Sea of oil seen on Titan/DS1 Asteriod fly-by

nsanch writes "The BBC is reporting that there may be an ocean of oil on Titan, the only open sea on a planet (other than Earth) that's in our solar system." And in other news, thanks to Corrado for the pointer over to the Deep Space 1 Mission Log, chuck-full of details from the recent Asteriod Braille fly-by. Amazing how much info you can get at 35,000 Miles per Hour.

  1. Methane and ethane are not "oil" by Anonymous Coward · · Score: 2

    All oils are hydrocarbons, however, not all hydrocarbons are oils. This fact is lost on the media who were quick to happily substitute one for the other and log another notch on their sensationalism gun.

    Most earth oil deposits are formed from decomposed plant and other biologocal matter. Taking the wrong assumption that HCs == oil and that oil came from life leads one to a totally bogus conclusion.

    Titan is an interesting collection of chemicals, but is of zero intrest for possible life. You'd be better off looking for microbes on Mars near the poles or in the more plausible slushy ice water oceans on Europa. (Despite Europa's distance from the sun, Jupiter emits significant heat at close range which is leftover primordial heat from the solar system formation).

      Sometime back a few years, 1976 as I recall, there was a National Geographic discussing the possibility of life on Jupiter. It makes perfect sense, when you think about it, as a planet of that size would have a thick layer capable of supporting life.

      One of the probes (Voyager 2?) we sent out apparently returned information to the effect that the giant red eye of Jupiter was in fact largely composed of amino acids. If there are amino acids, then there is the possibility for more complex forms of existence.

      Personally, I believe that life originated in the incubation-like atmosphere of comets, and that microbacteria in the comets made it to earth. (Some terran straph/strep bacteria is currently on the moon, surviving, as I recall from one of the NASA reports, but I can't remember which.) It is likely then, that any place in this solar system where life could survive, it has, and will. That's what life does best. (Up to the point where it reaches something like us. :) )

      If someone would like to know what issue of Nat. Geo. was, I'm sure I could dig it out and let you know.

      There's no set rule stating that life has to evolve in Earth-like conditions. However, the rate of chemical reactions is directly dependant on temperature. The actual formula for figuring out the rates is a bit complicated (unless you memorized the powers of "e"), but the simple rule of thumb is that the rate doubles for each increase of 10 degress Celcius.

      This means that in a cold environment (for example, Titan), chemical reactions would take place extremely slowly. On the other hand, in a hot environment (Mercury, Venus, a campfire), reactions take place quickly. See also: combustion.

      Also, in order to be able to move about and interact with it's environment, you need some combination of phases (solid, liquid, and gas). Too cold, and you end up with a living ice cube that can't do anything besides sit there. Too hot, and your life form evaporates and diffuses through the air.

      Now, with that said, there isn't any good reason to presume that life has to be exactly like us. They could use ammonia instead of water, silicon instead of carbon, etc. (Actually, the results aren't exactly the same, but it's still possible)

    Okay. Get past the title "Oily ocean found on distant moon", and that not-very-compelling image of a probe landing on titan (seen much better on Digital Blashphemy, thanks), and what does the article _really_ say?

    Basically, we found that kidney has a dark kidney-shaped feature, and a giant duck that might be rock and ice. The dark kidney-shaped feature might be some kind of liquid hydrocarbon, or maybe some kind of organic solid, or maybe just black rocks. The scientists quoted didn't draw any definate conclusions, and the real breakthrough was just getting a "quantitative map" of the surface.

    I find this to be interesting on its own, without the premature declaration that there's a huge sea of oil on Titan.

    What I also find interesting is that the pictures from the ground-based telescopes were clearer than those of the Hubble.

    SAUDI ARABIA ANNEXES TITAN
    "Mine, Mine, All Mine," Vows Gleeful King


    DHARAN, SAUDI ARABIA (AP) - In a bold and unprecedented move, an Earth-based nation has laid claim to an entire celestial body. When the BBC reported that astronomers had located a potential "ocean of oil" on Titan, Saturn's largest moon, the government of Saudi Arabia quickly mobilized and annexed the satellite using a highly questionable procedure. Saudi Arabia is an extremely oil-rich country, and most analysts believe that the move by the Saudis serves only to increase their oil reserves.

    The United States' reaction to the annexation was swift and negative. "We would advise Saudi Arabia to carefully reconsider their decision," said State Department spokeman James Rubin. "The Chinese attempted to annex the Jovian satellite Europa in 2010: Odyssey Two, and you saw what happened to them. This move is reckless, and may have far-reaching unintended consequences." Similar statements were released by Russia, France, Tahiti, and Swaziland. As of yet, no country has indicated that they will officially recognize Titan as Saudi soil.

    The reaction from Titan was equally fervent. "Under no circumstances," stated official satellite spokesbeing Gkklotrff Bdssuirghed, "will the citizens of Titan accept any intrusion by the government of the Kingdom of Saudi Arabia. We have never done anything to you silly Earth-bound two-legged bastards; all we ask is that you pay us the reciprocal courtesy in return." The official Titan News Agency reported that the Titan military was in a state of "high alert."

    The Saudi government, however, is downplaying the interplanetary outrage. "What we have done, we have done under the auspices of international law. If the United States, or Swaziland, or whatever, wished to annex Titan, it could have done so long ago," said a government spokeperson. "Waahh, waahh, waahh. You're just jealous because we did it first."

    In the meantime, however, Saudi Arabia is preparing its massive space program for an expedition to the distant moon. While the government is closely protecting the identity of the five astronauts that will make the trip in the top-of-the-line Saudi Shazam al-Rocket spacecraft, the Associated Press was able to speak by telephone to one of them. "I'm very pleased to be going," said the astronaut, who spoke on the condition of anonymity. "I am confident that Allah will protect us and keep us safe on our way to Titan. Hopefully, when we get there, we'll find 'Allaht' of oil," the astronaut joked.
