    The truth is out there — or at least that’s what researchers at NASA and the Search for Extraterrestrial Intelligence (SETI) Institute are hoping. While much of the SETI Institute’s research involves scanning space for light and radio signals as indicators of extraterrestrial life, it’s also looking for bigger objects — and specifically alien megastructures. “[It’s] essentially any artificial structure built by an intelligent civilization perhaps for energy harvesting purposes,” Ann Marie Cody, a researcher scientist at NASA Ames and the SETI Institute, told Vice in a fascinating new interview. The method that Cody and her colleagues employ to try...

    Last December news leaked that the Breakthrough Listen project, part of the Search for Extraterrestrial Intelligence (SETI), had picked up an unexplained signal from the direction of Proxima Centauri. Although everyone involved stressed how unlikely it was that our first evidence for alien intelligence would come from the nearest star to our Sun, some dared to hope. Further research, however, has made Earth-based interference a near-certain explanation. There are many reasons to study Proxima Centauri besides the possibility of technological radio emissions. Australia’s giant Murriyang radio telescope was pointed towards the star primarily to study stellar flares, but in the...

    Seventy years ago, Italian-American nuclear physicist Enrico Fermi asked his colleagues a question during a lunchtime conversation. If life is common in our Universe, why can’t we see any evidence of its activity out there (aka. “where is everybody?”) Seventy years later, this question has launched just as many proposed resolutions as to how extraterrestrial intelligence (ETIs) could be common, yet go unnoticed by our instruments. Some possibilities that have been considered are that humanity might be alone in the Universe, early to the party, or is not in a position to notice any yet. But in a recent study,...

    ‘Hycean’ Worlds: A New Candidate for Biosignatures?by Paul Gilsteron August 27, 2021We’ve just seen the coinage of a new word that denotes an entirely novel category of planets. Out of research at the University of Cambridge comes a paper on a subset of habitable worlds the scientists have dubbed ‘Hycean’ planets. These are hot, ocean-covered planets with habitable surface conditions under atmospheres rich in hydrogen. The authors believe they are more common than Earth-class worlds (although much depends upon their composition), and should offer considerable advantages when it comes to the detection of biosignatures.Hycean worlds give us another habitable zone,...

    The principle underlying dynamical ptychography One of the topics investigated in recent physics studies is strong-field quantum electrodynamics (SF-QED). So far, this area has rarely been explored before, mainly because the experimental observation of SF-QED processes would require extremely high light intensities (>1025W/cm2), over three orders of magnitude higher than those attained using the most intense PetaWatt (PW)-class lasers available today.A SF-QED process that has proved to be particularly difficult to observe is the Schwinger process. This is a process that occurs close to the so-called Schwinger limit (1029/cm2), which is associated with the optical breakdown of the quantum...

    In 1960, the first survey dedicated to the Search for Extraterrestrial Intelligence (SETI) was mounted at the Green Bank Observatory in West Virginia. This was Project Ozma, which was the brainchild of famed astronomer and SETI pioneer Frank Drake (for whom the Drake Equation is named). Since then, the collective efforts to find evidence of life beyond Earth have coalesced to create a new field of study known as astrobiology. The search for extraterrestrial life has been the subject of renewed interest thanks to the thousands of exoplanets that have been discovered in recent years. Unfortunately, our efforts are still...

    Aerospace entrepreneur Robert Bigelow made a cryptic announcement in September 2008 in a radio interview with George Knapp. Bigelow revealed that he had just created BAASS, a subsidiary of Bigelow Aerospace, and that BAASS had entered into a partnership with an unnamed entity to study the UFO mystery and related phenomena. The public didn’t know it at the time, but one week earlier, Bigelow had signed a contract with the Defense Intelligence Agency to carry out an investigation under the umbrella of AAWSAP, the Advanced Aerospace Weapons Systems Application Program. The impetus for the program had occurred a year earlier...

    This aerial view shows the damage to the Arecibo Observatory after its 900-ton equipment platform broke loose, swung into a nearby rock face, and smashed onto the radio dish below. ==================================================================== The Arecibo Observatory’s suspended equipment platform fell hundreds of feet and crashed through the giant radio dish. The Arecibo Observatory’s suspended equipment platform collapsed just before 8 a.m. local time on December 1, falling more than 450 feet and crashing through the telescope’s massive radio dish—a catastrophic ending that scientists and engineers feared was imminent after multiple cables supporting the platform unexpectedly broke in recent months. No one was...

    The world-famous Arecibo Observatory in Puerto Rico, known for helping scientists peer into deep space and listen for distant radio waves, is set to be decommissioned and demolished after engineers concluded that the facility’s structure is at risk of a collapse. While teams will try to salvage some parts of the observatory, the decommission will bring an end to the popular 57-year-old telescope, which has been featured in numerous films and television shows. The decision comes after two major cables failed at the facility within the last few months, causing significant damage to the observatory. The National Science Foundation (NSF),...

    The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of 4096 antennas planted in the red soil of Western Australia that detects radio signals from space. "They are little spider-like antennas that sit on the ground," explains Chenoa Tremblay, co-author on the study and astrophysicist with CSIRO, an Australian government scientific research organization. Tremblay and co-author Stephen Tingay, from the International Centre for Radio Astronomy Research, used the MWA to listen out for "technosignatures," or evidence of alien technology, in a...

    On Monday (Aug. 10), an auxiliary cable supporting a platform that is suspended above the 1,000-foot-wide (300 meters) radio dish broke and crashed into the telescope's reflector panels, creating a gash in the dish measuring about 100 feet (30 m) long. In a news conference with reporters Friday (Aug. 14), Arecibo director Francisco Cordova said that 250 of the observatory's primary reflector dish panels were damaged, along with several support cables underneath the dish. But observatory officials have not yet fully assessed the extent of the damage or determined the cost of the repairs needed to get the 56-year-old radio...

    At Arecibo, scientists conduct all sorts of work, from atmospheric and planetary science through to radio and radar astronomy and even searches for extraterrestrial intelligence, also known as SETI. The purpose of these observations are to determine the ways in which red dwarf stars, like Barnard’s Star, affect the habitability of their planets. Méndez was also planning to embark on a SETI project to detect extraterrestrial technosignatures (i.e. evidence of alien technology), which would have leveraged both past and future observations at Arecibo. All this now appears to be on hold. Méndez’s observations aren’t time critical, but others might be,...

    In an article over at Space.com, Leonard David describes a new development in the efforts by humans to contact extraterrestrial life elsewhere in the galaxy. While the SETI program (Search for Extraterrestrial Intelligence) has been in operation for decades, the results thus far have been mostly disappointing. There was a brief flurry of excitement in 1977 when “the WOW signal” was received, but in later years even that one has been called into question. Now, however, there’s a new player in the game. China has constructed the largest single-dish radio telescope in the world and they are reportedly gearing up...

    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.

    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...
