A moon of Saturn may have 'tropical' lakes
They might not be fit for humans to swim in, but "tropical" lakes may exist on one of Saturn's moons that could harbor tiny organisms.
Scientists report Wednesday in the journal Nature that the moon Titan may have methane lakes among the dunes that pervade the tropics, the region of the moon between 20 degrees of latitude north and 20 degrees of latitude south.
Like Earth, Titan has clouds, rain and lakes, though they're made up of methane instead of water.
Scientists theorize that the conditions on Titan, which is the only moon in our solar system with an atmosphere, are capable of harboring microbial life, suggesting that organisms could live in methane lakes, as they do in water lakes on Earth.
Until recently, Titan's lakes have been observed only outside the tropical region, above 50 degrees north and below 50 degrees south. Scientists analyzed spectra of Titan's tropics gathered by the Cassini spacecraft between October 2004 and December 2008, which indicate a dark surface consistent with liquid methane.
The data suggest that a liquid methane lake present in an otherwise dune-filled, arid region of Titan. This lake would be about 2,400 square kilometers, or 927 square miles (by comparison, New York City is on 305 square miles of land).
The same Nature report discounts the possibility that the observed lake is a rain puddle, since it is present in data from 2004, before the end of Titan's dry season and the arrival of methane clouds and storms in the area. Since methane lakes aren't stable in the tropical region, the indication is that the lake is fed by an underground liquid methane stream.
These data, together with studies of other methane lakes on Titan, indicate that there's probably a subterranean source of liquid that releases methane into the moon's atmosphere and onto the surface.

Hello, you used to write great, but the last few posts have been kinda boring� I miss your great writings. Past few posts are just a bit out of track! come on!
Marvelous post praises for penning.| Insightful post, thanks for sharing! | Nice read.} {liked it on my site.|Just uploaded this to FB
I have been surfing on-line greater than three hours today, yet I never discovered any interesting article like yours. It's beautiful worth sufficient for me. In my view, if all webmasters and bloggers made good content as you probably did, the internet shall be much more useful than ever before.
Magnificent beat ! I wish to apprentice whilst you amend your web site, how could i subscribe for a weblog website? The account aided me a applicable deal. I were a little bit acquainted of this your broadcast provided brilliant transparent idea

What if there isn't any "life" and nothing resembling "heaven" out there? This is what you should be preparing to accept. They're squinting their eyes looking for the face of Jesus on a distant rock and you're praying to find a worm that lives in methane gas so you won't feel all alone. What if there is no other place to go, we're just stuck here for a brief period until we finally kill ourselves-and nothing in the whole universe (or on earth) will care?
What if space is only the realm of inquisitive dreamers and the suicidal rich, looking for a new vacation thrill?
Maybe Jimmi Hendrix was right when he moaned; "there ain't no life, nowhere".?
Be prepared for some enviornmenatlist Kollifornia professor to propose that we should send space ships up to those planets to get the water - BECAUSE WE ARE RUNNING OUT OF WATER ON EARTH !
The aliens surveying Earth in "Third Stone From the Sun" said "there aint no life nowhere" because they didnt consider earthlings worthy to be described as "Life" with all of our wars, greed, hate etc. Jimi was a very spiritual guy, he mentions God in many of his songs – I dont think he was saying that there isnt life, physical or otherwise, besides that on earth.
And exactly how is this "new" news? Anyone who follows this type of stuff will know that it was first speculated upon over a decade ago and has been widely accepted as fact for a couple of years now. What kind of "breaking news" will you have for us next? Possibly that the moon is not really made of cheese? Get back to us when you get some info that isn't already considered old by even text book standards.
Sure. It's called keeping government grants alive on earth. There's no life on that moon. It's kind of interesting to learn about the planets and the moon but you won't find life out there. Life is only on planet earth. I know I'm narrow minded.
So?...And...Just how much is this "theory" going to cost me in the form of government welfare grants to these "scientists" who never seem to actually produce anything?
About ½% of what it cost in government welfare to pay to useless people to produce nothing-except MORE useless people. If its all the same to anyone else, I'd rather pay the scientists.
If "these scientists" didn't push the boundaries of human discovery you wouldn't have half the things you use on a daily basis today. Just because they aren't making anything with a discovery like this, doesn't mean it's not beneficial to humanity and it also doesn't mean that future beneficial technologies won't come out of similar discoveries. You need to open your mind and realize that what we spend on science, as a whole, is a pittance to what we spend on almost everything else. Sad really.
What is actually mind-boggling is that some people are incapable of handling wonder, and instead let it turn to incredulity - that other hobgoblin of little minds - and so need to posit a "God" to explain everything and make it manageable and consistent for them. Go back to your cave, troglodyte.
Well, then. Some super genius named "stopthe" says belief in a higher power is stupid. I'm sure you've almost convinced yourself by now.
This is my favorite atheist argument. That people of faith believe only because they are narrow minded and can't conceptualize the wonder of the universe.
I always want to rebut that atheists only disbelieve because they can not conceptualize something outside the realm of our observation – but then I remember that it's wrong to make generalizations.
Tropical lakes on Saturn's moons? HAHAHAAHAH!!!!
Some people will believe anything, and some people will do anything to get their grants extended. This is the problem with scientists – they're bull chuckers.
More Rosetta, less Stone.
well, unfortunately, obama cancelled NASA, so we'll probly never know much more about our solar system....
Sometimes /facepalm just isnt enough...

Posted on I think any savvy company that has an asstoiaced blog knows that keeping the blog's chocolate out of the corporate peanut butter is a good thing for everybody. By virtue of a blog's blogginess, it lives in a different world than a simple newsfeed does, and not treating it like it does or like the blogger is on the payroll to serve some specific corporate agenda is what keeps a blog authentic and relevant and subscribed to. People read The Beat because they want to read Heidi MacDonald and not because they necessarily care about the rest of Publisher's Weekly.
and what's that got to do with anything?

SOME?! How about all of them?
We could even pack a few climatologists on board to tell them that their new moon home is getting warmer.
Not being big on science, this may be a stupid question, but how do they know it's methane and not water? And if it is methane, would it be possible for us to harvest it in the future? How about use it to power and control a human friendly environment to support a colony?
Well one way is because the temperature. Water cannot exist as a liquid under 0 degrees Celsius. As for methane, the dark spots correlating to pools of methane would make sense, for when the planetary object is thermally induced by the sun, it may be enough to cause methane to evaporate into its gaseous state.
That makes sense. Thanks for the explanation Nick.
Wrong. Water can remain liquid below 0 degrees celsius at different pressures and purity levels.
Also the refraction of the light through the atmosphere. An atmosphere with suspended water will refract light differently than an atmosphere with suspended methane.
Harvesting the methane would probably prove inefficient. It would certainly be so at our current technology level.

Really cool discussion. From the moons of Saturn to farts. Gotta love it.
Check with Andy of Eureka. He's been there.
And for some reason, the writers didn't finish that storyline. This sucks!
Nicely done! Sounds like a nicely place to sit and read a book. Very nicely sounding place.
The fact that hydrocarbons exist on other bodies in the solar system seems to strengthen abiotic oil theory, although there is minimal proof of that on earth. Although abiotic oil is a valid scientific theory, it is mainly doubted, but is an interesting topic to investigate.
I agree with the abiotic theory because there is no evidence of surface life forms that could creat a methane atmosphere; so subsurface biotic activity would be a good conclusion.

What? Are you sitting there with thesaurus/encyclopedia and pretending to be smart? "Abiotic" oil theory? That died 100 years ago and nobody cares about it now.
Fine. Then by now (it's been a hundred years, after all) you know how methane is created on frozen moons (frozen dinosaurs?.) Please learn us troglodytes up, kay?
This article inspires me! Maybe we could sent a shoe to explore Uranus! Maybe there would be a tropical or maybe only a sub tropical methane lake.
Sorry!
ok,,so we as a race can't get there now,,not anytime in the near future,,or even our life times,,,but,,it is interesting to know.anyone out there ever hear of helium 3?contact me at bthree6@yahoo.co.uk if you have,,,thanks
Well not you Americans, you're too poor.
aren't we scientists an odd bunch, "tropical" heh by what standard venus?
The word "tropic" describes a band on the planet near the equator where the sun (or star it is orbiting) is directly overhead at some point during the planet's yearly orbit. It is warm relative to other points on the planet's surface.
Yeah! Because the universe shouldn't contain any form of humor at all!
So how come if there is life in a methane lake on a moon with a methane atmosphere, if I buy an incandescent light bulb we are all gonna die? Or if a farmer's cow passes its methane?
Do little green men swim in them?
Methane? Isn't that a "fossil fuel" according to greenies? Then, life must have existed there for there to be fossil fuel! Ether that or maybe calling natural gas a "fossil fuel" is a mistake.
Pretty sure you're incorrect on that assessment. In more ways than one.
Wow. That's not what it means at all.
we've had this conversation berofe do landfills produce more methane than composting? Is keeping yard waste separate from other trash a smart move, or should we throw it all in
Well, I wouldn't call my farts a fossil fuel.
Methane isn't a fossil fuel, it's a natural gas.
I'm gonna assume here you aren't a scientist.
I'm going to assume that your conjecture is: only a scientist can understand nature?
Methane is created in a cows gut when it digests ORGANIC materials, like grass.... Landfills moniter the air for methane and they have methane wells to flare the methane gas off......again organic material being digested by bacteria........so what does that mean, means God has created some really cool stuff.
Actually, methane can be created by more than 1 process, some of which don't necessarily entail an organism making it. The presence of methane doesn't necessarily mean life once existed on that planet.
0_0 HA! Citation needed.
New avatar, Bill? Playing the other side now?
now you got it all. Good job Bill!
And just in time for my vacation. A week at the lake is just what I need.
DJ, While he did make an ignorant statement the methane is essentially useless as a fuel source. It would simple be far too expensive to be practical. Methane is cheap and easily found on the Earth. Trying to get it from Triton would cost trillions of dollars in lift capacity, infrastructure, and so forth. Outside of the realm of science fiction it's just a non-starter in terms of exploitation.
Typical ignorant thinking! Way to interject politics into this really cool science article. Just doing your job I guess, steering the story down the paths your bosses tell you to?
... and smelled methane.
very original. Can we send all the religious nuts and politicians there with people like you that still believe one party is better then another...
Methane Lake? So, it's the Bog of Eternal Stench.
1000 internets to you sir.
Methane gas is odorless.
ARTAX!!!!!!!
Very cool – I love hearing about this stuff.
The planet supposedly consists of ice and rock with liquid methane lakes. Large ice mountains with liquid methane lakes and rivers.
Must be spectacular.
This is a big deal? Read Genesis and you will find the term "waters above the firmament." This means water beyond.......
The fact "science" will not tell you is that in order to keep the degree Kelvin steady throughout the universe you have water to keep the universe cool enough. SO IT WILL NOT BLOWUP.
It is unfortunate that you do not seem to understand much about astronomy and astrophysics and the nature of the universe. Your statement about water and the temperature of the universe is incoherent.
I suggest you do some study of astronomy. I suggest "Sky and Telescope" and "Astronomy" magazines as an excellent source of knowledge...
His science may be weak but his knowledge of Scripture is spot on. Genesis clearly tells us that water was everywhere in the universe so we are not surprised that there is or may be water on other planets. No matter what we find we will surely always be astonished at how precise the Bible is which only points to the Creator and makes this nonsense about evolution laughable!
Uh, Joe, liquid methane is NOT the same thing as water. HUGE difference between the two.
Lol.. so because the bible says water is everywhere.. and water IS everywhere in the universe, suddenly that's proof that the bible God exists? How about, there's iron all over the universe.. there's hydrogen all over the universe.. there's nitrogen all over the universe.. Mind you, back then people thought the universe was our solar system. Even in modern times, people thought the universe was the Milky Way. And the part where he states that water is needed to KEEP the universe cool so it doesn't explode? Holy cow.. I don't even know where to begin on this..
Yes, science is not your strong suit.
Please, say no to crack.
Silly person. Waters above the firmament was the way the primitive Hebrews tried to explain where rain came from since they were not aware of the process of evaporation and the rain cycle. It is never a good idea to derive your facts from a fairy tale.
Look who's silly. Read the Bible and you will find that evaporation was already explained. You just don't know what you are talking about. See the book of Job which is loaded with scientific facts that could only have been explained Supernaturally. My money is on Biblical Theology. Naturalistic science is limited in its understanding as it ignores the supernatural. And that's just sad considering that the Bible is largely responsible for the enlightenment of men's minds.
Evolution is a fool's game. Things cannot create themselves. Living beings cannot give themselves life. Get with it folks and stop this fairy tale nonsense that ignores a supernatural Creator.
The level of brain wash is astounding. I'm happy I left religion years ago, after questioning inconsistencies and applying what the universe designed my brain to be.. logical.
Joe I am sure Biblical Theologians will be happy to take your money. Bible people are particularity good at that part.
LOL, if anyone is buying into fairytales here, it would be Mr Joe!
Joe, what are people like you going to do when life is discovered (even if it is only microbial) on another planet?
News flash folks... and this pertains to both sides. Disparaging remarks towards people's beliefs do not make them "wake up" or suddenlyl go "yeah... I guess you're right, it must be a fairy tale, I must be brainwashed". It simply puts people on the defensive and the whole point of the conversation gets lost because people's sole focus is now on what was said and how it was said. Try going into a forum where being gay is the topic and frame your opinion using belittling adjectives and see where that gets you... or a political forum... or any type of forum for that matter. We all know the old saying about opinions, and we do have freedom of speech, but someone's point of view stated in any way that people can perceive as an attack on their character is just going to tarnish the point. If I say I believe in God and then get 5 replies saying I'm brainwashed and believing a fairy tale... trust me... I'm just gonna write you off as a bully and a jerk. I'm going to completely ignore your view and maybe make things worse by saying something offensive back to you (and again, I say this to both sides of the discussion). OK, so I believe what I believe and I'm a total stranger to you... what on Earth is the point of trying to convince me otherwise anyway? You'll never hear from me again. Nonetheless, even if I assume you are trying to come from a good place and help me out in life by not following a pipe dream, there has to be a better way to get through to me without insulting me and vice versa... Unless you really don't care and are just trying to be funny or you're just really bitter about the whole subject and are lashing out... It still accomplishes very little.
And we wonder why Americans are so scientifically illiterate....
False premise. Enjoy your American Internet, iGadget, computer, OS, Hubble views and military defense.....and kindly respect the country that drives progress world wide.
You know that feeling you have when you hear Pakistanis talking about how they're supposed to martyr themselves and in return they get a gaggle of virgins?
That's what we sane people feel towards you right now.
I laughed so hard at this, I think I caused a methane leak.
You're confusing religion and science. Scripture was never written to be scientifically accurate in a modern sense. It was written as parables to convey universal truths in a story form. When modern believers try to fit scripture into their limited modern sensibilities, they confuse the intent of the writings. To attempt to draw literal or "factual" evidence from scripture is a mistake and in some cases borders on heresy. Don't miss the forest for the trees.
Nonsense Seth. You are compartmentalizing things. Religion and science can be used together to explain the things God created and how He made things to work. Scripture is scientifically accurate. Isaiah 40:22.
Joe: The verse you linked states: "It is he that sitteth upon the vault of the earth and the inhabitants thereof are as grasshoppers, that stretcheth out the heavens as a curtain and spreadeth them out as a tent to dwell in." Like I said, it's a metaphorical, poetic story that can be true without being scientific. God sits above the earth and stretches out the heavens as a tent above, an obvious metaphor that the entire world is God's tabernacle.
I'm still baffled as to how God has male genitals.
Joe: That verse is actually a good point. If you use the translation of "ḥūḡ" to mean "circle," and then say that the verse "proves" that the ancient Israelites believed the world was a sphere, you miss the whole point. The point is that God sits above the earth and spreads out the heavens like a tent, or dwelling, or a holy tabernacle. You can't pitch a tent on a sphere, so then you lose the entire point of the poem. The point is to picture a flat plane with all the people of the world as grasshoppers and the sky and stars above like the canvas of a tent that God set up for us to dwell in and worship in. You want to trade that beautiful and spiritual imagery for a cold, meaningless "proof" that the Bible said the earth was round? What do you gain by doing that except some points for Team Christian? You lose all the meaning and truth of scripture when you try and shape it to be a textbook. The Bible doesn't teach Truth through science. It teaches it on a different plane, through spiritual imagery, poetry and mystery. It can be True without being factual.
ironfray: haha God doesn't have genitals. The idea of God as male is just that it's a paternal, fatherly type of representation. Culturally in the ancient world, tribes were related by blood and led by a fatherly figure. So by being male, God represented being a leader, a progenitor, and the person who created us (but interestingly, didn't bear us - the earth did, as God formed man from the earth). God as Heavenly Father is full of imagery since everyone has a father (though that isn't always the healthy relationship it should be).
I imagine "science" and the "Creator" will meet in the middle at some point. I think F. Capra (physicist) said, at (~) science is "out-dimensioned" at some point – at which point – it must be recognized that there is a Supreme Being/Intelligence. I'm also into the abiotic theory of so called "fossil fuels" – how in the world would a mass grave of anything produce such a soup, whereas, tectonic friction might wring the liquid from the sponge.
Sir, the text you're referring to describes the Chevy Nova, not a Stellar Nova.
Except that's not what it means. The firmament separating the waters above from the waters below is the sky separating the rain waters from the ground waters. We now KNOW that rian doesn't come from "above the sky". We know that both rain and ground water participate in the great Water Cycle.
And besides, it was never, EVER, supposed to mean "water in space". That's just dumb.
The Law of Entropy is proof that God exist, you don't need a bible to tell you that.
Interesting!
You are right. Speculation is not science. So much of what passes as science these days is just that. BTW, you're sarcasm was unfounded.
All science is speculation. That's how it starts: Question, Hypothesis, Theory, Law. Without speculation there can BE no science.
Unless you're a AGW scientist. Then it's: Theory, Law, The science is settled!
To those saying that life can't live in those conditions: there are microbes on Earth that live in sulfuric acid. There is life deep in the ocean that can live at ridiculous temperatures. Life can exist in much stranger environments...it doesn't always need oxygen and nitrogen to live.
As Dr. Ian Malcolm once said: "Life will find a way."
Actually, I think to further your point, I think I remember watching something about crustacean like organisms living solely in and around methane vents in the ocean. I could be way off on that though, it's been a while.
I rellay like your web site.. rellay wonderful hues & theme. Did you create this internet site yourself? Plz reply back again as I’m looking to create my own website and would like to know wheere u acquired this from. many thanks
I cant wait for us to set foot on this foreign land, conquer it, exploit it, and eat its inhabitants.
Hmmm... tastes like chicken.
No.. we'll just go there, make crop circles then leave.
And give those microbes evidence that we big various-shades-of-brown men from Earth exist? Not on your life!
True.. we don't want those microbes mounting an offensive on Earth. They're so tiny, we won't know they're here till things start randomly blowing up.
samuel cordrey the whole point of lietrby is that people are allowed to do things that you find offensive (e.g. dancing at a memorial) and you can do things that other people find offensive (e.g. practice your religion / abortion / smoking).When the state mandates what you may and may not do via legislation that is called tyranny.Did the supreme court not rule that those religious zealots who protest at the funerals of soldiers killed in Iraq/Afghanistan are ALLOWED to protest at those funerals?Yes you may not like it, it may not be morally' or ethically' right' either, but the question is do you want to live in a country where the STATE can mandate whether your behaviour is acceptable'?If you do then ask yourself 150 years ago when you were black and the STATE deemed YOU.. just by being black' were unacceptable' or 70 years ago.. when the state deemed Jews/ Gypsies and Gays' as being unacceptable' and subject to being removed from the planet.
Methane? Could it be that this moon has a lot of cows on it? Can't imagine going there, as it would be like living in the midst of a giant fart.
LMAO!!!
Methane is a colorless ordorless gas. Try again, this time put some science in your humor.
Early mornings without coffee makes me cranky too Butchie.
Wait, aren't farts just methane gas? So you're telling me there might be some bacteria living in a lake of liquid fart? Sure, sounds plausible.
Gas can contain methane. If it does, it will likely be smelly, indicating an unhealthy gut that is not breaking down food completely.
Most gas is simply air that has been swallowed and passes through the digestive track.
Methane has no smell. The fart smell is added so that gas leaks are easily detected (from pipes).
Wrong
Ha, I see what you did there. L, do a little reading on the "propane" smell. And set your Satire Filter down about 2 notches.
Actually this is RIGHT. Methane is a colorless and odorless gas. Like Natural gas, an odor is added in order to detect leaks.
I have a question here, If the planet is made of methane and we land a ship there, what is to say a spark from a switch doesnt take out the whole moon? it is methane no?
Read the blog. No Oxygen = no fire!
and it would really suck if those organisms produced oxygen (photosynthesis). Boom!
You would need a whole lot of Oxygen for that to happen my friend. And I mean a lLOT!
There was a time before photosynthesis that the earth had no oxygen either. But, I'm betting there is none on this moon becuase if there were, sometime over the last billion years or so something would have created a spark.and turned the thing into a meteor shower.
without the presence of at least a little oxygen, ignition can't occur at all. But you are thinking in the right direction..
It is thought that this process on earth was the first life-produced natural disaster. Not that there was an explosion, but as photosynthesis (slowly) began introducing oxygen into the methane-rich environment, the methane was oxidized over millennia until there was essentially none left. Organisms that needed methane and could not tolerate highly reactive oxygen became extinct, and life as we presently know it took hold.
all by itself?
Methane is odorless. The smell you associate with farts and natural gas is low concentrations of sulfur compounds. Tert-butyl thiol is used to give natural gas the odor you are familiar with.
Democracy is secondary to civil rights. Unless of course you also support slavery and denying women the right to vote. Being from TX it wouldn’t surprise me.
It would smell like farts if you could live long enough after breathing it to have an opinion.
Another CNN article that fails to provide minimal information that people need. We know Tropical as referring to an area on earth 20 or so degrees N and S of the equator where the temperature in comparatively hot. Therefore it would be nice to mention the surface temperature of Saturn in the "tropical" zone for the sake of comparison.
All this requires is an email address.
Congratulations. You qualify for a CNN job.
ROFL! Derp!
Musta been a whale of lot of really big dinosaurs to generate that much methane... fossil fuel .. right?
Why do we need it? They were providing information that heretofore was unknown to most. These articles are meant to be informative but when you are talking about a moon that is over 9 AU in distance from the sun, it is hard to know everything.
Unless the state of education in this country is even worse than I thought, most people will know that if liquid methane is present, it's going to be a lot colder than what we would consider "tropical", of course the quotes around tropical, and the mention that it's not fit for humans to swim in might also be a clue. I don't think listing the temperature (if it's known with enough precision anyhow) is necessary.
I think that CNN meant "Ecuator" instead of "Tropical"... Or maybe they know somthing that we dont!
Hello, JS & Jupiter,
In this instance "tropical" refers to two specific lines of latitude - that is, 20 degrees North and 20 degrees South on Titan - and not so much the temperature. Though, Titan's equator is located in the moon's tropics. I hope this clears things up!
Thanks so much for reading,
Sophia Dengo, CNN.com
Yes... they are tropical lakes. As in, centered around the tropics. As far as it being cold... Could simply be the air pressure that causes the gas to be in liquid form and not the temperature.
There is nothing "tropical" about -260 F. Someday we will be able to take a "tour" to the moons of Saturn via Virgin Galactic. I’m 37 now so hopefully I’ll' still be alive... I hope 😉
well, compared to -400F, -260F is decidedly warmer!
lol good one
Honey, a new tropical paradise! I'm on it Dear! I see that Priceline has the cheapest rates – I'll book us a trip on Dragon 9.
...with Shatner, still doing the commercials. ;P
Oh I forgot to mention, that since oil and methane are fossil fuels there must have been dinsaurs there, then again perhaps they are not fossil fuels Hmmmm
Fossil fuels came from the fossil remains of dead plants, not dinosaurs.
Has that been proven?
Yes, I'm reasonably sure that the plants (and animals) that were responsible for our fossil fuels are currently dead.
Methane is a very simple hydrocarbon (CH3) that can be produced through multiple methods which do not require the presence of life. So the presence of large amounts of methane are not necessarily indicators of life.
Liquid methane and methane rain, -161 degrees C, just right for a microbe or a swim, yeah right.
Much as I'd like to agree, he's got a good (if odd) point.
"Honey? These fish sticks taste sort of methaney. Where did you get them?"
At a jazz festival where Pat was playing.
10 internets to you for the jazz reference
liquid methane, an atomshpere...and no meteor or asdroid that came into contact with the moon? amazing, bet when we try to land there the moon will explode. I can understand that the gravitation from Jupiter has a part to play, but not likely? even small debris entering the atmosphere can ignite the fumes. this is all fantasy or best guesses, until we go there, it will remain fantasy. or it isn't methane? like I said, until we go there, we don't know? hard facts, we don't have much of, only speculation.
Methane is flammable only in the presence of oxygen, and only in a very specific concentration (5-15%) of gas to air. If those conditions aren't met, it won't ignite from any source, be it a meteorite or a space craft.
Maybe you shoud look up the Cassini and Huygens missions. We've landed there.
Jupiter is mostly hydrogen but it doesn't explode because there is no oxygen. To get a fire, you need Oxygen, or in some cases, chlorine.
You meant Saturn right?
Look up the Cassini-Hyugens mission. We've already landed a probe there. It's around Saturn. And what everyone else has already told you about the necessary conditions to cause an ignition.
I'm glad you're musing, but better than posting to a random forum would be to actually do some research about the subject. Self-education is possible and very rewarding and would have answered all these questions.
Spell check is a wonderful invention
So where is the spell check in the reply box? Funny, I don't see it. I guess I should type all my replies in Microsoft word, spell check them and then copy and paste. Yeah. I'm sure that's what you do right?
COULD harbor tiny organisms. And I could win the Powerball jackpot. But I certainly wouldn't call it news unless I did.
The news is the lakes existing in the tropical zone of the moon. Nature has a very high rejection rate, so I'd argue that really anything published in it is "news", at least for the scientific community.
Moot and near impossible to prove. Articles like these are published to keep public interest in programs that are a painful waste of taxpayer money. Once some real data or facts are discovered, please publish them. But this near hourly speculation on what might be on a moon we will never see has become inteligence insulting cliche. Feed the people of Earth first. Then worry about the microbes on a moon.
Man, they just can't anything by you, can they?
nope not true
Did you actually read the Nature article? This is a peer-reviewed journal, you can't just submit any crap article to it and expect it to get publish.
Your entire response is perplexing. First you complain about wasting taxpayer money, then you demand that only undeniable facts be published – which is it? You need funding for the research that you're whining about. Then you go on to comment about feeding people on Earth before we look at other planets and moons, yet that has been an ongoing science for centuries before food and water shortage became such a widespread issue. You want a solution? Prevent people from procreating, THAT is the real problem here. If people would just wake up and realize that we're overextending our resources, maybe then they would think twice before rubbing their genitals against one another.
Nothing wrong with rubbing genitals together, just don't plant the seeds in the soil. It's funny to read some peoples comments about how wasteful these programs are and how we should feed the world with it instead.. I hope they realize that funding for these types of programs won't feed anyone for very long. Might as well use it to peak into the universe and set ourselves up for the long haul when this planet is bursting at the seams.
feed the people-let them feed themselves--in the end the only hope for mankind is space exploration--but u seriously would rather feed some people than teach them to feed themselves--and u probably think millions will die from climate change-is there help for those who would push the boundries or do we go the other way it used to be and be primal-tribal and then there is always someone else to eat
wow this stuff is co cool
I Love FANTASY – When I was in Grade School 50 Years ago – There was a 'science' book in the School Library that suggested (with pictures no less) that VENUS might have 'Tropical Jungles' and DINOSAURS (cool) and the BARSOOM of fiction or the Martian Canals of Early Telescope Viewers IMAGINATION are more FUN than LIFELESS ROCKS – but That's what they are. Its nice to IMAGINE fantastic worlds but I will prefer when we actually go there and see.
I can't imagine a methane lake is something that would be very much fun to visit. And this isn't fantasy, 50 years ago there were no probes collecting data... you want fantasy in school, go down the hall to where the creationists are trying to get their programs taught in class.
Wow! Where does that hostility come from?
Someone here lacks imagination and is angry at anyone else that has some. I won't say who though.
haha sadly the creationists are doing the rest of us christians a real disservice. They have such little faith that something like evolution shakes their entire world view. It's sad that few modern christians can understand that something like scripture can be true without it being factual. If it could be proved, what is the point of faith? If it's literal then where is the mystery of it?
Spiritual texts should not be treated like textbooks. It cheapens them and makes them confusing. They should be treated like poetry and song, something to be studied and thought about, not sourced like an encyclopedia.
I think I saw this on wonders of the universe, or just "the universe". Why is this news now?
Brian Cox covered this a year or two ago on "Wonders of the Universe"
Because you'd be surprised at how many people don't watch any of those programs and are unaware that his is old news.
Way COOL!!!
Literally since its temperature is around 100 K.
Why can't humans swim in methane lakes? Or why do we absolutely need water instead of other substances?
Miguel, aside from the possible toxic effects, understand that , in order for Methane to be in a liquid state, the temperature has to be quite low (about -200 C) so, no, it would not be a long swim, :).
wow thats cool
polar bear plunge! Reminds me of a Futurama episode where some that alien news guy was covering such an event on Pluto I think. He finished with, "There were no survivors."
Outside of the fact that methane has to be around -260 degrees F to become liquid (you know methane as "natural gas"), please take as many laps as you please.
It's too cold. However, an organism could have developed in that environment which could in fact swim in it (in which case liquid water would be considered extremely hot to them... sort of like how we think of liquid iron).
wow thanks i love this stuff
humans developed in a water based environment. any dramatic changes in chemical composition would likely be toxic.
@ only gods children- I really hope you're joking. That's far from factual. The earth is billions of years old and humans evolved just like every other living creature on the planet, thats a fact.
@ Only God's Children! You know, it is entirely possible that people dont believe in what you think. Oh, its also entirely possible that factual evidence can outway spiritual belief for some people. You can't expect everyone to believe the way you do simply because a book thats only been around for little under 4000 years says so. Historical, Scientific, and in some circles Spiritual evidence shows the world to be older than 6000 years old. Did you ever stop to think that it could be entirely possible that the theorys of evolution and the theorys of Creationism could correlate? Only God knows how long a day in his life is. A day for God could be a day for us or 100000 years for us... we dont know. Whats to say that God didnt create "life" by starting small (bacteria) and then allowing it to process itself out to what we are today. The fact is that we dont just "magically" adapt to surroundings and life around us, it takes years for our bodies to adapt to major changes to enviroment and stimulus. If God really had a hand in it, dont you think that we could adapt to cancer and poison in a 5 second time frame? In other words, don't attempt to preach something and expect people around you to accept it as the "ultimate truth." People believe based on various aspects of their personal self. Not because some person on the internet told them that "only God made us."
Guy's, I'm pretty sure he was joking about god creating man. Relax.
Methane isn't a solvent. Solvency is an important part of organic chemistry.
That's a very Earth-centric position. While I agree it's unlikely, it could be possible. Nothing as complex as fish, but maybe some self replicating molecules. Who knows, always worth a look.
Assuming you could wear a space suit to keep you warm, the density of liquid methane is about 0.42 g/cm^3. The density of water is 1.0 g/cm^3, and humans are about the same. Humans are too dense and if you tried to swim you would sink then freeze.
You wouldn't freeze, you still would have on your spacesuit. Also, you would not sink either, as you would fire your boot rockets and maintain spacial equalibrium with the surface of the methane, resupplying your fuel from the liquid around you and converting the heat into thermal energy to break the gaseous molecules above the methane into O2, for breathing and as a oxidizer for the boot fuel.
@ Peter Evans That is an awesome idea... patent it, I expect the design specs on my desk in the morning. Let the refueling space suit with rocket boots building begin!
Look . . . if you are going to give me panic attacks about chemistry could you at least wait until I've had a cup of coffee!
🙂
"Humans are too dense"
Sir, you have indeed said a mouthful there.
When we building a pipeline?
Cool!
