Isn't the Arecibo radio telescope able to send a radio message that a similar telescope could detect at a distance of tens of thousands of light years?

https://www.seti.org/seti-inst...

"The emission was equivalent to a 20 trillion watt omnidirectional broadcast, and would be detectable by a SETI experiment just about anywhere in the galaxy, assuming a receiving antenna similar in size to Arecibo's."

As I understand it, earthquakes are kind of like that. At millions of points along a fault, various rock structures prevent the plates from slipping past one another. Periodically, those break or shift, allowing the plates to continue sliding. An earthquake occurs when the stress becomes sufficient to cause one of those rock structures to break or shift so that the plates can move again. The size of the earthquake is proportional to the amount of pressure that was on that structure prior to when it broke or shifted. So to predict an earthquake accurately, you would need to know the stress on not the fault as a whole, but at least ostensibly on every single rock structure of a given size or larger within the fault system.

And of course some rocks are stronger than others depending on composition, pre-existing cracks, rock orientation (because of the grain).

Having said this someone else did reply linking a couple of interesting articles suggesting more ways of detecting stresses.

Yes you can measure it, indirectly, using ion analysis from p holes. http://www.seti.org/seti-insti...

Or you may watch the ionosphere.

I have a high altitude system and a low altitude system (10 ground stations) and both give me the Total Electron Content of the ionosphere to support a patent in the tomography of the ionosphere.

Friedemann Freund is a man with a lot of ideas.. At Yuri's night at the NASA Ames campus, he demonstrated this magnetic pulse-from-rock by using a dense column of rock and a hydrolic press. He had a saucer sized capactive sensor that was tied to a small microcontroller for remote-sensing/field usage that could detect the change in the electric feild near the rock column as it was compressed. He mentioned that he'd instrumented a fault line. He mentioned that the current released was strong enough to ionize the air around the faultline if a lot of rock was compressed at once. Compression can happen before an earthquarke, which is why it may serve as an early warning detector. He also thinks that some animals go nuts before an earthquake because they can smell traces of the the ionized air.

Here is his profile: http://www.seti.org/users/frie...

He also has some interesting ideas about the origins of life on earth, specifically the chemistry of mud on the ocean floor, about how long polymer chains can form; the working material for the first cells, and alternative theories of oxygen formation in our atmosphere..

If there aren't clouds you probably won't see much anyway. According to SETI the estimated peak rate in London is 0.2 meteors per hour.

In his recent book "The Social Conquest of Earth", E.O. Wilson argues against manned missions. His claim is that "nobody is going to emigrate from this planet, not ever.". He calls sending people to the planets instead of robots "a circus stunt".

The book goes on to claim that the dream of colonizing the stars is a "cosmic myopia" and a "dangerous delusion", particularly if we see it as a "solution to be taken when we have used up this planet". He then presents the Fermi Paradox about why we don't see other space critters. In addition, he points out that if a single species had in fact started colonizing the stars only a billion years ago, that by moving from star system to star system only every million years, they long ago would have occupied every habitable star system in the galaxy.

It is a very interesting and thought provoking book, but I was not as convinced by his arguments here as by other arguments. This may be due to bias on my part, caused by my early exposure to Star Trek.

Stop trying to create and then defend one thing.

Fat intake has gone through the roof, as has sugar and salt. So we are eaitng more food, and that food has more sugar/fat/salt then before.

"Up-scale restaurants generally have a tendency to cook the old school way,"
name THAT logical fallacy, sheesh.

"People have been consuming excessive portions of fat for 100s of years without an obesity epidemic"
That's not true at all. for 100's of years most people dind't get enough to eat.You would have to be rich to eat excess fat 100 years ago. Hell, it would have been hard to do 50 years ago.

" than age old delicious recipes consumed by our far thinner ancestry."
Idiocy. Imagine eating that meal 6 times a day. That is the problem.

And it's sugar. Bleached, unbleachs cane, beat, corn that's an issues. Their is no logical reason to bring up one type of sugar.
In fac,t it derails the discussion. All sugars that aren't backs with the correct level of fiber are bad for you.

I good podcast that I listen to discussed this recently.
"Big Picture Science: Skeptic check Sweet Truth."
http://radio.seti.org/

Does she have a role in this team? I didn't see her name except in references. Cynthia gave interesting presentations about Europa, "When looking for life, go where the water is." Her bio at http://www.seti.org/users/cphillips

On another thread... alright you guys, cue in the references from "2010"....

to do an interview on slashdot.

Also, get their podcast. It's lame puns and excellent science

http://radio.seti.org/

Seconding the interview request for Seth Shostak. He's an incredibly bright, level-headed skeptic who looks up at those same stars we all do and thinks big thoughts.

Also, I enjoy that podcast a great deal. Any podcast that gets Leonard Susskind as a guest (he's in the latest episode) is pretty cool in my opinion.

Sorry to disappoint, but TFS is way off. (So unusual for slashdot...) Actual information is here.

"Space situational awareness" is not Colonel O'Neil looking out for an invading alien fleet. It means tracking satellites and space debris to avoid collisions. The USAF is renting the SETI array to track GPS satellites.

Just to make clear: The Air Force does not want to check Kepler 22b. Here's what they want:

AFSPC, through the Space Innovation and Development Center (SIDC), is currently researching the possible use of the ATA to augment the already extensive sensors of the Space Surveillance Network, potentially leveraging the array to help increase space situational awareness. Initial demonstrations show promise for the ATA to track transmitting satellites in Low Earth Orbit, Medium Earth Orbit and, most promising, in Geosynchronous Orbit (GEO), which is home to the most costly, highly-utilized, and vital satellites that orbit the earth. A collision and subsequent debris field in GEO could permanently remove the GEO belt from worldwide use.

I was just listening to this week's episode of Big Picture Science http://radio.seti.org/ where they addressed this issue, and the scientist they interviewed claimed that the toads that started this whole thing naturally migrate every year. Not sure who's right, but I'm more likely to believe it was a fluke until they can actually prove the ability to predict an earthquake before it happens, and not after.

SKA - The SKA will give astronomers insight into the formation and evolution of the first stars and galaxies after the Big Bang, the role of cosmic magnetism, the nature of gravity, and possibly life beyond Earth.

SETI, the Search for Extraterrestrial Intelligence, is an exploratory science that seeks evidence of life in the universe by looking for some signature of its technology.

I use Google Reader to gather data from any rss feed of interest and also download weekly about 60 podcasts from various sources each week using the Feedreader aggregator. I have to plug, in particular, podcasts (or videocasts) from This Week in Virology, This Week in Parasitism, and This Week in Microbiology, all available via a starting point of www.twiv.tv . (If you think Parasitism is not interesting, listen to TWIP 22.) The Naked Scientist based in Britain offers a nice weekly collection of news gathered from that area. The Australian Broadcasting Network at www.abc.net.au/radio/ offers podcasts about technology oriented towards that part of the world. The Canadian Broadcasting Corp and the BBC also offer podcasts which include new developments in all areas, but don't allow you to specialize in one area, such as medicine or computers. Futures in Biotech ( http://twit.tv/FIB ) has produced some terrific interviews in that area and Leo Laporte and his This Week in Technology does a few podcasts that offer more than his usual troubleshooting genre. http://www.podnutz.com/ is strictly computers, but three podcasts in particular are of interest as trendsetting. They are 274, 302 and 316. They deal with the development and growth of Lisa Hendrickson's career. She's a female computer troubleshooter who is rapidly building a large business that repairs computers remotely and worth watching and learning from as an example of how to grow a new business in the US. The Howard Hughes Medical Institute produces podcasts and videocasts about advancing technology Do a search for NIH Videocasts for presentations by this organization. Econtalk may not be strictly technical, but has outstanding interviews about developments and history that disproves that idea that economics are dry and boring. I've been saving a list of Best Podcasts for over a year and they number now about 90, but amount to over 2GB, so are not readily posted. I also have the addresses of podcasts that are plugged into the Feedreader aggregator that I'll try to add here in case that's of interest if the moderator agrees to include them. Several of these were worth noting, too, like NY Times Tech Talk and RadioLab: http://rss.conversationsnetwork.org/ppq/56641.xml http://podcast.seti.org/index.xml http://www.rtve.es/podcast/radio-5/asunto-del-dia-en-r5/SASUNTO.xml http://feeds.feedburner.com/booksandideaspodcast http://downloads.bbc.co.uk/podcasts/radio4/clickon/rss.xml http://feeds.feedburner.com/Cyberspeak http://feeds.feedburner.com/diffusionradio http://www.econlib.org/library/EconTalk.xml http://www.npr.org/rss/podcast.php?id=510030 http://feeds.feedburner.com/GlobalChallenges http://downloads.bbc.co.uk/podcasts/worldservice/healthc/rss.xml http://www.hhmi.org/biointeractive/HHMI_Lectures.xml http://podcast.thelancet.com/laneur.xml http://www.materialstoday.com/rss/podcasts/ http://www.nytimes.com/services/xml/rss/nyt/podcasts/techtalk.xml http://dow

Two of the GSOC projects this year were for the SETI Institute. Apparently, the SETI Institute proposed 5 projects, but only 2 of them were funded.

I would guess that at least one off them was a project "to develop an algorithm capable of producing a fictitious but convincing pattern out of vast amounts of random data in order to justify further funding for the SETI project".

Two of the GSOC projects this year were for the SETI Institute. Apparently, the SETI Institute proposed 5 projects, but only 2 of them were funded.

Interesting that they are one of the sponsored organizations for the Google Summer of Code. I guess we only have to wait a few hours to find out if any talented students will get awarded the chance to work on this since Seti Institute was mentoring a couple of projects

>>>This planet has an expiration date.

Yeah 5 billion years into the future.

Actually it's going to be around 1 Million years. We're slowing moving out of the "Habitable Zone", which we're already on the inner edge of to begin with, and that will happen much sooner than when the Sun begins to expand during it's Red Dwarf stage. http://www.spacedaily.com/news/extrasolar-99m.html
Also the Moon is moving away from us and in about 1-2 Billion years our axis wont be stable which will cause profound weather changes. http://www.seti.org/Page.aspx?pid=769

Here's the link to the original paper.
While not a specialist, the paper looks to me FAR from suggesting anything close to what the headlines claim.
The "conclusions" of the paper state:

The presence of clay and carbonate in the Nili Fossae region suggests that biomarkers (if present) could have been preserved within these rocks, as they have been in the Pilbara region.

May be it's just the authors being understandably cautious on such a topic, on a peer-reviewed journal, with the language they are using.
(I reckon it's more likely, though, that it's the headlines erring on the excitement.)

This provides and entirely separate channel with its own bandwidth in addition to traditionally understood modulation. They're right to be excited about it; it has the potential of being just as big in scope as was the invention of radio.

Isn't one of the hugest factors in the Fermi Paradox the "Great Silence" aka that if life in the universe is so abundant why don't we hear their radio transmissions?

Now, how many other "channels" out there do you think exist that we simply have no grasp or knowledge of?

Does this open up a new potential medium for listening?

SETI researchers look for narrow-band signals, the type that are confined to a small (usually 1 Hz or less) spot on the dial. But if you have a cellular phone, you may be aware that a lot of communications on Earth are now done using a technique known as "spread spectrum." The broadcast signal is dispersed over a wide range of frequencies. What if ET is also engaged in spread spectrum broadcasting? Would our searches pick up his call? That depends. If the signal is strong enough, it might still be detected with current SETI equipment, although weak broadcasts will be missed. There's little doubt that in the future, with greatly increased computer capability, our search will encompass these other types of communications.

http://www.seti.org/Page.aspx?pid=558#WrongType

Who wants to bet that when ET phones home that they don't bother pointing a powerful constant carrier wave at Earth while they're doing it, but instead make it very much point-to-point directional and use signaling techniques that we haven't thought of...

I verified the EXIF data, but it is wrong. Likely because the 800mm lens was incorrectly reporting the focal length to the camera.

Going directly to the re-entry observation team information shows that it was, in fact, a 800mm lens.

The word "Kitting" in the filename matches with a researcher (Chris Kitting) who was scheduled to use a D700 with a 800mm lens to track the re-entry.

Sometimes I think people on SlashDot are not necessarily the smartest in the world.

There are plenty of people advocating for space exploration, both manned and otherwise (myself among them!): http://www.spacecoalition.com/ http://www.sciencedebate2008.com/www/index.php, http://marsproject.com/, http://www.seti.org/, http://www.committee4spaceadvocacy.org/, http://www.planetary.org/home/ People are advocating. The problem is that no one is listening. Our country has been deaf to the benefits of space research for 20 years now, and it's not going to change. It's only going to get worse as our kids get dumber and stop getting math, science, and engineering degrees. Is my generation going to be the last to take a shot at it? I sure hope not. But unless it gets some serious attention, and soon, the United States is finished as a space-faring nation.

SETI is important not just because it could find aliens. There is the distinct possibility that we are alone in the universe (not that likely in my opinion). A positive result would be more interesting than this constant negative we have been getting but it is important that we find out what is going on. Just because we may never see a positive doesn't mean we should stop. Having the evidence that we are indeed alone is just important as having evidence that life exists out there.

IANA Scientist, but the search we have performed so far is by-no-means exhaustive. From the SETI Faq:

while there are hundreds of billions of stars in our galaxy, less than a thousand have been scrutinized with high sensitivity.

Although SETI has been searching for nearly fifty years, with no solid evidence, we have currently studied less than 1/10,000th of a percent of the galaxy with "high sensitivity". It is still too early to make any conclusions.

Can someone help me with these two applets? They make no sense to me.

There's two little Java web applets called FLUXTIMATOR that allow you to put in your location and it will show you the expected number of shooting stars per hour for a ten hour time frame. However, because the experts can't agree on exactly when the peak will occur, there are two different little FLUXTIMATOR applets. The first one is based on the assumption that the peak occurs at 2h00m UT. The second one is based on the assumption that the peak occurs at 6h40m UT .

I live in the mountains outside of Denver Colorado. Our time zone here is Mountain Standard Time(MST). MST is seven hours behind Coordinated Universal Time(UTC). So, MST = UTC - 7.

First, I put in "10 Quadrantis 02:00" - "Denver, US" - "Mountaintop" - "Jan 3-4, 2008" - "DST=No". In this case, the graph indicates that the "Peak Time: 04:16" and the peak rate is about 28.8 meteorites per hour. This is a little confusing to me, however, as I would expect that if the we are "Assuming the peak is at 2h00m UT", then I would back 7 hours out of that and I would assume that the peak time in Denver would be 7:00 p.m. MST on Jan 3rd.

Secondly, I put in "10 Quadrantis 06:40" - "Denver, US" - "Mountaintop" - "Jan 3-4, 2008" - "DST=No". In this case, the graph indicates that the "Peak Time:03:52" and the peak rate is about 52.7 meteorites per hour. In this second case, where we are "Assuming the peak is at 6h40m UT", I would assume that the peak would occur at 11:40 MST.

Can somebody tell me what I'm missing here?

At least in some places, the ring particles are quite close together. Check out this illustration. The particles vary in size from dust grains to boulders as big as buildings. The wildest thing is that the rings are about 280,000 km wide, but less than one thick.

Two privately owned Gulfstream GV aircraft are made available for this mission, providing a total of 21 windows to the shower for 24 participating researchers and volunteers.

I was paraphrasing what Jill Tarter said at an ASP conference that I was at a few years back. Obviously there is going to a variety of expectations and how they state those expectations will be different depending of the audience.

SETI is no longer funded by NASA due to a congressional ruling, and hasn't been for some time.

At its current state, the institute is funded entirely from private donations by those who have hope that the discovery of ETI would bring wonderous advances to our society.

If you think its a worthwhile persuit, which I think it is, donate. http://www.seti.org/

If not, then don't donate. Unlike NASA programs, this one carries your democratic approval of support.

In practice, the Square Kilometer Array is intended to have a collecting area close to the physical area of one million square meters - requiring almost no gaps to exist between dishes.

My first calculation would be for dishes with a wider gap, which would give you much greater flexibility on pointing the damn thing, as you can't see through the other dishes. Personally, I consider this to be a much superior design, even though it would cost on the collecting area. Unfortunately, they are the ones being paid, even if I am the one who is right...

By way of comparison, Jodrell Bank Radio Telescope is a paltry 76 meters across, for a total collecting area of 4560 square meters, and that's one of the largest single steerable telescopes out there.

I'm going to guess that a collecting area about nine times that of Jodrell Bank, combined with a resolving ability that is, well, astronomical, you would get a very respectable image of Earth-like planets around other stars. If we accept the SKA group's claims, then you've a collecting area 250 times that of Jodrell Bank.

I first heard the 100LY=1 pixel resolution with SKA from Jill Tarter, head of the SETI Institute at a talk she gave at NASA Langley. From crunching the numbers, I can see nothing that could seriously contradict the claim. Even if you assume my model is the more reasonable implementation, the complete MERLIN network that has been detecting jovian planets for some time has only a fraction of that collecting area - probably something like a quarter or a fifth. (Aside from Jodrell Bank, the next-largest radio telescope in the UK is a paltry 32 meters across.)

If we go with SKA's claims, then we're talking about collecting possibly hundreds of times the total radiation, which would definitely be enough to spot even the tiniest of worlds - provided it had some characteristic reflected in the radio spectrum.

(It's also worth bearing in mind that networks such as MERLIN, which are hundreds of kilometers across, are set up for VLBI - very long baseline interferometry. That's fine, when you're talking about gas clouds or stars, but is probably none-too-hot for spotting very fast pulsars or rocky inner planets. On the other hand, a kilometer would let you use regular interferometry, which means these things would show up quite nicely.)

There are three drawbacks to all of this, and I'm surprised none of the posters has commented on them (so far). First, interferometry requires very exact timing of all the delays in the system, or it won't work. Let's go with the SKA estimate and say the dishes are 1 meter apart. Your clock must count an integral number of ticks for every meter the signal travels from the dishes, even after allowing for the natural variation in the data lines varying the speed of the signal. This is some astonishingly serious timekeeping.

The second problem is to keep the signal noise-free. Easy, for a giant single steerable dish - you plunk it in the middle of nowhere and surround it with a huge Faraday cage that only obscures the horizon. When you've a few tens of thousands - or millions - of very small dishes, the problem isn't so easy. The terrestrial radio sources will be far harder to screen out - not just

Please see "Declaration of Principles Concerning Activities Following the Detection of Extraterrestrial Intelligence" on SETI website. http://www.seti.org/site/pp.asp?c=ktJ2J9MMIsE&b=17 9287

They have outlined a nine step program/protocol. Step 2 says "The discoverer should inform his/her or its relevant national authorities." Interestingly in Step 9 it says "Should credible evidence of extraterrestrial intelligence be discovered, an international committee of scientists and other experts should be established to serve as a focal point for continuing analysis of all observational evidence collected in the aftermath of the discovery, and also to provide advice on the release of information to the public."

In essence, whole list of people have to approve before any information can be made public.

So nobody can keep a secret?

Recall the Mars meteor ALH84001? Stanford University folks played a big part in researching it. After research of about two years, they claimed that micro-fossils were apparently discovered in that meteor. Interesting thing is that the Stanford lead scientist did not even tell his family that he was doing this research! After research was finished, White House apprently reviewed this result for two or three weeks before agreeing that it could be released to public. Mind you, this was for an apparent microfossil that may have existed about 4 billion years ago.

If there is so much secrecy for apparent micro-fossil, what do think may happen if "they" detected "green men" zipping around in UFOs? Even openly published protocols like SETI's say that detection needs to be kept secret, till proper clearance is obtained. Yet many people blissfully seem to assume that any detection will be on evening TV news.

Here or here, a very nice article on the project, "Margaret Turnbull and Jill Tarter have a new list, called HabCat: A Catalog of Nearby Habitable Stellar Systems." (2003) Interview included.

Interesting that starting with the Hipparcos catalog of 120,000 stars and skipping all with major problems for life ("cataclysmic, eruptive, pulsating, rotating, or X-ray stars", low metal content systems, rotating too fast or too much UV or bad size or composition), left 1 star in 6 still potential life bearers.

Wiki on HabCat and Turnbull. The Turnbull page has a link to a PDF, which is a very interesting scientific paper about how the list of habitable stars was made.

Wiki article on the Terrestrial Planet Finder, which uses Turnbull's list of 5000 candidates within a 100 light year radius. List of Top 100 candidates. Note 18 Scorpii at 46 light years is number 62 in the list, and 37 Geminorum is not listed.

The highest ranked 2 candidates in that list are just 4 ly away from Earth, at Rigil Kentaurus, and then Tau Ceti at 12 ly. There is one at 3 ly and some others at 19, 20, 24 ly too.

Allen Telescope Array

Turnbull's top 10 list includes 51 Pegasus, where in 1995 Swiss astronomers spotted the first planet outside our solar system, a Jupiter-like giant.

Others include 18 Sco in the Scorpio constellation, which is very similar to our own sun; epsilon Indi A, a star one-tenth as bright as the sun; and alpha Centauri B, part of the closest solar system to our own.

Known by all /.ers for seti@home, it was the SETI Institute that made the discovery in cooperation with NASA.

In case you don't know SETI stands for The Search for Extra-Terrestrial Intelligence.

From http://www.seti.org/site/lookup.asp?c=ktJ2J9MMIsE& b=179295 It is a passive experiment, designed only to look for signals, not to send them. However, humankind has been unintentionally transmitting signals into space - primarily high-frequency radio, television, and radar - for more than fifty years. Our earliest TV broadcasts have reached several thousand nearby stars, although any alien viewers would have to build a very large antenna (thousands of acres in size) to detect them.

The project that could be risky is CETI - Communication with ExtraTerrestrial Intelligence. Unlike SETI, which is a passive, listening pursuit, CETI attempts to initiate a dialogue with intelligent extraterrestrials. It does this by actively sending out coded signals at specific target stars, star clusters, or galaxies.

I like SETI institute's "Are We Alone" podcast very much. I think it's their radio show and still retains the advertisings, but the debates are usually pretty interesting. RSS is at http://podcast.seti.org/index.xml

I think this is why Paul Allen invested so much money in SETI. Sounds like Steve was really pumped before coming out onto stage.

At least the ground stations. Of all the spectrum out there the space communications bands are heavily gaurded - you don't want your new billion-dollar sat sent crashing to earth because of some yahoo's CB.

From: http://pds-rings.seti.org/voyager/datasets/rss/vg1 sinst.html

            The spacecraft radio system was constructed around a redundant
            pair of transponders. Each transponder was equipped with an
            S-band receiver (2115 MHz nominal frequency) and transmitters
            at both S-band (2295 MHz nominal) and X-band (8415 MHz nominal).
            Compared with S-band, X-band is less sensitive to plasma effects
            by a factor of about 10; use of both frequencies coherently on
            the 'downlink' allowed estimation of plasma content along the
            radio path. Use of X-band also significantly improved the
            quality of radio tracking data for gravity investigations.

Nothing against ignorant slashdotters, but you really don't think SETI is just some software, do you?

SETI@HOME != SETI

Not mutually exclusivly anyways.

In other news Cassini has spotted more previously unseen dark redish brown rings around uranus!

And in further news Michael Jackson denies reports that he misunderstood the term "star gazing at minor moons" in relation to McCauley Culkin.

We erected a tribute page on our website in his honor:

http://www.studentgroups.ucla.edu/abs/douglasadams /

Two years later, we finally ran our Big Event, with Bill Nye the Science Guy and Dr. Jill Tarter of SETI fame. We opened with a dedication to Adams. Here are pictures from the event:

http://homepage.mac.com/uniace/PhotoAlbum21.html

I've still got his voice on my answering machine! It'll be great to see him back on TV.

The other speaker at the event was Dr. Jill Tarter, Director of Research at SETI. Jodie Foster's Character in the movie, Contact, was based on Dr. Tarter. She was also a great speaker and cool to work with.

A fantastic suggestion! Here is the MP3 archive of previous shows for other interested new listeners out there like me.

If you are into space related science you may wish to listen to MP3s of the SETI Radio Network broadcasts. The topics are generally much broader than just SETI and the interviews with scientists and researchers are actually pretty good. They only produce an hour a week, but it will at least cover one of your commutes to work.

But I think that an attempt to find out at which of the two maxima are ionizing an argon atom should make the interference pattern go away.
that's what I thought. but how? can we attach a clock to the detectors? will shifting the detector screen at constant velocity serve as a clock? have a look at this: part4 you can refer to previous articles by links in the blurb.

Quantum Astronomy IV: Cosmic-Scale Double-Slit Experiment
by Laurance Doyle
Fascinating reading

This is slightly unrelated.

The article is about SETI, not SETI@home.

The latter is simply part of the larger SETI project that involves several telescopes, and independent computers looking for signals full time. SETI@home is used for processing lower priority areas of the SETI data.
