    The search for alien technology is about to get much more efficient. No image credit.

    I’ve bet a cup of coffee to any and all that by 2035 we’ll have evidence of E.T. To many of my colleagues, that sounds like a losing proposition. For more than a half-century, a small coterie of scientists has been pursuing the Search for Extraterrestrial Intelligence, or SETI. And we haven’t found a thing.

    I’m optimistic by nature—as a scientist, you have to be. But my hopeful feeling is not wishful thinking; it is firmly grounded in the logic of SETI.

    Half a century sounds like a long time, but the search is truly in its early days. Given the current state of SETI efforts and abilities, I feel that we’re on the cusp of learning something truly revolutionary.

    Most of our experiments so far have used large radio antennas in an effort to eavesdrop on radio signals transmitted by other societies, an approach that was dramatized by Jodie Foster in the 1997 movie Contact.

    Unlike other alien potboilers, Contact’s portrayal of how we might search for extraterrestrials was reasonably accurate. Nonetheless, that film reinforced the common belief that SETI practitioners paw through cosmic static looking for unusual patterns, such as a string of prime numbers. The truth is simpler: We have been searching for narrow-band signals. “Narrow-band” means that a large fraction of the transmitter power is squeezed into a tiny part of the radio dial, making the transmission easier to find. This is analogous to the way a laser pointer, despite having only a few milliwatts of power, nonetheless looks bright because the energy is concentrated into a narrow wavelength range.

    A modern SETI receiver simultaneously examines tens or even hundreds of millions of channels, each having a cramped 1-hertz bandwidth. That bandwidth is 5 million times narrower than a TV signal and lacks the capacity to carry information—a message. But the idea is to first discover aliens that are on the air, after which a far larger instrument would be built to dig out any modulation.

    To aim our antennas, SETI has traditionally used two approaches. One is to scan as much of the sky as possible; the other is to zero in on nearby star systems. You might think that the former would have an edge, since it makes no assumptions about where the aliens might be hanging out. But a sky survey spends most of its time looking at empty space. If you subscribe to the conventional view that extraterrestrials will most likely be ensconced on planets or moons, then it’s better to devote precious telescope time to examining nearby star systems.

    One current targeted search is the SETI Institute’s red dwarf survey, which takes place at the Allen Telescope Array, an ensemble of 42 antennas hunkered down in the California Cascades.

    We are going down a list of 20,000 small stars that are prime candidates for hosting habitable planets. These ruddy runts are both numerous and, on average, old. Most have been around for billions of years, the time it took life on Earth to evolve from microscopic slime to high-tech hominids. Astronomers estimate that roughly one-half of all red dwarfs might have a rocky world in the habitable zone, where temperatures would abide liquid water.

    The SETI Institute is not the only band of alien hunters. Buoyed by a large infusion of money from the Russian billionaire Yuri Milner, the SETI group at the University of California, Berkeley, is renting time on the Green Bank Telescope in West Virginia and the Parkes Radio Telescope in the sheep country west of Sydney, Australia. Their decade-long project, known as Breakthrough Listen, also homes in on individual star systems.

    Astronomers are expanding the search for extraterrestrial intelligence into a new realm with detectors tuned to infrared light at UC’s Lick Observatory. A new instrument, called NIROSETI, will soon scour the sky for messages from other worlds.

    “Infrared light would be an excellent means of interstellar communication,” said Shelley Wright, an assistant professor of physics at UC San Diego who led the development of the new instrument while at the University of Toronto’s Dunlap Institute for Astronomy & Astrophysics.

    Wright worked on an earlier SETI project at Lick Observatory as a UC Santa Cruz undergraduate, when she built an optical instrument designed by UC Berkeley researchers. The infrared project takes advantage of new technology not available for that first optical search.

    Infrared light would be a good way for extraterrestrials to get our attention here on Earth, since pulses from a powerful infrared laser could outshine a star, if only for a billionth of a second. Interstellar gas and dust is almost transparent to near infrared, so these signals can be seen from great distances. It also takes less energy to send information using infrared signals than with visible light.

    Frank Drake, professor emeritus of astronomy and astrophysics at UC Santa Cruz and director emeritus of the SETI Institute, said there are several additional advantages to a search in the infrared realm.

    “The signals are so strong that we only need a small telescope to receive them. Smaller telescopes can offer more observational time, and that is good because we need to search many stars for a chance of success,” said Drake.

    The only downside is that extraterrestrials would need to be transmitting their signals in our direction, Drake said, though he sees this as a positive side to that limitation. “If we get a signal from someone who’s aiming for us, it could mean there’s altruism in the universe. I like that idea. If they want to be friendly, that’s who we will find.”

    Scientists have searched the skies for radio signals for more than 50 years and expanded their search into the optical realm more than a decade ago. The idea of searching in the infrared is not a new one, but instruments capable of capturing pulses of infrared light only recently became available.

    “We had to wait,” Wright said. “I spent eight years waiting and watching as new technology emerged.”

    Now that technology has caught up, the search will extend to stars thousands of light years away, rather than just hundreds. NIROSETI, or Near-Infrared Optical Search for Extraterrestrial Intelligence, could also uncover new information about the physical universe.

    “This is the first time Earthlings have looked at the universe at infrared wavelengths with nanosecond time scales,” said Dan Werthimer, UC Berkeley SETI Project Director. “The instrument could discover new astrophysical phenomena, or perhaps answer the question of whether we are alone.”

    NIROSETI will also gather more information than previous optical detectors by recording levels of light over time so that patterns can be analyzed for potential signs of other civilizations.

    “Searching for intelligent life in the universe is both thrilling and somewhat unorthodox,” said Claire Max, director of UC Observatories and professor of astronomy and astrophysics at UC Santa Cruz. “Lick Observatory has already been the site of several previous SETI searches, so this is a very exciting addition to the current research taking place.”

    NIROSETI will be fully operational by early summer and will scan the skies several times a week on the Nickel 1-meter telescope at Lick Observatory, located on Mt. Hamilton east of San Jose.

    The NIROSETI team also includes Geoffrey Marcy and Andrew Siemion from UC Berkeley; Patrick Dorval, a Dunlap undergraduate, and Elliot Meyer, a Dunlap graduate student; and Richard Treffers of Starman Systems. Funding for the project comes from the generous support of Bill and Susan Bloomfield.

    While these efforts are broadly similar to what’s been done for decades, they are not your daddy’s SETI. The rapid growth in digital processing means that far larger swaths of the radio dial can be examined at one go and—in the case of the Allen array—many star systems can be checked out simultaneously. The array now examines three stars at once, but additional computer power could boost that to more than 100. Within two decades, SETI experiments will be able to complete a reconnaissance of 1 million star systems, which is hundreds of times more than have been carefully examined so far. SETI practitioners from Frank Drake to Carl Sagan have estimated that the galaxy currently houses somewhere between 10,000 and a few million broadcasting societies.

    If these estimates are right, then examining 1 million star systems could well lead to a discovery. So, if the premise of SETI has merit, we should find a broadcast from E.T. within a generation. That would spare me the expense of buying you a cup of coffee.

    Furthermore, scientists have been diversifying. For two decades, some SETI researchers have used conventional optical telescopes to look for extremely brief laser flashes coming from the stars. In many ways, aliens might be more likely to communicate by pulsed light than radio signals, for the same reason that people are turning to fiber optics for Internet access: It can, at least in principle, send 100,000 times as many bits per second as radio can. These so-called optical SETI experiments have been limited to looking at one star system at a time. But like their radio cousins, they’re poised to become speedier as new technology allows them to survey ever-wider tracts of sky.

    Physicists have also proposed wholly new modes of communications, such as neutrinos and gravitational waves. Some of my SETI colleagues have mulled these options, but we don’t see much merit in them at the moment. Both neutrinos and gravitational waves are inherently hard to create and detect. In nature, it takes the collapse of a star or the merger of black holes to produce them in any quantity. The total energy required to send “Hello, Earth” would be daunting, even for a civilization that could command the resources of a galaxy.

    IceCube, the University of Wisconsin’s big neutrino detector in Antarctica, is sensitive only to very high-energy particles, which are precisely those that would be costliest to produce.

    In all the years it has been operating, the instrument has detected a total of a few dozen of these particles, even though it is a cubic kilometer in size. As for gravitational waves, the Laser Interferometric Gravitational-Wave Observatory has been able to detect colliding black holes over the final second of their infall.

    It is hard to imagine that aliens would go to the trouble of smashing together two huge black holes for a second’s worth of signal.

    But there is a completely different approach that has yet to be explored in much detail: to look for artifacts—engineering projects of an advanced society. Some astronomers have suggested an alien megastructure, possibly an energy-collecting Dyson sphere, as the explanation for the mysterious dimming of Tabby’s star (officially known as KIC 8462852). It is a serious possibility, but no evidence has yet been found to support it.

    It’s also conceivable that extraterrestrials could have left time capsules in our own solar system, perhaps millions or billions of years ago, on the assumption that our planet might eventually evolve a species able to find them. The Lagrange points in the Earth-moon system—locations where the gravity of Earth, moon, and sun are balanced, so that an object placed there will stay there—have been suggested as good hunting grounds for alien artifacts, as has the moon itself.

    LaGrange Points map. NASA

    Another idea is that we should search for the high-energy exhausts of interstellar rockets. The fastest spacecraft would presumably use the most efficient fuel: matter combining with antimatter. Their destructive “combustion” would not only shoot the craft through space at a fair fraction of the speed of light, but would produce a gamma-ray exhaust, which we might detect. Rockets could be sorted out from natural gamma ray sources by their relatively quick motion across the sky.

    The appealing thing about artifacts is that finding them is not time-critical. In contrast, to search for signals, you need to activate your instruments at the right time. It doesn’t help to look for radio pings, laser flashes, or neutrino bursts if E.T. reached out to touch us during the reign of the dinosaurs or will do so a hundred million years from now. Artifacts have no such synchronicity problem. That said, looking for artifacts has its own bummer factors. Anything beyond our solar system would need be truly huge to be visible; cousins of the starship Enterprise would be very difficult to find.

    SETI is not a traditional science problem in which a hypothesis can be falsified. We can never prove that the aliens are not out there, only that they are. But our ability to search improves with every technological innovation. I compare the situation to the year 1491. European civilization had been around for 2,500 years, yet the Americas were not on any map. Mesoamerican civilization, for its part, had been around for about as long, but also was ignorant of what lay over the oceans. With a glimpse and a shout from a sailor on the Pinta, everything changed.

    Jill Tarter is the subject of a new book by Sarah Scoles, Making Contact: Jill Tarter and the Search for Extraterrestrial Intelligence, which was released yesterday. Jill is a pioneer in SETI research and currently holds the Bernard M. Oliver Chair at the SETI Institute. Making Contact is not just for scientists and SETI enthusiasts, but truly is the story of Jill’s life and her life’s work.

    “This is one woman’s view of the roller coaster history of SETI explorations,” said Jill. “Sarah has told it with a fresh voice that makes me grin.”

    In Making Contact, Scoles examines the science behind the work that tries to answer the question, “Are we alone?” Jill was the inspiration for the character of Ellie Arroway in Carl Sagan’s Contact, a role played by Jodie Foster in the film, which celebrates its 20th anniversary this month. Scoles tells Jill’s story, and also begins to wonder how a new generation of SETI research will look.

    “A fictional story about SETI, partly inspired by Tarter, has spurred so many people’s interests in astronomy and life in the universe,” said Scoles. “I hope the nonfictional tale of the actual search and the actual Tarter can do something similar.”

    Scoles suggests that without Jill, SETI programs, including the SETI Institute’s Allen Telescope Array (ATA) and Breakthrough Listen might not exist.

    Additionally, funding for SETI research has always been a challenge to obtain. Indeed, the SETI Institute’s own SETI program is funded entirely through private donations and receives no government support. Jill’s ongoing efforts continue to make groundbreaking SETI research possible.

    “Jill is not only a SETI pioneer, and world-class astronomer, her life and work have served as inspiration for an entire new generation of women in science, including many here at the SETI Institute” said Institute CEO, Bill Diamond. “Her toughness, tenacity and perseverance in a male-dominated field of enquiry are fully explored in this captivating biography of a scientist possessed by what is perhaps humankind’s greatest quest – answering that singular question – Are we alone?”

    Jill and Sarah will appear together on July 12 at the Cubberley Community Center in Mountain View, CA to discuss the book and new directions in SETI research. The presentation is part of the SETI Institute’s SETI Talks series and will also feature SETI Institute scientists Eliot Gillum and Seth Shostak. Tickets are available here.

    Over the weekend, astronomers trained their telescopes a relatively close star, hoping for more evidence of a curious signal heard over a year ago by Russian radio telescope operators.

    First detected on May 15, 2015—but only just now reported to other SETI scientists—the 11 GHz signal appears to have originated from HD 164595, a star with 0.99 solar masses and known to have at least one planet orbiting it, a so-called “warm Neptune.”

    The Allen Telescope Array, one of the telescopes now observing HD 164595.

    The frequency of the signal is unlikely to be an astrophysical phenomenon, though scientists have yet to rule out terrestrial interference.

    Here’s Alan Boyle, reporting for GeekWire:

    “At least two SETI research groups are aiming to track HD 164595 tonight. The SETI Institute is using the Allen Telescope Array in northern California, while METI International is looking to the Boquete Optical SETI Observatory in Panama.

    2

    [Centuari Dreams’ author Paul] Gilster reports that the signal spike was detected more than a year ago, on May 15, 2015, by the RATAN-600 radio telescope in Zelenchukskaya. That facility is in the Russian republic of Karachay-Cherkessia, not far from the Georgian border.”

    Doug Vakoch, president of METI International, a SETI-affiliated group, expressed dismay in an email to Boyle that the report took so long to make its way to other scientists, saying that quick communication can help confirm the source or rule out interference. Vakoch’s team is among those now observing the star.

    The high frequency is what’s driving interest in the signal. Here’s Eric Berger, reporting for Ars Technica:

    “If this were a real astronomical source, it would be rather strange,” [astronomer Nick] Suntzeff told Ars. Although there are mysterious, high-energy astrophysical phenomenon called “fast radio bursts” that are seen at a few gigahertz, they last only 10 milliseconds or so (this event lasted longer). Unfortunately, he said, there is no information given about the strength of the signal as a function of frequency.”

    It’s possible that an 11 GHz radio signal could be ground-to-satellite communication or some unknown military transmission.

    For now, given the number of caveats attached to this signal, astronomers are downplaying the possibility of extraterrestrial life.

    Some recent articles in the press convey the impression that our current efforts to find intelligent life beyond Earth are unlikely to succeed simply because our technology is not advanced enough to sense alien signals.

    Of course, that’s not true. Consider the Allen Telescope Array[ATA], currently being used every day by the SETI Institute in its hunt for signals from other star systems.

    Allen Telescope Array
    ATA

    This instrument is exquisitely sensitive – it could find some of the powerful radars that we have here on Earth at a distance of dozens of light-years. Any society that is even slightly more technically advanced than our own could easily manage a deliberate radio transmission that the Array could pick up. For SETI researchers, it’s a matter of aiming our antennas in the right direction, and tuning to the correct spot on the dial.

    But could it be that our incomplete understanding of physics is keeping us from finding the extraterrestrials? Perhaps they don’t use radio, but have moved on to some hypothetical new communication mode. Of course that’s possible, but it’s at least as probable that radio and light are – and always will be – the most efficient method of sending bits of information from one star system to another.

    In any case, the possibility of “new physics” invalidating today’s SETI experiments is an indefensible reason to abandon the search. One might have pointed out to Columbus that wooden ships were a poor way to traverse an ocean, and he should just wait for aviation. But the wooden ships were good enough.

    Our SETI technology will, of course, improve with time. Nonetheless, the discovery of a signal betraying extraterrestrial intelligence could still happen today, tomorrow, or next week. But only if we search.

    From SETI: “No Signals from Newest Kepler Planet” 


    SETI Institute

    Jan 7, 2015

    SETI Seth Shostak
    By Seth Shostak, Senior Astronomer and Director of SETI Research

    A newly discovered planet has been observed with the Allen Telescope Array in a search for radio signals that would betray technically sophisticated inhabitants, but no transmissions have been detected.

    Allen Telescope Array
    Allen Telescope Array

    The planet is known as Kepler 116454b, and orbits an orange dwarf star in the constellation Pisces. It is 180 light-years away.

    Jon Richards, of the SETI Institute’s Center for SETI Research, used the Allen Telescope Array to look for signals over the frequency range of 1000 – 2250 MHz.

    In May, 2013 the Kepler space telescope suffered a mechanical failure that ended its ability to accurately aim at the sky. But the telescope has resumed its search for planets in a new mode, using the pressure of sunlight to help it steady its gaze on the sky. Kepler 116454b is the first planet to be found by the reincarnated telescope, and its discovery was announced just before Christmas.

    NASA Kepler Telescope

    The planet orbits its home star in 9 days in an orbit three times smaller than Mercury’s orbit around the Sun. Consequently, temperatures on this world – which is a so-called “super Earth” and larger than Earth but smaller than Neptune – are expected to be too hot for life as we know it.

    Nonetheless, and as centuries of experience have shown, observation sometimes trumps expectation, and that is why new exoplanets – whether they seem promising for life or not – are routinely observed by the SETI Institute with the Allen Telescope Array.

    The observations of Kepler 116454b will continue at higher frequencies, Richards notes.

    From SETI Institute: Meet Dr Jill Tarter 

    Jill Tarter is my candidate for Miss Universe.

    i1

    “Astronomer Dr. Jill Tarter is Director of the Institute’s Center for SETI Research, and also holder of the Bernard M. Oliver Chair for SETI (Search for Extraterrestrial Intelligence). She is one of the few researchers to have devoted her career to hunting for signs of sentient beings elsewhere, and there are few aspects of this field that have not been affected by her work. Jill was the lead for Project Phoenix, a decade-long SETI scrutiny of about 750 nearby star systems, using telescopes in Australia, West Virginia and Puerto Rico. While no clearly extraterrestrial signal was found, this was the most comprehensive targeted search for artificially generated cosmic signals ever undertaken. Among her numerous distinguished awards and recognitions, Jill received the 2009 TED Prize, which will empower Jill and her team to take SETI research to an entirely new and broader level.

    Being as much of an icon of SETI as Jill is, perhaps it is not surprising that the Jodie Foster character in the movie Contact is largely inspired by this real-life researcher.”

    Now, the above is from Jill’s bio interview page at the SETI Institute web site. There is much more, so you should go there and read it.

    I went looking for more just plain facts. Usually, Wikipedia is a sure bet. Not this time. Short and sweet. Not even much of Jill’s CV. But, at SETI Institute, there is a really good listing of Jill’s accomplishments. Check it out.
