A faint pair of stars, 220 trillion miles away, has been tentatively identified as the "home base" of intelligent extraterrestrials who allegedly visited Earth in 1961. This hypothesis is based on a strange, almost bizarre series of events mixing astronomical research with hypnosis, amnesia, and alien humanoid creatures. The two stars are known as Zeta 1 and Zeta 2 Reticuli, or together as simply Zeta Reticuli. They are each fifth magnitude stars -- barely visible to the unaided eye -- located in the obscure souther constellation Reticulum. This southerly sky location makes Zeta Reticuli invisible to observers north of Mexico City's latitude. The weird circumstances that we have dubbed "The Zeta Reticuli Incident" sound like they come straight from the UFO pages in one of those tabloids sold in every supermarket. But this is much more than a retelling of a famous UFO incident; it's an astronomical detective story that at times hovers on that hazy line that separates science from fiction. It all started this way: The date is Sept. 19, 1961. A middle aged New Hampshire couple, Betty and Barney Hill, are driving home from a short vacation in Canada. It's dark, with the moon and stars illuminating the wooded landscape along U.S. Route 3 in central New Hampshire. The Hills' curiosity is aroused when a bright "star" seems to move in an irregular pattern. They stop the car for a better view. The object moves closer, and its disklike shape becomes evident. Barney grabs his binoculars from the car seat and steps out. He walks into a field to get a closer look, focuses the binoculars, and sees the object plainly. It has windows -- and behind the windows, looking directly at him are...humanoid creatures! Terrified, Barney stumbles back to the car, throws it into first gear and roars off. But for some reason he turns down a side road where five of the humanoids are standing on the road. Apparently unable to control their actions, Betty and Barney are easily taken back to the ship by the humanoids. While inside they are physically examined, and one of the humanoids communicates to Betty. After the examination she asks him where they are from. In response he shows her a three-dimensional map with various sized dots and lines on it. "Where are you on the map?" the humanoid asks Betty. She doesn't know, so the subject is dropped. Betty and Barney are returned unharmed to their car. They are told they will forget the abduction portion of the incident. The ship rises, and then hurtles out of sight. The couple continue their journey home oblivious of the abduction. But the Hills are troubled by unexplained dreams and anxiety about two hours of their trip that they can't account for. Betty, a social worker, asks advice from a psychiatrist friend. He suggests that the memory of that time will be gradually restored over the next few months -- but it never is. Two years after the incident, the couple are still bothered by the missing two hours, and Barney's ulcers are acting up. A Boston psychiatrist, Benjamin Simon, is recommended, and after several months of weekly hypnosis sessions the bizarre events of that night in 1961 are revealed. A short time later a UFO group leaks a distorted version of the story to the press and the whole thing blows up. The Hills reluctantly disclose the entire story. Can we take this dramatic scenario seriously? Did this incredible contact with aliens actually occur or is it some kind of hallucination that affected both Barney and Betty Hill? The complete account of the psychiatric examination from which the details of the event emerged is related in John G. Fuller's 'The Interrupted Journey' (Dial Press, 1966), where we read that after the extensive psychiatric examination, Simon concluded that the Hills were not fabricating the story. The most likely possibilities seem to be: (a) the experience actually happened, or (b) some perceptive and illusory misinterpretations occurred in relationship to some real event. There are other cases of alleged abductions by extraterrestrial humanoids. The unique aspect of the Hills' abduction is that they remembered virtually nothing of the incident. Intrigued by the Hills' experience, J. Allen Hynek, chairman of the department of astronomy at Northwestern University, decided to investigate. Hynek described how the Hills recalled the details of their encounter in his book, 'The UFO Experience' (Henry Regnery Company, 1972): "Under repeated hypnosis they independently revealed what had supposedly happened. The two stories agreed in considerable detail, although neither Betty nor Barney was privy to what the other had said under hypnosis until much later. Under hypnosis they stated that they had been taken separately aboard the craft, treated well by the occupants -- rather as humans might treat experimental animals -- and then released after having been given the hypnotic suggestion that they would remember nothing of that particular experience. The method of their release supposedly accounted for the amnesia, which was apparently broken only by counterhypnosis." A number of scientists, including Hynek, have discussed this incident at length with Barney and Betty Hill and have questioned them under hypnosis. They concur with Simon's belief that there seems to be no evidence of outright fabrication or lying. One would also wonder what Betty, who has a master's degree in social work and is a supervisor in the New Hampshire Welfare Department, and Barney, who was on the governor of New Hampshire's Civil Rights Commission, would have to gain by a hoax? Although the Hills didn't, several people have lost their jobs after being associated with similarly unusual publicity. Stanton T. Friedman, a nuclear physicist and the nation's only space scientist devoting full time to researching the UFO phenomenon, has spent many hours in conversation with the Hills. "By no stretch of the imagination could anyone who knows them conclude that they were nuts," he emphasizes. So the experience remains a fascinating story despite the absence of proof that it actually happened. Anyway -- that's where things were in 1966 when Marjorie Fish, an Ohio schoolteacher, amateur astronomer and member of Mensa, became involved. She wondered if the objects shown on the map that Betty Hill allegedly observed inside the vehicle might represent some actual pattern of celestial objects. To get more information about the map she decided to visit Betty Hill in the summer of 1969. (Barney Hill died in early 1969.) Here is Ms. Fish's account of that meeting: According to the most recent star catalogs, there are about 1,000 known stars within a radius of 55 light-years of the sun. What are those other stars like? A check of the catalogs shows that most of them are faint stars of relatively low temperature -- a class of stars astronomers call main sequence stars. The sun is a main sequence star along with most of the other stars in this part of the Milky Way galaxy, as the following table shows: Main sequence stars 91% White dwarfs 8% Giants and Supergiants 1% Typical giant stars are Arcturus and Capella. Antares and Betelgeuse are members of the ultrarare supergiant class. At the other end of the size and brightness scale the white dwarfs are stellar cinders -- the remains of once brilliant suns. For reasons that will soon become clear we can remove these classes of stars from our discussion and concentrate on the main sequence stars. The main sequence stars can be further subdivided. Characteristics of Main Sequence Stars Class Proportion of Total Temperature (Degrees F) Mass (Sun=1) Luminosity (Sun=1) Lifespan (billions yrs) - A0 1% 20,000 2.8 60 5 Vega A5 - 15,000 2.2 20 1 - F0 3% 13,000 1.7 6 2 Procyon F5 - 12,000 1.25 3 4 - G0 9% 11,000 1.06 1.3 10 Sun G5 - 10,000 .92 .8 15 - K0 14% 9,000 .8 .4 20 Epsilon Erandi K5 - 8,000 .69 .1 30 - M0 73% 7,000 .48 .02 75 Proxima Centauri M5 - 5,000 .2 .001 200 - The spectral class letters are part of a system of stellar "fingerprinting" that identifies the main sequence star's temperature and gives clues to its mass and luminosity. The hottest, brightest and most massive main sequence stars (with rare exceptions) are the A stars. The faintest, coolest and least massive are the M stars. Each class is subdivided into 10 subcategories. For example, an A0 star is hotter, brighter and more massive than an A1 which is above an A2, and so on through A9. This table supplies much additional information and shows how a slightly hotter and more massive star turns out to be much more luminous than the sun, a G2 star. But the bright stars pay dearly for their splendor. It takes a lot of stellar fuel to emit vast quantities of light and heat. The penalty is a short lifespan as a main sequence star. Conversely, the inconspicuous, cool M stars may be around to see the end of the universe -- whatever that might be. With all these facts at hand we're now ready to tackle the first part of the detective story. Let's suppose we wanted to make our own map of a trip to the stars. We will limit ourselves to the 55 light-year radius covered by the detailed star catalogs. The purpose of the trip will be to search for intelligent life on planets that may be in orbit around these stars. We would want to include every star that would seem likely to have a life-bearing planet orbiting around it. How many of these thousand-odd stars would we include for such a voyage and which direction would we go? (For the moment, we'll forget about the problem of making a spacecraft that will take us to these stars and we'll assume that we've got some kind of vehicle that will effortlessly transport us to wherever we want to go.) We don't want to waste our time and efforts -- we only want to go to stars that we would think would have a high probability of having planets harboring advanced life forms. This seems like a tall order. How do we even begin to determine which stars might likely have such planets? The first rule will be to restrict ourselves to life as we know it, the kind of life that we are familiar with here on Earth -- carbon based life. Science fiction writers are fond of describing life forms based on chemical systems that we have been unable to duplicate here on Earth -- such as silicon based life or life based on the ammonium hydroxide molecule instead of on carbon. But right now these life forms are simply fantasy -- we have no evidence that they are in fact possible. Because we don't even know what they might look like -- if they're out there -- we necessarily have to limit our search to the kind of life that we understand. Our kind of life -- life as we know it -- seems most likely to evolve on a planet that has a stable temperature regime. It must be at the appropriate distance from its sun so that water is neither frozen nor boiled away. The planet has to be the appropriate size so that its gravity doesn't hold on to too much atmosphere (like Jupiter) or too little (like Mars). But the main ingredient in a life-bearing planet is its star. And its star is the only thing we can study since planets of other stars are far too faint to detect directly. The conclusion we can draw is this: The star has to be like the sun. Main sequence stars are basically stable for long periods of time. As shown in the table, stars in spectral class G have stable lifespans of 10 billion years. (Our sun, actually a G2 star, has a somewhat longer stable life expectancy of 11 billion years.) We are about five billion years into that period so we can look forward to the sun remaining much as it is (actually it will brighten slightly) for another six billion years. Stars of class F4 or higher have stable burning periods of less than 3.5 billion years. They have to be ruled out immediately. Such stars cannot have life-bearing planets because, at least based on our experience on our world, this is not enough time to permit highly developed biological systems to evolve on the land areas of a planet. (Intelligent life may very well arise earlier in water environments, but let's forget that possibility since we have not yet had meaningful communication with the dolphins -- highly intelligent creatures on this planet!) But we may be wrong in our estimate of life development time. There is another more compelling reason for eliminating stars of class F4 and brighter. So far, we have assumed all stars have planets, just as our sun does. Yet spectroscopic studies of stars of class F4 and brighter reveal that most of them are in fact unlike our sun in a vital way -- they are rapidly rotating stars. The sun rotates once in just under a month, but 60 percent of the stars in the F0 to F4 range rotate much faster. And almost all A stars are rapid rotators too. It seems, from recent studies of stellar evolution that slowly rotating stars like the sun rotate slowly because they have planets. Apparently the formation of a planetary system robs the star of much of its rotational momentum. For two reasons, then, we eliminate stars of class F4 and above: (1) most of them rotate rapidly and thus seem to be planetless, and (2) their stable lifespans are too brief for advanced life to develop. Another problem environment for higher forms of life is the multiple star system. About half of all stars are born in pairs, or small groups of three or more. Our sun could have been part of a double star system. If Jupiter was 80 times more massive it would be an M6 red dwarf star. If the stars of a double system are far enough apart there is no real problem for planets sustaining life (see "Planet of the Double Sun", September 1974). But stars in fairly close or highly elliptical orbits would alternately fry or freeze their planets. Such planets would also likely have unstable orbits. Because this is a potentially troublesome area for our objective, we will eliminate all close and moderately close pairs of systems of multiple stars. Further elimination is necessary according to the catalogs. Some otherwise perfect stars are labeled "variable". This means astronomers have observed variations of at least a few percent in the star's light output. A one percent fluctuation in the sun would be annoying for us here on Earth. Anything greater would cause climatic disaster. Could intelligent life evolve under such conditions, given an otherwise habitable planet? It seems unlikely. We are forced to "scratch" all stars suspected or proven to be variable. Route map. Click here. The route map above shows the culmination of our efforts. This group of stars is a "natural" for exploration when we achieve interstellar flight. Even if, as most exobiologists contend, we are highly unlikely to find advanced forms of life in such a small sample, the physical exploration of planets of other stars by beings from Earth is inevitable, and the stars of this group should be among the first targets. Now we are ready to return to the map drawn by Betty Hill. Marjorie Fish reasoned that if the stars in the Hill map corresponded to a patter of real stars -- perhaps something like we just developed, only from an alien's viewpoint -- it might be possible to pinpoint the origin of the alleged space travelers. Assuming the two stars in the foreground of the Hill map were the "base" stars (the sun, a single star, was ruled out here), she decided to try to locate the entire pattern. She theorized that the Hill map contained only local stars since no concentration would be present if a more distant viewpoint was assumed and if both "us" and the alien visitors' home base were to be represented. Let's assume, just as an astronomical exercise, that the map does show the sun and the star that is "the sun" to the humanoids. We'll take the Hill encounter at face value, and see where it leads. Since the aliens were described as "humanoid" and seemed reasonably comfortable on this planet, their home planet should be basically like ours. Their atmosphere must be similar because the Hills breathed without trouble while inside the ship, and the aliens did not appear to wear any protective apparatus. And since we assume their biology is similar to ours, their planet should have the same temperature regime as Earth (Betty and Barney did say it was uncomfortably cold in the ship). In essence, then, we assume their home planet must be very Earthlike. Based on what we discussed earlier it follows that their sun would be on our list if it were within 55 light-years of us. The lines on the map, according to Betty Hill, were described by the alien as "trade routes" or "places visited occasionally" with the dotted lines as "expeditions". Any interpretation of the Betty Hill map must retain the logic of these routes (i.e. the lines would link stars that would be worth visiting). The Fish Model. Click here. This model, prepared by Marjorie Fish. shows all the stars located in a vast volume of space extending out about 55 light years in the direction of Zeta Reticuli. The viewing angle is from a point in space beyond that limit looking back toward the Sun. Each star is suspended on a separate thread at its appropriate distance and position from the Sun, and colored according to its spectral type (solar type stars are yellow). The star "behind" the two components of Zeta Reticuli is Zeta Tucanae. From a model such as this, using the same viewing angle seen here, Marjorie Fish noted 16 stars whose positions are remarkably closeto the stars in the drawing made by Betty Hill. The fact that all of the stars in the "Hill configuration" are solar type stars is one of several intriguing areas that enshroud the "Zeta Reticuli Incident". Keeping all this in mind, Marjorie Fish constructed several three-dimensional models of the solar neighborhood in hopes of detecting the pattern in the Hill map. Using beads dangling on threads, she painstakingly recreated our stellar environment. Between Aug. 1968 and Feb. 1973, she strung beads, checked data, searched and checked again. A suspicious alignment, detected in late 1968, turned out to be almost a perfect match once new data from the detailed 1969 edition of the Catalog of Nearby Stars became available. (This catalog is often called the "Gliese catalog" -- pronounced "glee-see" -- after its principal author, Wilhelm Gliese.) The 16 stars in the stellar configuration discovered by Marjorie Fish are compared with the map drawn by Betty Hill in the diagram on page 6. If some of the star names on the Fish map sound familiar, they should. Ten of the 16 stars are from the compact group that we selected earlier based on the most logical direction to pursue to conduct interstellar exploration from Earth Continuing to take the Hill map at face value, the radiating pattern of "trade routes" implies that Zeta 1 and Zeta 2 Reticuli are the "hub" of exploration or, in the context of the incident, the aliens' home base. The sun is at the end of one of the supposedly regular trade routes. The pair of stars that make up Zeta Reticuli is practically in the midst of the cluster of solar type stars that attracted us while we were mapping out a logical interstellar voyage. Checking further we find that all but two of the stars in the Fish pattern are on the table of nearby solar type stars. These two stars are Tau 1 Eridani (an F6 star) and Gliese 86.1 (K2), and are, respectively, just above and below the parameters we arrived at earlier. One star that should be there (Zeta Tucanae) is missing probably because it is behind Zeta 1 Reticuli at the required viewing angle. To summarize, then: (1) the pattern discovered by Marjorie Fish has an uncanny resemblance to the map drawn by Betty Hill; (2) the stars are mostly the ones that we would visit if we were exploring from Zeta Reticuli, and (3) the travel patterns generally make sense. Walter Mitchell, professor of astronomy at Ohio State University in Columbus, has looked at Marjorie Fish's interpretation of the Betty Hill map in detail and tells u… truncated (9,545 more characters in archive)
