Exoplanet Has Showers of Pebbles

CmdrTaco posted more than 4 years ago | from the gonna-need-a-thicker-umbrella dept.

Space 341

mmmscience writes "The newly-discovered exoplanet COROT-7b has an unusual form of precipitation: rocks. Because it orbits so close to its sun, the temperature on its sun-facing side is around 4220 degrees Fahrenheit. That's hot enough for rocks to vaporize — not unlike water evaporating on Earth. And, like Earth, when the vapor cools in the upper atmosphere, it forms clouds and begins to rain. But instead of water, COROT-7b gets a shower of pebbles."

Re:Wow What a Nigger! (-1, Troll)

Anonymous Coward | more than 4 years ago | (#29607005)

HOW TO BE A WORTHLESS, VILE, AMERICAN YARD-APE!!!!
  • Slink around, shuffling your feet and bobbing your neck like the lazy retard you are.
  • Walk down the middle of the street because you don't know what a sidewalk is for.
  • Hang out at carwashes and mini-marts because everybody knows these are the best places to be a dope, I mean dope.
  • If you're a nigger bitch, shit three nigger babies into the world before 17 years of age. This assures that welfare money will support you, so your nigger men have more time to commit crimes.
  • And give REAL honest black people a bad name.
  • Oh yes, make sure each nigger baby has a different father.
  • Bastardize the English language in the name of nigger culture.
  • Make sure that several terms have multiple meanings and others have ambiguous meanings and that only 50% of nigger words are even complete words. Real niggers will know what you're trying to say.
  • As a culture, make sure there are always more blacks in prison than in college at any given time.
  • Hang out in packs of 10 to 15 and make sure everyone acts as annoying as possible. This helps to promote nigger individuality.
  • Always talk loud enough so everyone in the 'hood can fucking hear you, and if they are niggers, they will know what your saying, bro.
  • Wear clothes that are 10 sizes too big, making sure the pants hang off your ass.
  • Park at least 5 junk cars in your yard while being careful not to use the driveway. It's OK to abandon them in the street as long as it's in front of someone else's crib.
  • Exaggerate every motion, every tonal inflection and grab your dick a lot.
  • Do drugs, sell drugs, make drugs. Okay, don't REALLY do this, but it IS what niggers do.
  • Turn your backyard into a junk yard. If you don't have a backyard, turn your mother's into a junk yard.
  • Travel around leaching off relatives, friends, salvation armies.
  • Drink cheap wine and malt liquor every day, forgetting that "malt liquor" is just fortified cheap beer.
  • If you're a nigger buck: fuck anything that moves, no matter how ugly she is. After two 40oz, even the ugliest, fattest nigger bitch will look good.
  • Be charitable and covet fat, ugly white chicks. After all, they're niggers too. They can't help being so undesirable to white men that they have to fraternize with black dudes on a 20/20 trip. And white ho's are a special trophy too, especially the not so ugly ones.
  • Spray paint everything in sight with scribbles that mean nothing to white people but mean things to fellow niggers (except niggers from another hood who will probably go after you for tresspassing on their turf).
  • Use the term "motherfucker" in every sentence. It's one of the most versatile words in the nigger language, being a noun, verb, adjective and complete mini-sentence in event you run out of thoughts.
  • Stop in the middle of the street, blocking all traffic to converse with fellow niggers and have complete disregard for everyone else.
  • Overcharge customers at Taco Bell and pocket the difference.
  • Drive your car while slouched so low that you can barely see over the wheel (gangsta drivin').
  • Get a job under affirmative action. Then sit around all day pretending that you earned the position and that the other co-workers respect you. Whenever you fuck up, scream "racism!" & hope you get enough Generation X liberals in the jury.
  • Never, I mean NEVER, take any responsibility for your actions. Always blame others including Asians, Latinos, Mexicans, and especially Whites for your sorry ass stupid lives.
  • Be sure to get a dog, tie it up in the cold and mud and neglect it until it dies. Then start all over again. Cash must be used because you long ago fucked up your credit and checking account.
  • Cram 5 generations into a two room government apartment and still be able to neglect your kids.

Then you too can be a true nigger, and anyone who finds any fault with anything you do is automatically a racist. They don't dislike what you do and wish you would do something better with your life, nor do they wish you would realize that other people exist and should be treated with respect. No, they're just racists who hate you because of the color of your skin, and everything bad in your life is their fault. You nigger.

I'm going to make an educated guess, and say it's in the same way we "know" that it rains any kind of rock at all -- because that's what the simulations said. It says they even varied constraints based on not knowing exactly what the composition of the planet is, but they kept ending up with the same basic result.

So it all comes down to how good the simulation model is. It's possible it's inaccurate in a way that it is right that there is rock-based precipitation, but that it's in liquid form, but I certainly have no idea.

Re:Summary inaccurate (5, Interesting)

clone53421 (1310749) | more than 4 years ago | (#29606643)

True. Also, I'm wondering if "pebbles" is an appropriate description of the condensed rock or if it wouldn't be more aptly described as "sand" or even "dust". Raindrops stick together; depending on how quickly the rock condenses, it might not have time to grow very large. (Then again, it could grow like hail, if the rock was in the liquid state for any significant amount of time.)

Re:Summary inaccurate (2, Funny)

MickyTheIdiot (1032226) | more than 4 years ago | (#29606813)

Sockatume (732728) | more than 4 years ago | (#29606719)

To be fair, the original press release also mangles observed and simulated results like crazy. They've definitely found the exoplanet and determined its orbit and mass. They've either confirmed or hypothesised from simulation that there are no volatile compounds on or around the planet, which they hypothesise is due to bake-out. They've hypothesised based on simulations that it is likely to have a rock-based atmosphere which, depending on composition, could be verified spectroscopically.

Just like the earth has water vaporizing from the oceans instead of salt, I would assume there would be an equivalent there. Since oxides and silicates tend to melt and vaporize at temperatures higher than metallic elements, it might be metallic rain. Which cooling and falling would end up a very unpleasant form of shrapnel.

Rock Rainbows? (4, Interesting)

MarkRose (820682) | more than 4 years ago | (#29606703)

Given that different material will have different melting temperatures, that should lead to the different metals coalescing at different heights. At sunset, there ought to be a layering affect as the last rocks fall back to the surface, a rock rainbow in effect. Of course, it probably won't last long with the whole planet being molten.

Re:Rock Rainbows? (4, Insightful)

I would also observe that "molten rock" is not famous for its transparency, let alone "gaseous rock". It may be an "atmosphere", but there won't be anybody observing any sort of "rainbow". The word "atmosphere" may be deceptive in this context; think less "open sky" and more "sea of blindingly hot lava so hot it's gaseous, not that you have any reason to care about this distinction".

Re:Rock Rainbows? (1)

FlyingBishop (1293238) | more than 4 years ago | (#29607421)

What if the life forms are made of gaseous lava? Around Earth surface temperature, I can see the arguments for most life forms being carbon based (though I've heard silicon could have similar properties.)

But at high-energy states like that, it's kind of absurd to begin theorizing about what would or wouldn't be damaging to a life form that evolved in that environment.

Having parked under a tree during a hailstorm, how is this different from something as solid as hail raining down on you?

Ice is pretty solid and it's created by pretty much the same phenomenon as the pebbles in this planet. All you need is a temperature range between solid to gas of a substance and a rotation speed slow enough to cool the other side by radiation.

But I'm not going to shout down any scientist who's spent enough time to measure the spectra, do the math about temperatures and conclude this ... because science is good.

It is nearly impossible to imagine a deluge of pebbles falling from the sky, or turning on the morning forecast to hear reports of "rocking" instead of "raining."

Oh I can imagine it. You see dark clouds roll in, crowding around. In the distance but growing louder, the rapid heavy percussion of the rock shower begins. Then in the cloud at the front, you see a flash of light and a shower of sparks like a pyrotechnic burst. Seconds later, instead of a crash of thunder, you hear the wail of an electric guitar.

It is now rocking. Rocking hard core.

Solid precipitation and dinnerplate planets (2, Interesting)

SMoynihan (1647997) | more than 4 years ago | (#29606781)

Having read TFA, I am interested why the authors hypothesise that the precipitation is as solid rocks. Intuitively, it would make more sense that it would be in a liquid phase (while I have no idea of what pressures would exist on the planet, and am no geologist, liquid rocks seem to exist across temperature ranges in excess of 100's of degrees here on earth.) Admittedly, the article does seems to imply that there is no rotation of the planet, and thus gaseous rock migrating to the super-cold side might (possibly) precipitate rapidly. In fact, would this imply that there is a large scale migration of rock from the sunward side of the planet to that opposed to the sun (and would this in turn alter the fundamental planet shape? I envisage dinnerplate planets...)

Re:Solid precipitation and dinnerplate planets (2, Interesting)

Shotgun (30919) | more than 4 years ago | (#29607121)

I would expect that the elements/molecules with higher melting points would migrate to the sunward side, while more volatile stuff would end up in the shadows. Would you have something like a "shield" of aluminum oxide guarding an ocean of iron?

slyborg (524607) | more than 4 years ago | (#29607105)

Some hyperbole here.

The Castle Bravo test shot (http://en.wikipedia.org/wiki/Castle_Bravo) was one of the largest thermonuclear detonations ever, with an estimated yield of 15-22 MT. The blast crater from Bravo was 2000m in diameter and 75m deep. Assuming it was square because I'm too lazy for math today, that's about 300,000 cubic meters. Assuming that this was blasted in solid granite (http://www.allmeasures.com/Formulae/static/materials/32/density.htm) you get about 780k metric tons.

However, most of this material wasn't vaporized, it was pulverized by the shock wave and propelled as a solid into the mushroom cloud. The actual quantity of material melted I wouldn't hazard to estimate, but it was a small proportion of the overall material excavated.

Much as in the "it's raining rocks!" planet, this precipitation would be much closer in form to dust, not "pebbles". One of the reason that water on earth comes in larger forms is that the water molecule has a charge, and will aggregate electrostatically. I don't think that would be true of this silicate cloud.

Meanwhile on COROT-7b scientists find a new planet so cold that water would actually create "oceans" on the surface , and even freeze at the poles.

They laugh at the though ever existing on that planet.

Reality Stranger than Fiction (2, Insightful)

My first reaction was that this (assuming the theory is correct) is about as cool of a discovery - concept I've read about in a long time. At the same time it brings to point a thought that one of the problems with popular Sci-Fi is that it misses on potential of "stuff" "out-there" (space) being wilder and different (including life) than we've yet to imagine.

If you consider the variety of habitats that we find life in our tiny part of the cosmos (Earth) and that life keeps being discovered in more and bizarre places (by human standards) when you extrapolate that out, I tend to think it may be literally beyond our imagination.

If we, by whatever means, met intelligent life, would we be able to communicate; sure math is universal, but consider the issues communicating ideas and values across cultures when its the same species. Consider a collective consciousness, what does the term "I" or "me" mean to it (them).

FTA:

It is nearly impossible to imagine a deluge of pebbles falling from the sky, or turning on the morning forecast to hear reports of âoerockingâ instead of âoeraining.â

Does this seem difficult to imagine, let alone nearly impossible?
Imagine, if you can, something somewhere else very similar to something standard here!

I'm sure the methane based party animals on Titan also point to Earth and oooh and aaah about how solid H2O actually melts, vaporizes, and falls from the sky as rain, hail, and snow under the tremendous heat we have here.

Minerals melt and boil at various temperatures and at 2,370 C most minerals will probably break down into smaller molecules and atoms. Since Silicon dioxide (quartz) is a stable and common component of various kinds of rocks, and it has a boiling point of 2,230 C, I suspect that the surface is a sea of melted and boiling quartz and that most of the "atmosphere" is gaseous quarts, and that the "rain" is droplets of liquid quartz. Aluminum oxide melts at 2072C and boils at 2,980C, so the "ocean" is probably a mixture of the two minerals. 2,370C is enough to boil Silicon but not Aluminum. http://www.science.co.il/PTelements.asp?s=BP [science.co.il]
