    The Robert C. Byrd Radio Telescope at the Green Bank Observatory in West Virginia is one of the primary receivers looking for promising SETI signals.

    The Search for Extraterrestrial Intelligence (SETI) has been going for nearly 60 years now, and there have been plenty of false alarms in that time and nothing substantial. Now, a giant SETI initiative is looking into its initial round of data to follow up on 11 signals that they think could be aliens … but admit probably aren’t. Good to check, though, just in case.

    Two years ago, billionaire Yuri Milner put $100 million into a decade-long search for aliens known as the Breakthrough Listen initiative. It was the widest-scale SETI project announced since Project Phoenix in 1995, which itself was the successor of a cancelled 10 year, $100 million SETI effort by NASA.

    Breakthrough Listen is spearheaded by SETI Berkeley and taps into the wider SETI community to listen in worldwide for radio signals that might be artificial. They’ve also opened up the data to the public at large to look for narrowband signals — those in a specific wavelength that are more likely to be from a non-natural source. There are 692 targets in the initial rounds of data.

    The news is coming out of a two-day conference in California from the Breakthrough Initiatives organization, which is also sponsoring Breakthrough Starshot, a project based on using laser propulsion to power tiny spacecraft to the Alpha Centauri system (specifically Proxima Centauri) in a matter of decades.

    A live broadcast will take place today on Facebook at 6:10 p.m. EST (3:10 p.m. PST) with Andrew Siemion of SETI Berkeley discussing the initial results. You can watch it here.

    Nestled in the hills in Pocahontas County, West Virginia, is the Green Bank Telescope. At 485 feet tall and about 300 feet across, it’s the largest fully-steerable telescope in the world, and it belongs to Green Bank Observatory.

    Since the observatory opened in 1957, researchers have used the facility to make several discoveries, like organic prebiotic molecules — the building blocks of life. The Green Bank Telescope is also one of only two radio telescopes in the world searching for signs of intelligent life in space.

    Breakthrough Listen

    Breakthrough Listen is the largest ever scientific research program aimed at finding evidence of civilizations beyond Earth. The scope and power of the search are on an unprecedented scale:

    The program includes a survey of the 1,000,000 closest stars to Earth. It scans the center of our galaxy and the entire galactic plane. Beyond the Milky Way, it listens for messages from the 100 closest galaxies to ours.

    The instruments used are among the world’s most powerful. They are 50 times more sensitive than existing telescopes dedicated to the search for intelligence.

    The radio surveys cover 10 times more of the sky than previous programs. They also cover at least 5 times more of the radio spectrum – and do it 100 times faster. They are sensitive enough to hear a common aircraft radar transmitting to us from any of the 1000 nearest stars.

    The GBT plays a key role in the Breakthough Listen project, and roughly 20% of the time available on the GBT is dedicated to this research.

    Breakthrough Listen is also carrying out the deepest and broadest ever search for optical laser transmissions. These spectroscopic searches are 1000 times more effective at finding laser signals than ordinary visible light surveys. They could detect a 100 watt laser (the energy of a normal household bulb) from 25 trillion miles away.

    Listen combines these instruments with innovative software and data analysis techniques.

    The initiative will span 10 years and commit a total of $100,000,000.

    More information on Breakthrough Listen is available at https://breakthroughinitiatives.org/Initiative/1

    But today, the telescope and the facility that supports it are under federal review — with the possibility of losing funding or being dismantled.

    In the face of that threat, one West Virginia family hopes to convince the powers that be of the facility’s value to science, education and the small town in which the telescope resides.

    “It’s almost like a tiny metropolitan city in the middle of rural West Virginia,” said Ellie White, a 16-year-old from Barboursville, West Virginia. “That kind of resource is invaluable for kids across the state and across the country, who are going to be tomorrow’s innovators, engineers, scientists, politicians, artists.”

    White’s family volunteered to start a campaign called Go Green Bank Observatory to rally support from across the country and show the National Science Foundation, which used to almost completely fund the observatory, that Green Bank Observatory is worth keeping. In 2012, the NSF published a portfolio review that recommended at least partially divesting from several observatories around the country that no longer have as large of a scientific impact as they used to. Green Bank Observatory was on that list.

    Proposed operational changes for Green Bank Observatory range from continuing to partially fund its operations to shutting down its research operations and turning it into a technology park, or completely tearing it down.

    “This is one of the difficult things the NSF has to do,” said Edward Ahjar, an astronomer at the NSF. “All of our facilities do great science, and that’s why we fund them. But when we start having less and less money to spread around, then we have to prioritize them. Which are doing the most important science now? Which are lower ranked?”

    The Fight to Keep Green Bank Observatory Open

    Last fall, Go Green Bank Observatory encouraged fans to speak at two public scoping meetings where Ahjar and other representatives from the NSF would be present to hear the public’s input about the divestment process.

    About 350 people filled the seats of an auditorium at the observatory. Several in attendance were affiliated with West Virginia University, which since 2006 has received more than $14.5 million in grant dollars for research related to the Green Bank Telescope.

    “When I started applying for graduate school, WVU was one of my top choices,” said Kaustubh Rajwade, a graduate student from India in the Department of Physics and Astronomy at WVU. “The only reason I came here was so I could use the Green Bank Telescope.”

    Others, like Buster Varner, a local fire chief, were more concerned about Green Bank Observatory’s role in the community as a de facto community center, where people can hold meetings and classes.

    “Whenever we had a catastrophe, we can go to Mike,” Varner said, referring to Mike Holstine, the business manager at Green Bank Observatory. “I don’t know much about this science, and there’s a lot of people here who does and that’s great. But I do not want anything to happen to this facility, period.”

    The NSF once almost completely funded Green Bank Observatory’s operations. But Holstine said that especially in the past five years, the observatory saw a need to diversify its sources of funding — in part because outside organizations and researchers expressed a willingness to pay for time on the telescope, but also due to the clear indicators that the observatory needed to rely less on the NSF.

    Green Bank Observatory employs between 100 and 140 people — more than half of whom are from Pocahontas County — depending on the time of year. The money also helps the observatory maintain its own infrastructure in an isolated and rural area.

    “You kind of need to think of us as a town, a self-contained town,” Holstine explained. “We have our own roads. We have our own water system. We have our own wastewater system. We take care of our own buildings. We mow our own grass; we cut our own trees. We have to plow snow in the winter.”

    A Future Without Green Bank Observatory

    For White, the Observatory isn’t only worth keeping because of its accomplishments — but also because of its efforts to train the next generation of scientists. When she was younger, White was convinced she wanted to be an artist when she grew up. But since playing among the telescopes as a child, she has gone on to work on projects under the mentorship of astronomers and graduate students from all over the world.

    She’s not the only teen who’s been impacted by the observatory’s work; through the Pulsar Search Collaboratory, more than 2,000 high school students have worked with the Green Bank Observatory through a partnership with West Virginia University since 2007.

    “Just generally being here, you learn something every day. It’s like learning a new language through immersion,” White said.

    The NSF will reach its decision about the Green Bank Observatory’s fate by the end of this year or the beginning of next year. At 16 years old, White hopes to get her doctorate in astrophysics and one day find full employment at the observatory. If it shuts down, White said, she might have to look for employment out of state.

    From Astronomy Now: “Breakthrough Listen searches new-found nearby planet Proxima b for signs of ET”

    Breakthrough Listen, the 10-year, $100-million astronomical search for intelligent life beyond Earth launched in 2015 by Internet entrepreneur Yuri Milner and Stephen Hawking, today announced its first observations using the Parkes Radio Telescope in New South Wales, Australia.

    Parkes joins the Green Bank Telescope (GBT) in West Virginia, USA, and the Automated Planet Finder (APF) at Lick Observatory in California, USA, in their ongoing surveys to determine whether civilisations elsewhere have developed technologies similar to our own.

    Parkes radio telescope is part of the Australia Telescope National Facility, owned and managed by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO).

    Drawing on over nine months of experience in operation of the dedicated Breakthrough Listen instrument at GBT, a team of scientists and engineers from the University of California, Berkeley’s SETI Research Center (BSRC) deployed similar hardware at Parkes, bringing Breakthrough Listen’s unprecedented search tools to a wide range of sky inaccessible from the GBT. The Southern Hemisphere sky is rich with targets, including the centre of our own Milky Way galaxy, large swaths of the galactic plane, and numerous other galaxies in the nearby universe.

    “The Dish” at Parkes played an iconic role in receiving the first deliberate transmissions from the surface of another world, as the astronauts of Apollo 11 set foot on our Moon. Now, Parkes joins once again in expanding human horizons as we search for the answer to one of our oldest questions: Are we alone?

    “The Parkes Radio Telescope is a superb instrument, with a rich history,” said Pete Worden, Chairman of Breakthrough Prize Foundation and Executive Director of the Breakthrough Initiatives. “We’re very pleased to be collaborating with CSIRO to take Listen to the next level.”

    With its new combined all-sky range, superb telescope sensitivity and computing capacity, Breakthrough Listen is the most powerful, comprehensive, and intensive scientific search ever undertaken for signs of intelligent life beyond Earth.

    Moreover, this expansion of Breakthrough Listen’s range follows the announcement on 12 October that it will be joining forces with the new FAST telescope — the world’s largest filled-aperture radio receiver — to coordinate their searches for artificial signals. The two programs will exchange observing plans, search methods and data, including the rapid sharing of promising new signals for additional observation and analysis. The partnership represents a major step toward establishing a fully connected, global search for intelligent life in the universe.

    “The addition of Parkes is an important milestone,” said Yuri Milner, founder of the Breakthrough Initiatives, which include Breakthrough Listen. “These major instruments are the ears of planet Earth, and now they are listening for signs of other civilisations.”

    First light focused on exo-Earth

    After 14 days of commissioning and test observations, first light for Breakthrough Listen at Parkes was achieved on 7 November, with an observation of the newly-discovered Earth-size planet orbiting the nearest star to the Sun. Proxima Centauri, a red dwarf star 4.2 light-years from Earth, is now known to have a planet (“Proxima b”) within its habitable zone — the region where water could exist in liquid form on the planet’s surface. Such “exo-Earths” (habitable zone exoplanets) are among the primary targets for Breakthrough Listen.

    “The chances of any particular planet hosting intelligent life-forms are probably minuscule,” said Andrew Siemion, director of UC Berkeley SETI Research Center. “But once we knew there was a planet right next door, we had to ask the question, and it was a fitting first observation for Parkes. To find a civilisation just 4.2 light-years away would change everything.”

    As the closest known exoplanet, Proxima b is also the current primary target for Breakthrough Listen’s sister initiative, Breakthrough Starshot, which is developing the technology to send gram-scale spacecraft to the nearest stars.

    “Parkes is one of the most highly cited radio telescopes in the world, with a long list of achievements to its credit, including the discovery of the first ‘fast radio burst.’ Parkes’ unique view of the southern sky, and cutting-edge instrumentation, means we have a great opportunity to contribute to the search for extra-terrestrial life,” said Douglas Bock, Director of CSIRO Astronomy and Space Science.

    Tags: Breakthrough Listen initiative, , Stephen Hawking's alien-hunting project is investigating strange signals from 234 stars   

    From Science Alert: “Stephen Hawking’s alien-hunting project is investigating strange signals from 234 stars”

    “Extraordinary claims require extraordinary evidence.”

    Astronomers have been analysing light signals from 2.5 million stars observed by the Sloan Digital Sky Survey, and have detected strange ‘strobe-like’ bursts coming from not one, but 234 stars.

    The pair went so far as to suggest that these light pulses “have exactly the shape of an Extra-Terrestrial Intelligence signal”, and now Stephen Hawking’s alien-hunting mission is on the case to confirm or disprove these claims.

    Let’s be clear right off the bat – the claim by astronomers Ermanno Borra and Eric Trottier from Laval University in Canada that 234 extra-terrestrial civilisations might be beaming a coordinated light signal towards Earth based on anomalies in the data is extremely premature.

    It’s also pretty irresponsible to be throwing the possibility of “Aliens!” around, given the fact that the paper has yet to be formally peer-reviewed, and replication of the results has not been attempted by an independent research team.

    It’s also worth noting that researchers from the Breakthrough Listen project – funded by Stephen Hawking and Russian billionaire Yuri Milner, and run by the SETI (Search for Extraterrestrial Intelligence) Research Centre at the University of California Berkeley – say aliens are about the last thing they expect to find when they investigate these claims.

    But when the Universe – or let’s be honest, human error – serves up something intriguing, it’s almost always worth a second look.

    “The one in 10,000 objects with unusual spectra seen by Borra and Trottier are certainly worthy of additional study,” the SETI Research Centre announced in a statement last week.

    “However, extraordinary claims require extraordinary evidence. It is too early to unequivocally attribute these purported signals to the activities of extraterrestrial civilisations.”

    So let’s run through what Borra and Trottier have actually found.

    Things start off a little wobbly, because as Shannon Hall explains for New Scientist, Borra had hypothesised back in 2012 that if an extraterrestrial civilisation wanted to contact us, it would make sense to beam laser pulses at us that look unnatural enough to warrant investigation.

    He said the kind of energy required to blast such a signal towards Earth from elsewhere in the galaxy “is not crazy”, so he teamed up with Trottier to pore over the 2.5 million stars recorded by the Sloan Digital Sky Survey to see if any of them have produced such a signal.

    And there’s our first warning signal – a good scientist knows not to approach data with a preferred result or preconceived notion in mind, because that can introduce bias, and the scientist could subconsciously (or otherwise) ignore information that goes against that.

    The pair reports that they detected the exact type of signal they had been looking for in some 234 stars.

    As Hall explains for New Scientist, if you take the aliens out of it, what they found was that the overwhelming majority of the 2.5 million stars are in the same spectral class as our Sun, but 234 of them are beaming pulses of the same periodicity – roughly 1.65 picoseconds – towards Earth.

    Could it be human or software error in data calibration or analysis? Absolutely, and the pair’s conclusions have – not surprisingly – been met with a whole lot of criticism in the scientific community.

    “There is perhaps no bolder claim that one could make in observational astrophysics than the discovery of intelligent life beyond the Earth,” director of the SETI Research Centre at Berkeley, Andrew Siemion, told Hall.

    “It’s an incredibly profound subject – and of course that’s why many of us devote our lives to the field and put so much energy into trying to answer these questions. But you can’t make such definitive statements about detections unless you’ve exhausted every possible means of follow-up.”

    That’s why the SETI Research Centre and the Breakthrough Listen project have decided to get involved – they want to know what’s really going on here.

    They explain that we already have internationally agreed-upon protocols if you want to find evidence of advanced life beyond Earth, which include independent verification using two or more telescopes, and “careful work” to determine false positive rates and rule out all other explanations.

    They’ve also established a 0 to 10 scale for quantifying detections of phenomena that may indicate the existence of advanced life beyond the Earth called the Rio Scale.

    They say the Borra-Trottier result is currently a 0 or 1 (“None/Insignificant”) on this scale, but they’re still determined to get to the bottom of things.

    “The Berkeley SETI Research Centre team has added several stars from the Borra and Trottier sample to the Breakthrough Listen observing queue on the 2.4-metre Automated Planet Finder (APF) optical telescope,” they announced last week.

    “The capabilities of the APF spectrograph are well matched to those of the original detection, and these independent follow-up observations will enable us to verify or refute the reported detections.”

    We’ll have to wait and see what they find, but let’s all be glad that if someone wants to throw claims of aliens around, they’d better be ready to answer to the SETI researchers first.

    From INVERSE: “Alien-Hunting 19 Years After ‘Contact’ “ 

    INVERSE

    INVERSE

    July 12, 2016
    Sarah Sloat

    Jodie Foster’s Eleanor Arroway and her mission would be less of a joke today.

    One of the most realistic parts of Contact is the blatant sexism that the brilliant young astronomer Eleanor Arroway encounters throughout the 1997 extraterrestrial-hunting film. The rumored inspiration for Arroway — Jill Tarter — said in 1999 that author Carl Sagan, who wrote the novel the movie was based off of, “included many of the ‘character-building’ experiences that are common to women scientists studying and working in a male-dominated profession, so Ellie seems very familiar to me.”

    SETI Jill Tarter
    Jill Tarter

    Carl Sagan
    Carl Sagan

    “Character-building” in this scenario is being a prominent SETI (Search for Extraterrestrial Intelligence) astronomer who has to deal with backward dudes who think your scientific expertise is laughable science fiction and won’t take you seriously because you’re a woman. Great.

    SETI Institute

    But for a movie that ends up with our protagonist on an intergalactic pseudo-beach chatting with an alien posing as her father, you may be surprised to know that what Contact nails doesn’t stop there. Contact’s realism is a reflection of the fact that Sagan knew what he was talking about. Until her breakthrough, Arroway lives a convincing life as a scientist — working out of the same observatories as real SETI researchers, fighting for funding, and hunting for alien life by listening for radio signals between 1,200 and 3,000 MHz from systematically selected stars.

    But what makes Arroway’s discovery of alien-transmitted communication from the star Vega awesome material for a Hollywood blockbuster is that it’s sold as a fantasy. Sagan knew the real science going on behind the fiction he created, but people who bought movie tickets didn’t. People in 1997 didn’t believe in SETI initiatives any more than the antagonists Arroway encountered.

    If Contact was to get a remake today (but seriously, no) it wouldn’t be able to instill the same sense of bewildered wonder. And that is a very good thing, namely because the work that Arroway portrays in the film is finally getting its due as a respectable field of science. Contact has proven to be prescient in 2016 (save for the actual we’ve-gotten-a-message-from-aliens part).

    Take billionaire Yuri Milner: In Contact Arroway’s work (and eventual voyage to Vega) is saved by the financial intervention of Dr. Hadden Suit, whose wealth seemingly has no bounds. Suit works from the shadows, moving the pieces in Arroway’s life, without the public knowing of the alien-hunting science going on behind closed doors. Comparatively, Milner is a real life financier who has made his intentions to help find evidence of extra-terrestrials extremely public.

    In 2015, Milner announced his Breakthrough Listen initiative in collaboration with the SETI program at the University of California, Berkeley — a $100 million project that uses telescopes to listen for extraterrestrial radio signals and search for laser signals.

    In January, he announced another $100 million dollar project with Breakthrough Starshot, an enterprise that plans to send laser-powered lightsails to the star system Alpha Centauri with the eventual goal of encountering life in deep space. That line, in any other year, would seem straight-up ridiculous.

    But things are a bit different in 2016. Arroway probably would not need to patiently break down how radio signals work to suits in the U.S. government when they begin to investigate her work; they’d probably already know what’s going on. Just look at the development of the FAST telescope being built in China, which Zheng Xiaonian of the Chinese Academy of Sciences says will have “the potential to search for more strange objects to better understand the origin of the universe and boost the global hunt for extraterrestrial life.”

    But mainly, a scientist of Arroway’s caliber wouldn’t have to take the same sort of inane criticism. SETI researchers are increasingly aware that they are no longer fringe weirdos. SETI communications director Seth Shostak told Inverse in January that, “I think there may be truth to SETI being taken more seriously by the public and it may be a consequence of the discovery of exoplanets filtering down to the public.”

    And while funding for exploratory science continues to be a struggle, SETI has been able to continue — and even increase — its programs. While it continues to monitor radio waves, sometimes with help of public laptops, SETI is also able to use optical instruments to look for lasers and light patterns that could signify the presence of aliens.

    In fact, on Thursday, SETI’s Institute Director of Research Nathalie Cabrol published a proposal arguing for further developing alien-hunting techniques, specifically through the establishment of Virtual Institute with “new detection strategies.”

    “To find E.T., we must open our minds beyond a deeply-rooted, Earth-centric perspective, expand our research methods, and deploy new tools,” said Cabrol in a press statement. “Never before has so much data been available in so many scientific disciplines to help us grasp the role of probabilistic events in the development of extraterrestrial intelligence. These data tell us that each world is a unique planetary experiment.”

    Cabrol’s words are comparable to that of Arroway’s, who praises the “acquisition of technology” as the catalyst for finally making contact probable. The good news for us: Cabrol is real, and one day, contact with aliens might be too.
