Space 101

SleepyHappyDoc writes "The European Space Agency has announced that a mysterious radio wave may indicate the existence of a hidden ocean underneath the surface of Titan. The Cassini-Huygens spaceprobe, which entered Titan's atmosphere over two years ago, collected evidence and information which has led to this potential discovery. This technology may lead to entirely new ways of finding out information about other planets."

But it's *beneath* the surface of Titan. Not much opportunity for surfing there.

However, if you wanted to surf the methane seas of Titan [nasa.gov] , that appears somewhat possible, though you'd need an extraordinarily well-insulted suit, and, if I recall correctly, you'd need some kind of floatation device because methane is much less dense than water (you'd sink to the bottom like a rock). Plus the whole breathing thing, I suppose.

Actually there is liquid methane and frozen water..
Since the planet's temperature is around 179 C, the water is rock solid and the methane is in liquid state like what water is to us.

Curiously, when the first pictures of Titan's surface appeared, they showed a earth-like surface, with rivers of methane similar to our rivers of water.

"Mysterious wave" (5, Interesting)

N7DR (536428) | more than 7 years ago | (#19387717)

The European Space Agency has announced that a mysterious radio wave...

And there's no point in reading TFA in order to try to remove any of the mystery. Frequency? Duration? Periodicity/repeatability? Any characteristics whatsoever? Not a single useful property is mentioned in the article. In fact, apparently it's not even certain that it's not an artifact.

Actually, the whole thing is a rather weird: not only do they not give any details whatsoever, but I find it difficult to countenance that a scientist would talk about a "radio wave" rather than a "signal" or "emission" in this context. Speaking from my background as a co-investigator on the Planetary Radio Astronomy experiment on Voyager, the word "wave" is usually reserved for theoretical treatments in published papers.

Anyway, I guess we just have to wait for the upcoming issue of "Planetary and Space Science" to see what the article is really talking about.

Re:"Mysterious wave" (1)

ve3oat (884827) | more than 7 years ago | (#19392301)

Yes, TFA is not helpful. Use of the phrase "a radio wave" implies a monochromatic emission, perhaps even a coherent emission. On earth, the Schumann resonance emissions (caused by the sum total of radio energy from lightning strikes) is a broad peak in background radio emissions around 8 kHz. But this peak is definitely not coherent, nor on a single frequency, nor even narrow-band. Whoever wrote the article clearly didn't understand the phenomenon they were trying to describe.

Re:"Mysterious wave" (1)

Muad'Dave (255648) | more than 7 years ago | (#19400379)

Aren't the Schumann resonances centered more near 20 Hz (yes, Hertz. Not kHz)? Generally the frequencies are listed as 7.8, 13.8, 19.7, 25.7 and 31.7 Hz. They are true resonances, and don't seem to be a broad spectrum.

See this excellent VLF/ELF site [www.vlf.it] for more info regarding the world below 100kHz.

Re:"Mysterious wave" (1)

ve3oat (884827) | more than 7 years ago | (#19404081)

Hertz! Yes, of course. (Sorry, I deal everyday in kHz and my fingers are programmed to type it.)

The listed frequencies of 7.8, 13.8 etc Hz are only averages. The resonant frequency varies with time and place according to the height of the ionosphere at that location and time of day and season, as well as along the radio path to the location of the dominant lightning energy sources. During the day the bottom of the ionosphere (D-region at ELF) is 60 km and during the night closer to 90 km. This forms the upper boundary of the earth-ionosphere waveguide alluded to in the original article. So, in practice, the "resonance" is broad, being the sum of all contributing resonances (I have listened to it) and is not a pure, single frequency as one might imagine.

How long 'till proof of life? (3, Insightful)

Leontes (653331) | more than 7 years ago | (#19387787)

Ok. We have many extra-solar planets. We've got water on mars. We've got an ocean on titan. We've got massive amounts of funding on SETI. We had that SETI at home running for years... Despite that now-pretty-much-debunked mars metorite... When is that we will find believable proof of extraterra life? I'm convinced life has to be out there. When we will find it? I doubt we will find it anytime soon. We aren't spending enough money and we aren't capable of leaving this island world of ours. Intelligent life that we can communicate with or interact with in a meaningful? Highly unlikely. The universe is just too damn big and the chances of intelligence development too small. We may have found an ocean on titan: I really wish the task of finding extraterresterial life wasn't so minimal.

voislav98 (1004117) | more than 7 years ago | (#19388205)

You have to remember that the results we're getting now (Cassini, Mars rover) is from probes based on the technology developed mid-80's to early 90's. The next generation of probes, based on 21st century technology, will be able to look for life but most of them won't start returning data until something like 2015. So my guess would be that we'll be seeing some results about then.

The answer is in genesis (4, Insightful)

oni (41625) | more than 7 years ago | (#19388361)

No, not *that* genesis (but I made you look, didn't I). The answer to the question, "why haven't we found life yet" really lies in the fact that what actually gets life going is still quite a mystery. As you know, scientists can simulate the conditions of early Earth and they can produce amino acids, but they can't produce DNA or simple cellular life.

My point is, we may still be missing something important and fundamental. That's what makes science so interesting. There is always something else to discover.

In Dawkins' book, The Blind Watchmaker, he makes reference to the work of another biologist whose name escapes me at the moment. But that guy's theory is that silicate crystals in soft clay are the necessary to get early life going. The theory goes like this: imagine a river with clay at the bottom. The clay forms microscopic crystals, which sometimes catch and constrain amino acids and other building blocks, like stuff getting stuck in the strainer in your sink.

As the crystals grow, they sometimes "empty the strainer" basically spitting out these now larger strands of amino acids. The strands and structures flow further down the river and inevitably get stuck in another crystal. There they grow larger and eventually get spit out. The process repeats all the way down the river.

At the mouth of the river, you've got billions of different pre-biotic experiments washing out into the sea. Just by chance, one of those experiments is able to reproduce itself. Life is unstoppable at that point.

So what I'm getting at is this: we keep finding *some* of the building blocks, but we aren't finding them arranged the correct way. A static sea (maybe even with hydrothermal vents) on Titan or Europa or Mars may be able to support current Earth life, but it may not be able to spark that all-important genesis event.

On the other hand, early Mars may have been perfect for this.

Perhaps the level of intelligent life out there considers us to be about as intelligent as we consider amoeba's? At this time, just discovering LIFE even if it's a bacteria would be significant. Don't give up on SETI there are new signals coming in all the time that need analysis. Remember we've only been producing electomagnetic signals that could leave Earth for less than 100yrs. If Civilization X got one of our early radio broadcasts which would be incredible in and of itself as weak as the signal would be, they would have to send a reply back (assuming they understand radio) which would take as long to get to Earth as our signal took to get to them. Perhaps they started broadcasting 50 yrs ago in an attempt to find us, we could get that signal any time.

Not everything is in a red shift. Blue shift objects are moving towards us, catching up to us.

With that being said, your argument is valid, but only for x^x years, until the blue shift catches up to the x^x number of years we've been broadcasting. Not in our lifetime certainly, but maybe before the sun goes red...

Few people want to admit this, but I'm pretty much convinced that we're alone in the galaxy, primarily because of the Fermi Paradox [wikipedia.org] . Specifically, the argument that it takes a "relatively" short time (on galactic scales) for a space-faring civilization to fill up a galaxy, even at sublight speeds, when you factor in geometric progression. If intelligent life was common, one would've filled up the galaxy by now and we wouldn't even exist.

After all, we haven't managed a colony on our own moon yet, much less on other planets or planets in other solar systems. Why would you assume that other forms of life would be that much more advanaced than us?

Er, why would you assume that? The earth is 4.5 billion years old. The galaxy is 13 billion years old. It take about 5 million years (give or take) to fill up a galaxy. Five million years is nothing in the scheme of things.

After all, we haven't managed a colony on our own moon yet, much less on other planets or planets in other solar systems.

We've gone from stone tablets to space travel in five thousand years. Five thousand! That's a tiny interval when we're talking about galactic time. The odds that two civilizations would develop technology at exactly the same rate and be at the same level at the same time is incredibly small.

You're assuming that alien life would want to cover the galaxy. Perhaps the sane choice of any evolved civilization is population control?

And another thing... someone must be the first civilization capable (and willing) to spend thousands of years expanding to other star systems. Perhaps we were born to early? Perhaps we will be the first?

It only takes one civilization. They're ALL uninterested in expansion, across billions of years? Also, even if they want to do population control, that doesn't preclude sending out AI self-replicating probes. But where are they?

Perhaps we will be the first?

That's another way of saying we're alone in the galaxy.

Actually, I believe the funding for SETI is minute as is the total amount of time they have actually been listening (given they have to beg, borrow and steal facility time) and the amount of sky covered. The idea that "we should have found something by now" really only holds true if they were scanning the entire sky 24-7 with adequate funding - but none of that is happening with SETI.

I'd ask if I could download a sample of this, but quickly realized the rights to the music may belong to some kind of quasi-sentient lawyer-being or, worse yet, a RIAA radio station/satellite launched into the moon just to catch me.

>On Earth, radio waves occur naturally during lightning strikes, which cause electrons in the atmosphere to oscillate and release the waves. These radio waves bounce back and forth between the Earth's surface and its ionosphere, the high-up region of the atmosphere filled with electrically-charged particles.

I do this myself on earth a lot. It's lot of fun to experiment.

In the past month, I was able to bounce a radio wave of approximately 20 meters to 40 meters in length from California to Hawaii [wa5znu.org] , Mexico [wa5znu.org] , Australia [wa5znu.org] , the Bering Sea [wa5znu.org] , Pacific Islands [wa5znu.org] , Vladivostok [wa5znu.org] , Khabarosk [wa5znu.org] (Russia 20km from Chinese border, where they had the chemical spill [google.com] a couple of years ago), and South Africa [wa5znu.org] .

Some of this was with off-on keying of an RF carrier, and some with digital-signal processing software running on Linux (both extremely weak signal [pe2pe.eu] modes originally designed for bouncing signals off the Moon, and more conversational [wa5znu.org] modes.)

"The results would also be unusual because Titan's dusty surface makes a poor reflector of radio waves"

A potential problem, especially if they were scanning the lower frequencies, is the probable contamination by Saturn's scattered light

wait... (5, Insightful)

jcgam69 (994690) | more than 7 years ago | (#19388123)

The next step for the researchers is to determine if the signal detected was the result of an error in the probe.
Shouldn't you do that first before making a major announcement to the world press??

surgeon (61206) | more than 7 years ago | (#19388311)

Using planets or satellites for calibrating astronomical observations requires taking into account their spectral dependence, and bears intrinsic uncertainties. For all solar-system objects, one has to take into account the phase effect, and possible spatial variability over the instruments due to surface morphology or climatology. ..and in the case of Callisto and Titan respectively, the possible scattered light from Jupiter and Saturn.

"Good day, gentlemen. This is a pre-recorded briefing made prior to your departure, and which for security reasons of the highest importance has been known onboard during the mission only by your HAL 9000 computer. Now that you are in Jupiter's space and the entire crew is revived, it can be told to you. 18 months ago, the first evidence of intelligent life off the Earth was discovered. It was buried 40 feet below the lunar surface, near the crater Tycho. Except for a single very powerful radio emission, aimed at Jupiter, the four million year old black monolith has remained completely inert, its origin and purpose still a total mystery."
