    SETI@home is shutting down. In an announcement posted yesterday, the project stated that they will no longer send data to SETI@home clients starting on March 31st, 2020 as they have reached a "point of diminishing returns" and have analyzed all the data that they need.
  • Astronomers want public funds for intelligent life search

    The UK's Astronomer Royal, Professor Lord Rees, is the chair of the organisation's international advisory group. He told the BBC that, given that the multi-billion pound Large Hadron Collider had not yet achieved its aim of finding sub-atomic particles beyond the current theory of physics, governments should consider modest funding of a few million pounds for Seti. "I'd feel far more confident arguing the case for Seti than for a particle accelerator," he said. "Seti searches are surely worthwhile, despite the heavy odds against success, because the stakes are so high". Nasa once funded the search for extra-terrestrial intelligence to...

    Hold on to your hats, skeptics. The study of alien existence is about to become a real scientific field. Pennsylvania State University is gearing up to make the search for extraterrestrial intelligence (SETI) an established field of scientific study. This means that a degree in Alien Research, no matter how outlandish it might sound, is soon going to be a real thing. According to a report, the university is planning on doing this by offering courses on the search for intelligent extraterrestrial life in its course catalog. It will also conduct actual research into the subject through it’s newly-established Penn...

    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.
  • Search for aliens poses game theory dilemma (old but interesting piece)

    New Scientist ^ | December 12, 2012 | Jacob Aaron
    SENDING messages into deep space could be the best way for Earthlings to find extraterrestrial intelligence, but it carries a grave risk: alerting hostile aliens to our presence. Game theory may provide a way to navigate this dilemma. So far the search for extraterrestrial intelligence (SETI) has mostly been restricted to listening for signs of technology elsewhere. Only a few attempts have been made to broadcast messages towards distant stars. Many scientists are against such “active” SETI for fear of revealing our presence. If all aliens feel the same way then no one will be broadcasting, and the chance of...

    A MYSTERIOUS object hurtling towards our Solar System may be an alien spacecraft. That's the shock claim made by one space scientist, who has exclusively revealed to The Sun that our incoming visitor could be piloted by hyper-intelligent beings. Last week, scientists in Germany announced they had spotted a distant object heading in our direction. Dubbed "C/2019 Q4", the high-speed body appears to be on a path originating from another star system that will see it fire past Mars in October. Despite numerous attempts to study C/2019, scientists remain clueless as to what it is. Many speculate the distant mass...

    While the truth might be out there, technological aliens don't seem to be — at least not yet. New results from the most comprehensive Search for Extraterrestrial Intelligence (SETI) program ever undertaken — which surveyed 1,327 nearby stars for signals from intelligent beings — have turned up empty. "There's certainly nothing out there glaringly obvious," ... lead author of a paper about the results, which were published in The Astrophysical Journal, told Live Science. "There's no amazingly advanced civilizations trying to contact us with incredibly powerful transmitters." While the team didn't find anything this time around, Price said that there...

    Astronomers have discovered that the planet Uranus has a blue ring - only the second found in the Solar System. Like the blue ring of Saturn, it probably owes its existence to an accompanying small moon. Scientists suspect subtle forces acting on dust in the rings allow smaller particles to persist while larger ones are recaptured by the moon. Smaller particles reflect blue light, giving the ring its distinctive colour, the US team reports in Science. All other rings - those around Jupiter, Saturn, Uranus and Neptune - are made up of both large and small particles, making the...

    A Neutrino Beam Beaconby Paul Gilsteron May 17, 2019 If you want to look for possible artifacts of advanced civilizations, as do those practicing what is now being called Dysonian SETI, then it pays to listen to the father of the field. My friend Al Jackson has done so and offers a Dyson quote to lead off his new paper: “So the first rule of my game is: think of the biggest possible artificial activities with limits set only by the laws of physics and look for those.” Dyson wrote that in a 1966 paper that repays study today (citation...

    For the precocious hunter of off-Earth life, the Drake equation is the ever-ready, go-to toolkit for estimating just how (not) lonely humans are in the Milky Way galaxy. The equation was developed by astronomer Frank Drake in 1961 in a slight hurry so that attendees of an upcoming conference would have something to confer about, and it breaks down the daunting question "Are we alone?" into more manageable, bite-size chunks. The equation starts with some straightforward concepts, such as the rate of star formation and the fraction of stars hosting planets. But it quickly moves into tricky terrain, asking for...

    Following its discovery in October 2017, ‘Oumuamua was the subject of popular speculation about a possible non-natural origin. Its highly elongated shape and the fact that no coma was observed strengthened this hypothesis for some, as these are uncharacteristic of asteroids and comets.A recent paper by Harvard Smithsonian Center for Astrophysics researchers Dr. Shmuel Bialy and Professor Abraham Loeb has also suggested the possibility that ‘Oumuamua is a deliberate construction.The scientists argued that the slight, unexpected acceleration observed for this object could be caused by pressure from sunlight as ‘Oumumua swung around the Sun. Their hypothesis is that the object...

    “A prior indigenous technological species might have arisen on ancient Earth or another body, such as a pre-greenhouse Venus or a wet Mars,” he wrote. ... Earth’s plate tectonics would effectively have “erased” the traces of a civilization that lived billions of years ago. Venus is in the grip of a severe greenhouse effect and also undergoes similar “resurfacing” that would scour it clean of artifacts. This leaves just a handful of places where archaeologists might find traces of a lost extraterrestrial civilization. “Remaining indigenous technosignatures might be expected to be extremely old, limiting the places they might still be...
  • Discovery of peculiar periodic spectral modulations in a small fraction of solar type stars

    Cornell University Library ^ | 10/10/2016 | E.F. Borra
    A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because they are present in only a very small fraction of stars within a narrow spectral range and because signal to noise ratio considerations predict that the signal should mostly be detected in the brightest objects, while this is not the case. We consider several possibilities, such as...

    Are the Laws of the Universe Fine-Tuned for Life? By Korey Haynes | November 12, 2018 Humans have often looked at the night sky and wondered if there’s anyone else out there. But stare into that darkness long enough, and many wonder instead: how did we get here? What were the odds, in a universe so enormous and chaotic, that humans should have come to exist at all? Is life, let alone intelligent life, such a wildly improbable occurrence that we’re the only ones here? Or are we an inevitable consequence of the laws of physics?Life exists on Earth (assuming...

    As recently as two years ago, SETI began picking up a different kind of signal — one that scientists can’t explain but believe that it isn’t born out of an attempt to communicate: fast radio bursts (FRBs). These FRBs are massively powerful; so powerful, in fact, that the leading natural explanation scientists can come up with is that they’re from “highly magnetized neutron stars, blasted by gas streams near to a supermassive black hole.” The problem with that explanation is that the bursts aren’t all coming from one specific place, but they are all coming from one specific region of...

    The German government has “no plans or protocol” should first contact with aliens occur, according to a report by German daily Bild. The government considers such an event “extremely unlikely according to current scientific knowledge,” the Ministry of Economics said when responding to a question from Green MP Dieter Janecek. “Concrete cases that could have been the subject of bilateral or multilateral talks with other states are not known,” the ministry’s statement continued. While Germany might not have a plan for extraterrestrial visitors, the US is more prepared. Even before the establishment of a Space Force that US President Donald...

    Ever since the Renaissance, the sciences have dealt human beings a steady stream of humiliations. The Copernican revolution dismantled the idea that humanity stood at the center of the universe. A cascade of discoveries from the late-18th to the early-20th century showed that humanity was a lot less significant than some had imagined. The revelation of the geological timescale stacked millions and billions of years atop our little cultural narratives, crumbling all of human history to dust. The revelation that we enjoy an evolutionary kinship to fish, bugs, and filth eroded the in-God’s-image stuff. The disclosure of the size of...

    A new radio telescope in Canada is doing its job picking up mysterious signals from deep space known as "fast radio bursts" (FRBs). The Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia detected the first-ever FRB at frequencies below 700 MHz on July 25, a signal named FRB 180725A. As you might guess, FRBs are milliseconds-long bursts of radio emissions that come from some unknown source across the universe. They're one of the newer cosmic mysteries around, having been first detected only about a decade ago. Possible explanations include bursts from magnetars, exploding black holes, and yes, highly advanced...
