Planets abound in the galaxy. Over the past decade, scientists have discovered giant planets mostly by radial velocity techniques that detect the spectral shift in a star’s light caused by the to and fro tug of an unseen planetary companion.

This method has detected more than 200 planets, dominantly large close-in planets called “hot Jupiters” that are inhospitable to life as we know it.

In the near future, with the launch of NASA’s Kepler Mission in 2008, we’ll have the tools to seek evidence of Earth-size planets in the habitable zone of distant stars.

The search for life beyond Earth is the search for a good place to live, a habitable planet, in orbit about a long-lived star where life may arise and evolve. The first place we looked was at stars like our own Sun, a middle-sized, middle-aged star. G-Stars like the Sun are stable for about 10 billion years, which is a good long time for planets to form, and life to evolve. We also expected to find solar systems like our own with small terrestrial planets near the star, and larger gaseous planets farther out. This particular pre-conception was discarded with the discovery of hot Jupiters on 4-day orbits about their stars.

The idea that other, less-massive, dimmer stars than the Sun could also host habitable worlds has long been debated. A particular class, M-Stars, are of interest simply because there are so many of them—they are the most common star in the galaxy. They’re the cool stars that inhabit our neighborhood.

There’s considerable interest in the question of whether M-Stars could host habitable planets. Would the planets be tidally locked with one face always directed toward the M-Star? Would flares wipe out life on the local planet? If M-Stars could host habitable planets, life may be much more widespread that we’ve previously thought. Thus, M-Stars are of interest to astrobiologists including SETI scientists who are searching for life beyond Earth.

In July 2005, a team of SETI institute scientists, as part of our NASA Astrobiology Institute research program, brought together a diverse group of scientists to consider—frankly reconsider—the possibility of life on planets orbiting M-Stars. The results of this workshop are now published as the current issue of “Astrobiology”: Search for Habitable Planets Outside Earth’s Solar System. According to the publisher, “These reports present the preliminary results and conclusions from recent studies on the habitability of M Star Planets, which are planets about the size and mass of Earth that contain sufficient amounts of carbon dioxide (CO2) in their atmosphere to support a stable source of water on the planet’s surface. The habitability of terrestrial planets depends in large part on the distance of their orbit from the nearest star. Most of the stars closest to the Earth’s Sun are characterized as M Stars, and planets orbiting M Stars are of particular importance in the ongoing Darwin/Terrestrial Planet Finder missions being developed jointly by the U.S. National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA).”

The collected papers present the current understanding of M-stars, explore various aspects of M Stars (including dwarf M Stars and low mass M Stars), describe efforts to simulate Earth-like planets, consider the possible greenhouse effects in the atmosphere of Earth-like planets, and review the spectral signatures of photosynthesis.

“M stars are the most accessible, yet challenging, targets for habitable zone terrestrial planet searches,” says journal Editor-in-Chief, Sherry L. Cady, Ph.D., Associate Professor in the Department of Geology at Portland State University. “The potential for M Star habitable zone planets to evolve biospheres and retain them are but two of the many reasons to include M stars in the search for evidence of life beyond the confines of Earth.”

Why are SETI scientists interested in M-Stars? As Dr. Peter Backus, Observing Programs Manager for SETI, concluded in a preliminary report on the M-Stars workshop, “One…aspect of M dwarfs makes them intriguing for SETI: they may be ideal hosts for advanced technological civilizations because they live an extraordinarily long time. Stars like the Sun live (i.e., they fuse hydrogen into helium) for only about 10 billion years. No M dwarf that ever formed has yet to die; no M dwarf will die for more than another 100 billion years. With such long lifetimes, there are big possibilities for these small stars.”

Eavesdropping on ET Sooner Than We Think...

Eavesdropping on ET Sooner Than We Think

SEATTLE -- On Wednesday, January 10, here at the American Astronomical Society Meeting, theorist Dr. Avi Loeb from Harvard Smithsonian Center for Astrophysics led a press conference on the search for ET. “Soon, we may be eavesdropping on signals from Galactic civilizations,” said Loeb. “This is the first time in history that humans will be capable of finding a civilization like ours among the stars.” Loeb asserts that the proposed search will find “leakage” from transmissions equivalent to our broadcast television or military radars. SETI Institute’s Project Phoenix and UC Berkeley’s SERENDIP have both had the technical capability to detect intentional signals—beamed at Earth—with the equivalent power to military radars. Loeb’s search would expand the frequency range over which searches are conducted.

Loeb and his co-author Matias Zaldarriaga (CfA) suggest looking for accidental leakage from an alien civilization. They point out that the new Mileura Wide-Field Array’s Low Frequency Demonstrator (MWA-LFD), which is designed to study frequencies of 80-300 Megahertz, will pick up the same frequencies used by Earth technologies. On Earth, military radars are the most powerful broadcast sources, followed by television and FM radio. If similar broadcast sources exist on other planets, facilities like MWA-LFD might detect them. A SETI program at the MWA-LFD would complement other SETI projects. It will observe a larger area of the sky over a longer period of time and in a different frequency range.

“The MWA-LFD is a science instrument intended to study the distant, young universe,” explained Zaldarriaga. “But by piggybacking onto its normal observations, SETI researchers could use it to look for E.T. civilizations.” Loeb and Zaldarriaga calculate that by staring at the sky for a month, the MWA-LFD could detect Earth-like radio signals from a distance of up to 30 light-years, which would encompass approximately 1,000 stars. More powerful broadcasts could be detected to even greater distances. Future observatories like the Square Kilometer Array could detect Earth-like broadcasts from 10 times farther away, which would encompass 100 million stars.

Dr. Peter Backus, Research Scientist at SETI Institute also spoke at the press conference. He stated that the MDA-LFD represents a good example of the power of the new generation of radio telescopes. Taking advantage of advances in technology, these telescopes are more powerful and flexible than the traditional, large radio telescopes. Using this same design model, “large N, small D” (a large number of small diameter dishes) the Allen Telescope Array (ATA) will ultimately have 350 dishes, each only 6 meters across. The combination of these dishes will have the equivalent sensitivity of the Very Large Array in New Mexico and the Green Bank Telescope in West Virginia. Using programmable electronics, the signals from the 350 dishes can be combined to form up to 16 virtual antennas, each making independent observations. At the same time, other electronics can image an area of the sky at two different frequencies. The ATA will expand the search to higher frequencies that have far less interference and background noise than the lower frequencies that will be observed by the MWA-LFD.

Backus feels that this proposed low-frequency search is a good first step in exploring the lower frequencies for leakage or non-intentional signals. The unknown properties of such extraterrestrial transmissions will continue to provide challenges for low frequency searches. He looks forward to the outcome of this new observing project with the MWA-LFD.

News from Berkeley's Radio Astronomy Lab

2006-01-05T16:55:26Z

April 29, 2005
The DB reinit went fine. But then we had a problem with a recently installed software firewall. It was working when we left the lab yesterday but cut off the data service interface a short time later. We have switched off this firewall for now. Software firewalls are now required for all machines by campus policy but we will get an exception until ours is working. Note that we are, and always have been, behind a hardware firewall that works great. Given the length of this outage, service will be slow with lots of connection drops until the backlog is cleared.

April 27, 2005
We will be having a general outage tomorrow to do a database backup and to reinitialize our replica database server. The replica became corrupt last week due to a disk space issue. After this is done, we should not have to have outages for backups. We will start at 17:00 UTC. The outage will last several hours.

NOTE: They're saying the DB reinit went fine, but the system has been running slow over the weekend: uploads and downloads require multiple connection attempts, and work verification servers are either backlogged or not functioning properly. ...thom

Re: Reports of Extraterrestrial Intelligence near the Sun

2005-09-17T19:16:23Z

As you may know, the Sun has experienced some CMEs recently, and one of its sunspots is huge and has been highly active. But, did you know that there have been reports of flying saucers and possible ET sightings near these "spots"? Are they using our sun as an extradimensional doorway?!?!? For more info on the state of the sun, you can "tune" into:

As for the ETs, I think you are on your own...;-)

Best wishes and happy G star gazing,

Arecibo and UFOs

2005-06-25T01:17:28Z

----------------------------------------------
UFO Interest at Arecibo Radio Telescope
----------------------------------------------

According to information uncovered by Puerto Rican journalist Jorge Martin, the Aricibo Radio Telescope is not actually owned by Cornell University, but by the US Department of Defense. It has been used in atmospheric heating activities similar to those conducted at the HAARP facility in Alaska and has covertly participated in covert UFO investigations.

Martin offers as evidence an official internal memo from the Puerto Rico Emergency Management Agency, dated October, 1991, in which the director of the agency states that personnel from Arecibo are participating in a US study of heavy UFO and contact events that took place throughout Puerto Rico in 1991 and 1992.

Officially, Arecibo scientists maintain that UFOs are not real. Martin points out that there have been numerous documented and extensive UFO events near the radio telescope.

Two Arecibo employees have given Martin detailed descriptions of their own UFO sightings near the observatory. One of them, Security Officer Pedro Perez, stated that he had personally observed "a very rare flying device" while leaving the are of the telescope. He added, "the so-called UFOs are real, we have seen them here, so I do not have any doubts about that anymore."

None of the witnesses Mr. Martin interviewed had reported their sightings officially.

Residents near the telescope report seeing craft land and both human and humanoid beings in silver suits emerge from them. In addition, US military personnel in Hummers have been seen chasing brightly lit oval objects into the nearby Rio Abajo Forest.

The failure of SETI

2005-06-06T04:01:11Z

Never mind the fact that the seti data is gathered from a band of the EM spectra that we. ourselves do not use. Never mind that the intensity of the transmissions we currently release would not be picked up by similar equipmennt on our closest neighbor (if they were listening beyond the areas that we do).

What REALLY bothers me right now about SETI is the fact that we have at least 2 if not a dozen species on this planet of comperable intelligence that we can't talk to. These species (like dolphins, apes, whales, etc) have far more in commmon with use than a race under a diffferent sun, perhaps without DNA, certainly without our geographical features and other species to talk about.

I've spoken to people who train apes in sign language. They tell me that you can definitely tell that the apes are running on a lower octtane fuel than us, however, the intelligence we see isn't enough to descibe their social behaviours. In other words, the symbolic mind might be masking their true potential.

If this is the case, then our determination of their intelligence at "this" level versus their true, "that" level is determinate upon our inability to learn their forms of commmunication. We have always foisted a method of communication onto them, never have we learned to interpret and spek their language.

Okay, maybe apes aren't the best example. Our minds have shifted high into the symbolic areas and our language, though punctuated by physical expression, is not determined by it the way it is in apes, and lower land based mamilians. That leaves us with creatures that are dependant upon sound for their communication.

Dolphins and whales have shown to have incredibly complex aural communication. We understand exactly none of it. Once again, we can foist a new, simplified language upon them, but we have not yet interpreted theirs.

Which brings me to the point. We're very smug in our efforts to "listen" to the stars for another race that happens to be using the technology that we have proscribed for them (that we don't use ourselves). We imaginne that this other race will have enough in commmon with us to have a distinctive EM communication method. And I think most importantly, we imagine ourselves to be smart enough to interpret the signal.

Kids, there are HUMANs walking this planet that we cannot understand without an interpreter. In WWII, they were called Windtalkers, and were native Americans just chatting in their own language. How the hell are we supposed to establish communications with another race if we can't even cipher out the language of another set of humans on THIS planet?

This is what I see as the ultimate failure of the SETI project. It's entirely possible that you've already washed over screen after screen of alien language chattering away at you. But because we don't know what to look for, we have no idea it's there.

The Begginings of SETI

2005-05-07T16:50:54Z

SETI began in 1959 with the publication of an article in the journal Nature. Two Cornell physicists, Giuseppi Cocconi and Philip Morrison, suggested a project in which the presence of extraterrestrial life could be detected with radiotelescopes tuned into the microwave band (3 - 30 GHz). However, such an endeavour was already being planned by a young astronomer, the now famous Frank Drake, who in the spring of 1960 scanned sun-like stars for signs of ETI (extraterrestrial intelligence) with an 85-foot dish in West Virginia. Drake hypothesised that a more advanced ETI somewhere out there would be transmitting a signal to catch our (or anyone else's) attention. If so, then they would use one particular frequency of significance. Drake thought that 21 cm (1.4 MHz), the neutral band of hydrogen, would be it. After scanning for some time on this frequency, the young astronomer found nothing, and so ended what he called Project Ozma.

The first government-funded SETI-type project was not in America but in Soviet Russia. During the 1960s, the Russians set up omnidirectional antenna stations to listen in on the heavens in search of signals that might be of intelligent origin. While Drake used a highly directional antenna system, the Russian system would pick up radio emissions from all directions. This strategy meant that if a signal were found, it would be difficult to determine from which direction it originated. On the other hand, the Russian astronomers would never make the mistake of looking in the wrong direction!

It was not until the beginning of the 1970s that the United States government gave any serious thought to searching the Universe for radio signals of ETI origin. The first move was made at NASA's Ames Research Center, Mountain View, California, where several projects were set up to study the technical considerations involved. A team of outside experts was assembled -- including Bernard Oliver, who was on leave from the Hewlett Packard Corporation -- to produce a detailed report, known as Project Cyclops. By the late 1970s, NASA's Ames Research Center and the Jet Propulsion Laboratory (JPL) in Pasadena, California, were engaged in projects studying the technical aspects of any SETI-type endeavour. Ames concentrated on examining 1,000 sun-like stars for intelligent life, much like Drake's original Project Ozma, in what was known as "targeted search" using sensitive equipment to detect weak or sporadic signals. Meanwhile, JPL was concerned with systematic sweeps in all directions in a complete sky survey.

It was not until 1988, after a decade of study, that NASA HQ had the go-ahead and in 1991 started scanning the cosmos for intelligent life. A year later, Congress terminated funding! It seems very strange that after so many years of developing the technology, the US government should suddenly terminate funding when the actual search was only just beginning. But is there more to this than meets the eye?

Back in the early 1990s, the author had contact with an individual who claimed to be a former KGB officer involved in infiltrating the US National Security Agency (NSA). While serving his home country, a former Soviet state, he was involved in assessing the NSA's signals analysis techniques. Since the Soviet Union's collapse, he has had no authority to answer to and so speaks freely on such subjects. He says that SETI was no more than a cover for a more subversive program. Like the launching of Sputnik was no more than an exercise in deploying nuclear weapons, SETI was about eavesdropping on the enemy. This makes a lot of sense, as the technologies involved are very similar indeed.

For a practical SETI program, one requires a system that can scan at high resolution a huge bandwidth of frequencies. Not only this, but it must be able to detect the presence of intelligent transmissions. The latter requirement is achieved using powerful algorithms -- code-breakers -- which use probability mathematics to analyse the incoming data. Another requirement is that the system should be able to pick out weak signals buried deep within the background noise. Described here is no more than the perfect eavesdropping system -- a system that would give a government a great advantage over another.

SETI was the perfect cover and means of drawing in the country's brilliant minds: radio engineers, mathematicians and computer systems experts. SETI was a means of gaining the people's support, a project into which they could freely pump money. Meanwhile, the technology developed could be controlled and siphoned off for more subversive applications.

==========================================
All the governament wanted was the technology; the discovery of intelligence elsewhere in the Universe would at best be an inconvenience, so funding was terminated. But what of today? As there is no USSR, is there any use for such technology? The answer is yes, for now we are the enemy. It is our communications which are being tapped into, using the technology developed for SETI.
==========================================

Galaxy Quest

2005-04-07T18:08:41Z

Imagine, if you will, the leader of the fifth invader force speaking to the commander in chief...

"They're made out of meat."

"Meat?"

"Meat. They're made out of meat."

"Meat?!?"

"There's no doubt about it. We picked several from different parts of the planet, took them aboard our recon vessels, probed them all the way through. They're completely meat."

"That's impossible. What about the radio signals? The messages to the stars."

"They use the radio waves to talk, but the signals don't come from them. The signals come from machines."

"So who made the machines? That's who we want to contact!"

"They made the machines. That's what I'm trying to tell you. Meat made the machines!"

"That's ridiculous! How can meat make a machine? You're asking me to believe in sentient meat?"

"I'm not asking you, I'm telling you. These creatures are the only sentient race in the sector and they're made out of meat."

"Maybe they're like the Orfolei. You know, a carbon-based intelligence that goes through a meat stage?"

"Nope. They're born meat and they die meat. We studied them for several of their life spans, which didn't take too long. Do you have any idea the life span of meat?

"Spare me. Okay, maybe they're only part meat. You know, like the Weddilei. A meat head with an electron plasma brain inside?"

"Nope. We thought of that, since they do have meat heads like the Weddilei. But I told you, we probed them. They're meat all the way through."

"No brain?"

"Oh, there's a brain all right. It's just that the brain is made out of meat!"

"So... what does the thinking?"

"You're not understanding, are you? The brain does the thinking. The meat."

"Thinking meat?!? You're asking me to believe in thinking meat?"

"Yes, thinking meat! Conscious meat! Living meat! Dreaming meat! The meat is the whole deal! Are you getting the picture?!?"

"Omigod. You're serious then. They're made out of meat."

"Finally! Yes! They are indeed made out of meat. And they've been trying to get in touch with us for almost a hundred of their years."

"So what does the meat have in mind?"

"First it wants to talk to us. Then I imagine it wants to explore the universe, contact other sentients, swap ideas and information. The usual."

"We're supposed to talk to meat?"

"That's the idea. That's the message they're sending out by radio. 'Hello. Anyone out there? Anyone home?' That sort of thing."

"They actually do talk, then. They use words, ideas, concepts?"

"Oh, yes. Except they do it with meat."

"I thought you just told me they used radio."

"They do, but what do you think is on the radio? Meat sounds! You know how when you slap or flap meat it makes a noise? They talk by flapping their meat at each other. They can even sing by squirting air thorough their meat."

"Omigod. Singing meat. This is altogether too much. So what do you advise?"

"Officially or unofficially?"

"Both."

"Officially, we are required to contact, welcome, and log in any and all sentient races or multibeings in the quadrant, without prejudice, fear, or favour. Unofficially, I advise that we erase the records and forget the whole thing."

"I was hoping you would say that."

"It seems harsh, but there is a limit. Do we really want to make contact with meat?"

"I agree one hundred percent. What's there to say?" 'Hello, meat. How's it going?' But will this work? How many planets are we dealing with here?"

"Just the one. They can travel to other planets in special meat containers, but they can't live on them. And being meat, they only travel through C space, which limits them to the speed of light and makes the possibility of their ever making contact pretty slim. Infinitesimal, in fact."

"So we just pretend there's no one home in this sector."

"That's it."

"Cruel. But you said it yourself, who wants to meet meat? And the ones who have been aboard our vessels, the ones you have probed? You're sure they won't remember?"

"They'll be considered crackpots if they do. We went into their heads and smoothed out their meat so that we're just a dream to them."

"A dream to meat! How strangely appropriate, that we should be meat's dream."

"And we can mark this sector unoccupied."

"Good. Agreed, officially and unofficially. Case closed. Any others? Anyone interesting on that side of the galaxy?"

"Yes, a rather shy but sweet hydrogen-core cluster intelligence in a class nine star in G445 zone. Was in contact two galactic rotations ago, wants to be friendly again."

"They always come around."

"And why not? Imagine how unbearably, how unutterably cold the universe would be if one were all alone!"

SETI@home sign-up notes

2005-03-21T08:17:28Z

The Radio Astronomy Laboratory at U.C. Berkeley, the group that administers the SETI@home program, has been experiencing power and hardware problems over the past two weeks. This has prevented access to many, and at times, all of their servers. In turn, that has prevented or curtailed potentially new users from signing-up to participate. And for those already in the program, it's been very difficult to return work sets, and download new ones.

Given these problems, now might not be the best time to join the SETI@home program; even when they're up, the servers are being over-taxed in an attempt to catch-up with the outstanding work.

Hopefully these problems will be resolved sometime this week. I suggest you monitor the Tech News page at http://setiweb.ssl.berkeley.edu/tech_news.php and the Server/Database Status page at http://setiweb.ssl.berkeley.edu/sah_status.html for signs of an up and running system before attempting to join; to do otherwise is just an invitation to frustration!

Once these problems have been resolved, and the system is stable, please visit http://setiweb.ssl.berkeley.edu/create_account_form.php?teamid=114944 to create an account and sign-up as a member of tribe.net's team. After that is done you should visit http://setiweb.ssl.berkeley.edu/ to download the BOINC software and access other SETI@home links.

that search the universe for signs of intelligent life using the electromagnetic spectrum is like searching the universe for a really good italian restaraunt?

that about sums it up, i think

besides, why search out there for something that is already here?

bring on the ridicule :)
