention the fact that the colors are fake (text not in the article: color, light, wave).

Real colors.

Mr Wibble म्हणाले...

If you fall through it, you'll end up a centaur or a giant praying mantis.

Fernandinande म्हणाले...

A couple more Drudge fake news headlines.

"Four UFOs spotted over Trump golf course..."

Ceiling lights reflected in a window.

"Burglar jailed after beaten up by monkeys..."

The drunk guy fell and broke his leg while the squirrel monkeys hid from him.

Pournelle and Nevin predicted this in Foot Fall.

Ignorance is Bliss म्हणाले...

It's the alien's military command headquarters. What chance do we have, when they have a hexagon, and we only have a pentagon?

Trump should order the immediate construction of a new, seven-sided military command building!

NotWhoIUsedtoBe म्हणाले...

A septodon.

Skip that and go straight to octogon.

DonaId, Pursuant to your Executive Order on the new Space Force, we must ship all of the Deplorable Drumpf Trolls (DDT) up Uranus to spare Earth from any more of their inanus.

DanTheMan म्हणाले...

>>What am I, chopped liver?

Look, Jupiter... first you failed in your efforts to become a star. You just didn't have right stuff. Then you decided you'd get a ring, too, just like your neighbor. Then you went on and on about your "Great" red spot, which lately you've just been phoning in.

So, yes, your kid sister gas giant is getting all the press these days. Just face it, she's beautiful and a lot more appealing than you are. She even has a little friend with some real atmosphere.

Maybe you should give that nuclear fusion thing another go, and try harder this time, OK?

Jess म्हणाले...

Scientists have pretty well explained the shape through computer models, but that's not nearly as exciting as atmospheric aberrations caused by aliens.

DanTheMan म्हणाले...

Trumpit, your seat on the "B" ark is confirmed. Right next to the telephone sanitizers and management consultants.

rhhardin म्हणाले...

You can't cover a sphere with hexagons. You need 12 pentagons somewhere. So they go together.

Hey I can see Uranus.

No, I mean the planet.

Burt Reynolds dead at 82.

Star of Smokey and the Bandit, Cannonball Run, and Gator.

He will be missed.

Julius Caesar worshiped me as the greatest of the Gods. You knew that, right? Julius was the Man, you guys aren't a pimple on his butt. But you managed to hack together a telescope or two, and now you're laughing at me 'cause my spot turned brown. Oooh, that gets my sacrificial goat! Let's see how attractive you are in 300 years or so.

You want fusion? I'll show you fusion. I'll huff, and I'll puff ....

You're gonna think Global Warming. The Joviogenic kind.

MAJMike म्हणाले...

Must be caused by ancient aliens.

rcocean म्हणाले...

Burt Reynolds best movies:

Deliverance
Sharkey's machine
Longest Yard
Smokey and the Bandit
The End.

God has a wrench that fits that hex nut.

>>You're gonna think Global Warming. The Joviogenic kind.

Go home, Jupiter, you're drunk. I think you've had one equatorial "belt" too many, if you know what I mean and I think you do.

Yes, Julius worshipped you. And on the Ides of March, when he really needed you, where were you, huh? Probably just screwing around with the asteroid orbits again.

Look, you didn't even get around to naming your moons. You had to rely on Galileo to do that for you.

And don't get me started on why it takes you 12 years to do just one orbit...

Birkel म्हणाले...

Burt Reynolds was good in Boogie Nights, too.
He wasn't the star but it was a good movie, to my mind.

Deliverance and Smokey and the Bandit are one and one-A.

Char Char Binks, Esq. म्हणाले...

It's beautiful!

Birkel म्हणाले...

Char Char Binks,
I looked, and you, sir, are correct.

Andrew म्हणाले...

Is this a cafe?

Where do we get to discuss Cory "Doofacus" Booker?

rcocean म्हणाले...

Burt Reynolds was BIG Star in the 70s and 80s. Which is a little late for the boomers. And since they dominate our Culture, I wonder if Burt will get much publicity.

No doubt the boomers are still wondering why John left the Beatles or crying over that scene in "To Kill a Mockingbird".

We Know(TM) that the reason Saturn is cold is because there is not enough CO2. the Sun has nothing to do with the situation.

Given that the ice caps on Mars are shrinking, I think we need a new term here...
