SETI Finds Interesting Signal
Several readers sent in notes about an interesting signal discovered by SETI. No real evidence of Someone Out There, but not fully explainable either. Another reader submits a blurb suggesting that aliens should send spacemail, not signals: "Rutgers electrical engineering professor, Christopher Rose, has an article on Nature magazine's cover today describing the most efficient way for our civilization to be discovered by aliens. On this question of better to 'write or radiate', his conclusions: better not to send radio transmission, when physical media like DNA on an asteroid can declare a terrestrial presence. Similar to what motivated Voyager scientists to attach a plaque for the outbound trip. Rose has some great information payload sizes as examples (like the entire information equivalent for our global genome fitting on a 100 pound laptop!)."
No one's gunna pay attention to us until we have warp drive anyway.
The space unintentionally left unblank.
When dealing with the vastness of space, how can you advocate physical over transmission. The article does nothing to describe why sending an object with mass 1/1000000 the size of a planet that we would notice is somehow preferable to trying to boost a signal.
Often wrong but never in doubt.

Voyager scientists attach a plaque on the outbound trip - aliens attach a plague on the return trip.
...I hear about something like this, I just have to wonder how we know what we're looking for. I mean, seriously... life outside of our solar system is probably not at all like the life we find here on Earth. At least, I sure hope it's not. In any case, how do we even know what to start looking for?
If this turns out to be an MP3, it looks like someone is gonna get sued (it would be filed as RIAA v. Zorack Doe)
Physical objects are a tad harder to find. We would be happy to find a civilization like our own... however, we didn't notice a rather large until three days after it had almost hit our planet. The other real snag happens to be major as well - it doesn't travel at the speed of light. Puts things on a slightly larger timescale, doesn't it?

But it could also be WAY too fricken big for us to be detectable...
(try crunching some numbers WRT the invention of radio transmitters, the speed of light, and the distance to nearby stars)

Oh what are you thinking?!
Everybody knows that if you send some genetically engineered organism into the vastness of space, it will only return far more advanced - and destroy us for sending it's ancestors to a dark and empty prison.
Duh.
Like Teddy with an elephant gun.
Slashdotted my ass. We were never supposed to know about this. The government cover-up is underway.
I think I might rather hang onto this information until we're sure our new-found neighbors are friendly.
SETI isn't looking for messages people are sending us, it's looking for evidence that somebody out there is communicating by radio. As an example, other civilizations within about fifty light-years or so would be able to pick up TV signals from us, and radio could be detected for almost twice the distance. None of these are intended as extra-terrestrial communications, but they'd be evidence that we're here.

I mean, it would be cool to discover intelligent aliens and all, but why have them discover us?
I like to surf the internet, but for crying out loud, I have a firewall. I see the Internet, the Internet doesn't see me.
I'd say just be cosmic lurkers until we are damn sure it is safe to be sticking our nose into things.
Of course the odds of anything on this topic happening (good or bad) are so poor that I don't think anyone has to worry.
This issue is a bit more complicated than you think.
How true. Consider that the male image on Voyager had a teeny tiny penis, and it all starts to make sense.
The other option is a return message on a plaque, depicting a male alien with really large reproductive organs. That'll tell us, more than almost anything else, what sort of mentality we're dealing with.
...it read "PH1RST P0ST!!!"
Don't worry, NASA scientists have already modded them down.

I sent in this article - very cool read and makes me wish for FTL travel!
...There are other oddities. For instance, the signal's frequency is drifting by between eight to 37 hertz per second. "The signal is moving rapidly in frequency and you would expect that to happen if you are looking at a transmitter on a planet that's rotating very rapidly and where the civilisation is not correcting the transmission for the motion of the planet," Korpela says.
New Scientist is reporting that the signal "also happens to be the best candidate yet for a contact by intelligent aliens in the nearly six-year history of the SETI@home project, which uses programs running as screensavers on millions of personal computers worldwide to sift through signals picked up by the Arecibo telescope...*snip*
What if we deliver this encoded DNA to a species that uses, say, a silicon matrix encoding their genetics?
Why would they even look at DNA, if they didn't realize it was a way to encode info as well as the foundation of life for us?

Ok, now if they can't decipher or get anything out of that signal I think they should made available a file with the data to anyone who want to try to poke and study the thing. They found it with the help of the collectivity so they should give to the collectivity the option of working on it. They should also give the exact coordinates of the signal.
Yahh, hiii haaaaa! -Major Kong, from Dr. Strangelove
Actually, the other problem (probably bigger, even) is that more and more of our communication has gone wireline or low-power line of sight. We're no longer radiating quite as much easily detectable RF, and the SETI guys assume that there's only a finite amount of time where a civilization would unintentionally radiate.
Basically, I've heard it called the window and door problem - we have a window of 50-100 years (I forget whose estimate) when a civilization is accidentally radiating to find them, and then we have to wait for them to open the door by transmitting intentional beacons.

Here is an article that is un-slashdotted as of 0057 Universal Time.

You do realize that in the SETI context "advanced civilization" means "technologically advanced civilization"? If they are an advanced civilization they will have a basic understanding of science, of how the universe works. Electromagnetism is an elementary part of that understanding. Our methods for establishing communication do not have a western or human bias. Counting off prime numbers is pretty neutral, an advanced civilization should recognize that this would be a quite improbable natural phenomena. Similarly the frequencies we would use for such signals would be pretty neutral, a multiple of a universal constant, another improbable natural phenomena. Some things are universal, not products of human or western culture.
Dear Sir/Madam,
Let me start by introducing myself. I am Sub-Commander Qulon Zarg, credit officer of the Trans Galactic Bank Ltd. I have a concealed business suggestion for you. Before the Pulson/Darius war our client Overlord Argus Vader who was with the Gandor Star Force and also business man made a numbered fixed deposit for 18 calendar months, with a value of Twenty millions Five Hundred Thousand Zerglian Dollars only in my branch. Upon maturity several notice was sent to him, even during the war early this year. Again after the war another notification was sent and still no response came from him. We later find out that the General and his family had been killed during the war in bomb blast that destroyed their entire planet. After further investigation it was also discovered that Overlord Argus Vader did not declare any next of kin in his official papers including the paper work of his bank deposit. And he also confided in me the last time he was at my office that no one except me knew of his deposit in my bank.
So, Twenty millions Five Hundred Thousand Zerglian Dollars is still lying in my bank and no one will ever come forward to claim it. What bothers me most is that according to the to the laws of my country at the expiration 3 years the funds will revert to the ownership of the Episilon Prime Government if nobody applies to claim the funds. Against this backdrop, my suggestion to you is that I will like you as a foreigner to stand as the next of kin to Overlord Argus Vader so that you will be able to receive his funds.
WHAT IS TO BE DONE:
I want you to know that I have had everything planned out so that we shall come out successful. I have contacted an attorney that will prepare the necessary document that will back you up as the next of kin to Overlord Argus Vader, all that is required from you att his stage is for you to provide me with your Full Names and Address so that the attorney can commence his job. After you have been made the next of kin, the attorney will also fill in for claims on your behalf and secure the necessary approval and letter of probate in your favor for the move of the funds to an account that will be provided by you.There is no risk involved at all in the matter as weare going adopt a legalized method and the attorney will prepare all the necessary documents. Please endeavor to observe utmost discretion in all matters concerning this issue. Once the funds
have been transferred to your nominated bank account we shall share in the ratio of 70% for me, 25% for you and 5% for any expenses incurred during the course of this operation. Should you be interested please send me your private phone and fax numbers for easy communication and I will provide you with more details of this operation. Your earliest response to this letter will be appreciated.
Kind Regards,
Sub-Commander Qulon Zarg

So here I am sitting around wondering when this will hit Slashdot, so I send the link to my buddies and stuff and go "damn, site's offline" and curse the script kiddies and go on with my day.
:)
But it was you guys all along! [StrongBad tear]
Seriously. To your credit, I first found out about SETI@Home on Slashdot and ran it for years on spare computers.
Now I have made SHGb02+14a my beeyotch.
Then you guys Slashdotted the article before my mom could see it.
As Carl Sagan's pointed out in is book, Contact, no matter how complex or compelling the message from beyond, there will be people who will think it's a hoax.
Or to put it another way, even if God himself this very day with his own hand placed a crucifix in orbit around the earth replacing the moon, science would explain it.

Nobody seems to have noticed this paragraph of the Article: So, everytime they detected it it started at 1420 MHz and then started shifting? How could asignal from 1000 Lightyears away react in such a way? Do you think the aliens restart the signal every time we are looking?
No, sorry, everyone. This looks pretty much. like a malfunction of the telescope in Arecibo.
Did I miss something or is it the first time the overlords are supposed to be intelligent?
That might be something to welcome indeed.
You there, you must be almost thirty. Have you ever kissed a girl?
