Seti Live Website To Crowdsource the Search For Alien Life

bs0d3 writes "Scientists need your help in the search for life beyond Earth. The SETI Institute is asking the public to join in its hunt for signals from intelligent civilizations out there in the universe. Anyone can register on the new website, SETI Live, to help analyze data from SETI's radio telescope devoted to scanning the heavens for signals from E.T.."

Brilliant idea

[Arancaytar]

It's not as if the humans most likely to spend time looking for ETI signals are also the most likely to be affected by optimism and confirmation bias. I'm sure we'll see many more signals than when boring computers did it.

Confirmation bias isn't an issue. Citizen Science works by people characterising various signals - such as categorising galaxies or pointing out transits in light curves. When someone flags up a potential find, the software then farms it out to multiple people. The current target for Galaxy Zoo is 30, which they deem enough for the moment. In addition the software does sneaky things like inverting images because apparently orientation is a big factor in whether you percieve a galaxy to be rotating clock or anti-clockwise.

Similar approaches apply to the Planet Hunters site:

We will always identify the simulated transit points in red after you’ve classified the star and list the radii and period of the simulated planet we injected into the light curve. The reason we don’t identify the simulated data first, is that if you knew the lightcurve had simulated events you might look at it differently. To be able to use the data from the simulated transits accurately, we need them to be examined in exactly the same conditions as the real lightcurves.

The people organising these sites know very well what humans are capable of misconstruing.

I thought the same thing. Although, from the site:

So it's an attempt to use the brain to manually pick out patterns? (I can't tell yet because the site may be overloaded - I get a "Loading..." screen but no updates.

I'm not sure that's a great idea, since the brain tends to make associations even if none truly exist.

Is SETI wasting its time?

[Froggels]

Is SETI wasting its time listening for radio signals? Just how powerful would a stable radio signal (such as a television type of transmitter)have to be at the source from a "nearby" star-system (say 20 light years) in order to be detected here on Earth, and as a corollary to that question, how powerful would an inadvertent stable signal on Earth have to be in order to be be detected at the same distance using similar equipment as that used by the SETI program? Do we even transmit anything strong and long enough that it could be detected at such a distance? I would imagine that the signal-strength would drop off too quickly to be detectable.

They are wasting their time if the (presumed) radio signals signals are like ours -- planet bound and not intended for other ears. If, however, someone is sending something this way intentionally, then it's well within the bounds of reason that we could hear it. With the relatively simple creation of an antenna and transmitter system in space, there's no reason a signal we could hear couldn't be produced. In fact, this is likely the only way, because the portion of the spectrum SETI is listening in isn't likely to be used for communications on a planetary surface, or if so, certainly not at the radiated power levels and steady aim required to light up any sort of detection at this end.

However, I would ask, why not light? You have a handy sun nearby, radiating all manner of otherwise unused visible energy... all you need to aim, focus and modulate that -- are mirrors. Seems like an altogether easier project, and certainly less expensive, plus less likely to have technical problems.

I knew a few people that worked at AOL in it's heyday. At one point AOL was one of the biggest contributors (cpu cycle wise) to SETI@home. I don't think it was a corporate idea. I believe that someone started installing it for their own personal reason and a sizable part of the company seemed to think it was a good idea.

But costed the company in terms of an increased power bill. You're lucky you weren't using modern GPU and CPU technology. Depending on how many powerful workstations you have in an office environment, you might pop the circuit breaker searching for ET.
