In the scientific community, there is still a great deal of energy devoted to “listening” for evidence or hints of intelligent, extraterrestrial civilizations out among the stars. Most of you are probably familiar with the Search for Extraterrestrial Intelligence (SETI) and their decades of work in this field. They’re still at it and, in fact, are upping their game with a new generation of laser sensors. These projects drew fresh attention after the discovery of Tabby’s Star and the frantic speculation over whether or not some ancient civilization had built a Dyson Sphere around their own sun. This has led...

Interstellar Trade Is Possible In this post, we will detail a method for developing interstellar trade using near-future technologies and commercially realistic requirements. We will then look at the various outcomes, challenges and development models that will follow the first interstellar operation. There is now a Summary at the end of the post. A tough taskTravel between stars is hard. The distances are measured in trillions of kilometers and the space between destinations is not really empty. Attempting the crossing at interplanetary speeds is ludicrously slow; the only way is to reach velocities measured in percentages of the speed of...

Roughly half a century ago, Cornell astronomer Frank Drake conducted Project Ozma, the first systematic SETI survey at the National Radio Astronomy Observatory in Green Bank, West Virginia. Since that time, scientists have conducted multiple surveys in the hopes of find indications of “technosignatures” – i.e. evidence of technologically-advanced life (such as radio communications). ...But according to a new study, such a message could also pose a serious risk to humanity. Drawing on multiple possibilities that have been explored in detail, they consider how humanity could shield itself from malicious spam and viruses. The study, titled “Interstellar communication. IX. Message...

Scientists searching space for intelligent life already have a difficult job, but some are now saying their task is being made even tougher because of digital currencies like Bitcoin. “We’d like to use the latest GPUs (graphics processing units)… and we can’t get ’em,” Dr. Dan Werthimer told the BBC. The chief scientist of the Search for Extraterrestrial Intelligence, or SETI Project, says the surging demand for GPUs from cryptocurrency miners is leaving the computer chips in short supply. “This is a new problem, it’s only happened on orders we’ve been trying to make in the last couple of months,”...

Roughly half a century ago, Cornell astronomer Frank Drake conducted Project Ozma, the first systematic SETI survey at the National Radio Astronomy Observatory in Green Bank, West Virginia. Since that time, scientists have conducted multiple surveys in the hopes of find indications of “technosignatures” – i.e. evidence of technologically-advanced life (such as radio communications). To put it plainly, if humanity were to receive a message from an extra-terrestrial civilization right now, it would be the single-greatest event in the history of civilization. But according to a new study, such a message could also pose a serious risk to humanity. Drawing...

A leading astronomer studying the origins of the space object known as Oumuamua has come out declaring it’s an alien probe with broken engines. Dr. Jason Wright claims that Oumuamua’s movement is that of a craft that has lost power to its engines. Right now, leading scientists are studying the odd “cigar-shaped” object which originated outside of our solar system. Teams lead by renowned physicist, Stephen Hawking, are attempting to discover whether or not Oumuamua is alien or natural. If a radio signal is detected later today, scientists will “proceed with caution.” Professor Avi Loeb, Professor of Astronomy at Harvard...

Etiology of Alien Derangement Syndrome August 2, 2017 | David F. Coppedge With no evidence for their invisible friends, believers in space aliens are losing their minds. Are they setting themselves up for mass deception? Another mystery signal from space has been solved, Phys.org announces. Bad news: It’s not aliens. This has become a common scenario: believers get excited about the possibility of a signal from their imaginary friends (6/15/17), only to find out there’s a natural explanation, and the alien-of-the-gaps explanation gets narrower. The case of the “Weird!” signal from dim star Ross 128 was admittedly a long shot,...

Sorry, everybody. We’re just not that special. In more than five decades of scanning the heavens, the search for extraterrestrial intelligence (SETI) has found no sign of alien life. Yet now two American astronomers, in the scientific equivalent of a back-of-the-envelope calculation, are estimating that over the course of its history the universe has seen at least half a trillion technologically advanced species. Remember, 420 billion intelligent civilizations is the “pessimistic” estimate. But sadly—or happily, depending on your view of aliens—it doesn’t make us any less alone.

The Breakthrough Listen project is managed by a team at the University of California, Berkeley, SETI Research Center and uses the Parkes Telescope in Australia, the Green Bank Telescope in West Virginia and the Automated Planet Finder optical telescope at Lick Observatory in California to collect radio signal data – a LOT of radio signal data. In just two years, the project has accumulated eight petabytes (8 million gigabytes) of data from observations of just 692 stars that have been designated as possible candidates for alien life – a total of 1709 stars have been selected for the project. Each...

An international team of scientists from the Search for Extraterrestrial Intelligence (SETI) is investigating mysterious signal spikes emitting from a 6.3-billion-year-old star in the constellation Hercules—95 light years away from Earth. The implications are extraordinary and point to the possibility of a civilization far more advanced than our own. The unusual signal was originally detected on May 15, 2015, by the Russian Academy of Science-operated RATAN-600 radio telescope in Zelenchukskaya, Russia, but was kept secret from the international community. Interstellar space reporter Paul Gilster broke the story after the researchers quietly circulated a paper announcing the detection of “a strong...

An Interesting SETI Candidate in Hercules by Paul Gilster on August 27, 2016 A candidate signal for SETI is a welcome sign that our efforts in that direction may one day pay off. An international team of researchers has announced the detection of “a strong signal in the direction of HD164595” in a document now being circulated through contact person Alexander Panov. The detection was made with the RATAN-600 radio telescope in Zelenchukskaya, in the Karachay–Cherkess Republic of Russia, not far from the border with Georgia in the Caucasus. The signal was received on May 15, 2015, 18:01:15.65 (sidereal time),...

Installation was completed on the world's largest radio telescope on Sunday morning as the last of 4,450 panels was fitted into the center of the big dish. ... In the first two or three years after its completion, the telescope will undergo further adjustment, and during that period Chinese scientists will use it for early-stage research. After that, it will be open to scientists worldwide, said Peng Bo, director of the NAO Radio Astronomy Technology Laboratory. Scientists can also carry out remote control and observation in other cities such as Beijing, more than 2,000 kilometers from the telescope site, said...

When it comes to detecting laser pulses aliens might shoot at Earth to attract our attention, scientists now find they can detect signals as faint as a single photon of light every few tiny fractions of a second. Astronomers have gazed at the skies for decades searching for signs of extraterrestrial intelligence. Lasers can in principle help transmit messages over extraordinary distances, but while scientists have monitored a large number of stars looking for alien laser signals — for instance, facilities at Harvard and Princeton scanned more than 10,000 sun-like stars for several years — no evidence for any have...

Sorry, E.T. lovers, but the results of a new study make it far less likely that KIC 8462852, popularly known as Tabby's star, is the home of industrious aliens who are gradually enclosing it in a vast shell called a Dyson sphere. Public interest in the star, which sits about 1,480 light-years away in the constellation Cygnus, began last fall when Yale astronomer Tabetha ("Tabby") Boyajian and colleagues posted a paper on an astronomy preprint server reporting that "planet hunters" - a citizen science group formed to search data from the Kepler space telescope for evidence of exoplanets - had...

China Spends Millions Searching for (Space) Aliens by Brian Thomas, M.S. * How much money should a nation spend on space-alien ventures? China is shelling out almost 200 million dollars on an enormous radio antenna built to listen for signs of far out intelligence.1 In the western hemisphere, the US invested millions of dollars in the Search for Extraterrestrial Intelligence Institute (SETI) project but turned up no evidence whatsoever.2 The ever-growing number of barren and gaseous exoplanets discovered continues to elevate Earth's uniqueness.3 Apparently, China would love to be the first nation to make "first contact." China recently made news...

Exoplanet Census Suggests Earth Is Special after All A new tally proposes that roughly 700 quintillion terrestrial exoplanets are likely to exist across the observable universe--most vastly different from Earth By Shannon Hall on February 19, 2016 Share on Facebook Share on Twitter Share on Reddit Email Print Share via Google+Stumble Upon NASA/ESA/ESO Advertisement More than 400 years ago Renaissance scientist Nicolaus Copernicus reduced us to near nothingness by showing that our planet is not the center of the solar system.

NASA's Spirit Mars Rover Found Mysterious Growths On Mars That Could Be The Biggest Discovery In Science Jennifer Deal February 5, 2016 Four billion years ago, Mars looked a lot like Earth does today. So it's not surprising that a team of scientists believe that they may have discovered the first signs of ancient alien life on the planet.(click to the site to see the video)

Scientists Debate Signatures of Alien Life Searching for signs of life on faraway planets, astrobiologists must decide which telltale biosignature gases to target. Photo illustration by Olena Shmahalo/Quanta Magazine February 2, 2016 Comments (5) Share this: facebooktwitterredditmail PDF Print Huddled in a coffee shop one drizzly Seattle morning six years ago, the astrobiologist Shawn Domagal-Goldman stared blankly at his laptop screen, paralyzed. He had been running a simulation of an evolving planet, when suddenly oxygen started accumulating in the virtual planet’s atmosphere. Up the concentration ticked, from 0 to 5 to 10 percent.“Is something wrong?” his wife asked.“Yeah.”The rise of...

Two big ideas often come up in discussions about the search for extraterrestrial intelligence, or SETI. One is the Drake Equation, which estimates the number of civilizations in our Galaxy whose signals we might be able to detect--potentially thousands, according to plausible estimates. The other is the so-called Fermi paradox, which claims that we should see intelligent aliens here if they exist anywhere, because they would inevitably colonize the Galaxy by star travel--and since we don't see any obvious signs of aliens here, searching for their signals is pointless. The Drake Equation is perfectly genuine: it was created by astronomer...

While Hawking fears that giving aliens our cosmic address could potentially bring death and ruin — much like what happened to many groups of Native Americans when Europeans invaded North America — Tarter thinks that aliens advanced enough to skip across star systems and reach Earth will be friendly, not aggressive.  
