Hubble Discovers Dark Spot on Uranus

TheDawgLives writes "Just as we near the end of the hurricane season in the Atlantic Ocean, winds whirl and clouds churn 2 billion miles away in the atmosphere of Uranus, forming a dark vortex large enough to engulf two-thirds of the United States."

Dark Spot on Uranus?

I challenge anybody to post a +5 Insightful comment about this story. It can't be done!

Don't worry, your post will get there. I admit I burst out laughing as soon as I read the headline but if you want something mildly insightful I might as well fill in something while I have the time.

Is it any surprise that there's a dark spot on Uranus? Jupiter has a couple of huge cyclones raging on in there, so does Saturn. Both the planet's black spots are bigger than Uranus' anyway. Uranus is a gas giant, since there's going to be some wind going on there I'm not exactly shocked that huge cyclones have formed.

Enormous cyclones I think are just a side-effect of gas giants. I don't think it's anything to get excited about.

"forming a dark vortex large enough to engulf two-thirds of the United States" ... tub girl ... 'nuff said. Now on to the insightful posts...

It is impressive that even with the feeble solar energy it receives there is still enough to power massive cyclones.

are you implying that the sun don't shine on Uranus ?

Uranus is different from the other planets in the fact its axis is tilted almost ninety degrees - for two periods of its 84 year orbit one half of the planet is always pointed away from the sun. From the picture it looks like right now its equator is perpendicular towards sunward. Even though its distance means it would recieve little solar heat, it does have a large surface area. I would think that right now any heat would be more or less evenly distributed because of its rotation. But it would be interesting to see if heat transport would make the atmosphere more violent when one side of the planet is always bathed in sunlight while the other is in the dark, about twenty years from now. Maybe Uranus might have violent/calm /violent phases as it travels around the sun during its "year".

Gravitational heating left over from the formation of the planets and radioactive decay both provide for heat in the cores of the planets in our solar system. For alot of detail on this subject you can look here

OK, time to salvage this from all the jokes.

From the image, it looks like the spot could be 19.5 degrees north of the equator. Years ago, I read a paper by Richard C. Hoagland, author of The Monuments of Mars: A City on the Edge of Forever (1987). Although a lot of his paper seemed like wild speculation to me, I remember one "message" he deduced from the so-called area near the "face on Mars." There is a characteristic of planetary dynamics which produces an anomoly at 19.5 degrees north or south lattitude, depending on the magnetic pole of the planet. This is related to the rotating molten core of the planet.

Jupiter's famous red spot is a 19.5 deg. south lattitude. Hoagland predicted a spot on Neptune at 19.5 degrees lattitude before the Voyager discovered it. On earth, Hawaii's Mona Loa volcano, the world's largest and continuously active volcano, is at 19.5 deg. north lattitude. (The Hawaiian islands were all made by passing over the spot where Mona Loa is now.) Olympus Mons, the largest volcano in the solar system, is at 19.5 deg lattitude. The "face on Mars" is 1/3 of the way around from Olympus Mons, at 19.5 deg. lattitude.

So the spot on Uranus (not on mine!) has nothing to do with solar energy. It is an artifact of planetary dynamics.

As an additional note- if you place a tetrahedron (a triangular pyramid) inside a shpere so that it's tip touches the north pole and it's 3 base points touch the insides of the sphere, they touch at 19.5 degrees south lattitude.

Re:Dark Spot on Uranus?

[RealGrouchy]

I'm not refuting you, since I'm not qualified to. But it absolutely bakes my noodle that planetary features would always occur at 19.5 degrees south lattitude. What forces could possibly be happening to make planets all end up with significant features at the same point?

First, he said 19.5 degrees north or south.

Second, 19.5 degrees is not a point, it's a line/locus. He's not saying that Slartybartfarst always signs on the same point on the canvas.

Third, I find your "I can't think of an explanation for these facts, therefore we would do best to ignore them" argument to be scientifically insulting. PP mentioned a geometric phenomenon that is potentially significant (astronomy is closely tied with geometry).

When you say "I'm not refuting you, but..." you reall mean to say "this is fud, but..."

A better refutation would have been to ask the following questions:

- Is this just a selective set of planetary features? (I doubt it, since these are the most prominent ones on various planets, earth excluded)

- Has our observation of planets been selective to this latitude? (We've known about Jupiter's spot for a long time, and we've scoured Mars, and we know lots about Earth)

- Are the facts presented by the parent--namely, are these features at the latitudes specified--true? (I'm too lazy to check)

Pay attention to what has been said, then ask questions, then look for the answers. How well you have done that determines whether the tingling in your head feels like pain, or like knowledge.

Hoagland doesn't explain the 19.5 degree thing, he basically says that it seems to be a result of unexplained planetary dynamics for which nobody seems to have a theory for. What is more weird than the 19.5 thing is how he claims to have figured it out, be we won't go into that. The pyramid thing is just an attempt by him to provide some sort of mathematical law expressed in geometric terms that appears to be related to these unknown planetary dynamics. Like using geometric principals to explain Keplar's orbit theory. There are lots of physical phenomena that are defined by mathamatics. Why does E = M * C^2? Why F = M * a? It's just the way Mother Nature made it. It's that way so that the universe all fits together, I guess.

any way to forecast this?

"forming a dark vortex large enough to engulf two-thirds of the United States."

I'd like to know when this will happen so I can move to, say, Canada.

I'd get a move on, since it's already engulfed 50% of the US as of 2004...

Due to the decades of jokes involving the name of this planet, and in light of the fact that a change in pronunciation during the 80's did nothing to curb the lowbrow humor, the same panel of scientists who removed Pluto from our solar system, have deciced to rename Uranus. Henceforth, this planet shall be referred to as Urectum.

Re:In Related News....

[Bob Cat - NYMPHS]

Isaac Asimov pointed out that the pronunciation 'urinous' is not really an improvemnet.

Found a what on the what now?

[0xdeadbeef]

Farnsworth: I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.

Fry: Oh. What's it called now?

Farnsworth: Urrectum. Here, let me locate it for you.

well...

I guess it didn't loosten it's asteroid belt fast enough when it got to the big dipper...

Please lay off the Uranus jokes

It just makes you look desperate for a +5 funny.

The poor planet has been the butt of far too many attempts at humor.

Hopefully we can get past all this and everything will come out alright in the end.

[mottie]

One camp of scientists believe the dark spot is raised in elevation and are thus vying to name it "the turtlehead" whereas another group believes that it is actually a hole, and is fighting to name the spot "puckered starfish". More to follow.

Uranus is a gas giant...

[Anonymous Coward]

and it has a dark spot... I wish I could say I am mature enough not to laugh, but I'm not.

Yes, but is that the P. Fry from Earth, or the P. Fry from Hovering Squid World 97-A?

Um, no...

No, no, no. I am not going to look up Uranus to see if it is full of methane gas. I'm not falling for that one again.
