Europe's New ET Life Search Programme 221

Posted by Hemos from the testing-the-galaxy dept.
hotsauce writes "The Guardian has a report on Europe's ambitious new programme to search for extra terrestial life. ESA has started a program called Cosmic Visions which will launch a series of satelites, starting with Gaia in 2011, and possibly culminating with the Exo-Earth Imager, a mission consisting of 10.000 3-metre mirror telescopes. The French are leading the charge with Corot in 2008."

        Yeah, from a CS view I see that. I was thinking of precision from chem... they know they have approximately 10 telescopes, to within .001 of a telescope; in reality there are 10.000394654(...) telescopes in use. :)

    • Yes, and for those who don't know, it is an error to write ten thousand as 10.000 when you are writing in English, regardless of your nationality. Using English as your language but a period/full stop as your thousands separator means you have an inconsistent localization, requiring the need for a "translation" such as the parent post to finish the job. Likewise, it is an error for an English speaker to use commas as thousands separators when writing in a language such as German.

    NPR [npr.org] did a story on the most efficient way to search for extra-terrestrial life, where it would be more efficient (energy/economic) to send craft out to distant solar systems rather than beam signals there. Apparantly the loss in signal strength is so severe (inverse square law) that signals get lost in the cosmic background.

        At point of sending, yes, lasers are very focused. However they spread very widely over interstellar distances. Still, from a conservation of energy point of view a laser is much more efficient than blasting radio in all direction.

        But I think it depends on the nature of the communiction. If alien civilization #1 at star A already knows #2 is located at star B then laser is absolutely the way to go. Radio is more of a shout in the dark method. Whether you believe there are wolves or other travellers in the dark depends on whether you shout.
    • did a story on the most efficient way to search for extra-terrestrial life

      Sending probes is beyond our technology as a way to search for life - you have to either expect a return contact from the more advanced civilization or radio back the findings yourself. We can barely pickup the Voyager signals and they're still in our own solar system.

      This is about looking for planets, then analysing them to see if they have the conditions to support life (oxygen, co2, methane). SETI is about trying to recieve radio signals created by intelligent beings out there.

      In short, this is looking for any sort of possible life, SETI is looking for "ET phone home".

      SETI is fundamentally flawed, since even now we on Earth are broadcasting less and less out into space. We're using microwave and lasers to talk to our satellites, and everything on the ground is getting wired, or fed from satellites.

      The days of gigawatt broadcasting over radio bands is winding to an end, so we only will have made "noise" for a century or so.

      One could assume an intelligent race would outgrow the technology just as we have, or never use it in the first place.

        SETI is not flawed, it's designed primarily to intercept signals sent on purpose towards us. Even if ET has long ago stopped leaking radio signals to space, they could easily beam us some messages.

        For the past few hundred million years, advanced ET could see that life is present on our planet. This is because of the amount of oxygen and water vapor in the atmosphere. With a large enough telescope ET could even observe continents on Earth.

        So it's not far-fetched to think that ET would call us.

        While I don't necessarily disagree, I don't think that we're necessarily looking in the wrong place. Imagine a civilization far in advance of our own using some sort of communications technology we can't even imagine as yet. Surely it wouldn't be too difficult for them to make a massively powerful radio transmitter to call out? In fact, I can see one very good reason to think there might be such a beacon made by an advanced civilization. Think about all the trials and tribulations we're going through right now, all this uncertainty about whether or not humanity will survive - about whether it is even possible *for* us to survive our technology. Then imagine we get a signal from space, from another civilization, one that went through what we did. "We're here, we survived, and you can too. Good luck, and welcome to the universe." Call me sappy, but I can think of no better message we could receive.

        It all comes back to Fermi's paradox. If there are intelligent (I prefer the term 'sophont') alien life forms out there, why haven't they contacted us?

        One solution says 'because they don't want to'. I find that solution very plausible at the current juncture. Odds are that if there is, in fact, a conglomerate of alien nations out there, they've set down a network of powerful signal-dampening sattelites around our solar system (the Oort cloud would be a good hiding place), controlled by a very strong AI which filters the transmissions reaching us, so that only natural phenomena and signals of our own making ever reach us. This could even be standard procedure for worlds below a certain level of technology. This is called the 'Prime Directive' solution, after Gene Roddenberry's Prime Directive from Star Trek.

        Of course, another (more Occam-friendly) solution to the paradox is "Because there aren't any"...

      This shows a deep lack of understanding about what is being searched for.

      The pattern being looked for is a pattern that cannot arise via natural processes.

      DNA can be explained as a result of natural processes. Note that I said CAN. It is only those processes for which a natural process can not be provided for which intelligence can be inferred.

      Consider the discovery of pulsars. They caused quite a stir at the time. But since a natural process was discovered that could explain then, the original thoughts that they might be evidence of intelligent life was quickly discarded.

      It is the same with life. At first it was believed to be miraculous, the result of a special creation. But as we learned more about how life actually works, we come to see that it can be explained as the result of natural processes. And thus not evidence of intelligent design.
