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...

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...

(Phys.org) —Scientists as eminent as Stephen Hawking and Carl Sagan have long believed that humans will one day colonise the universe. But how easy would it be, why would we want to, and why haven't we seen any evidence of other life forms making their own bids for universal domination? A new paper by Dr Stuart Armstrong and Dr Anders Sandberg from Oxford University's Future of Humanity Institute (FHI) attempts to answer these questions. To be published in the August/September edition of the journal Acta Astronautica, the paper takes as its starting point the Fermi paradox – the discrepancy between...

UFOs may be fodder for comedians and science fiction but there was no joking Monday when a group of pilots and officials demanded the US government reopen an investigation into unidentified flying objects. The 19 former pilots and government officials, who say they have seen UFOs themselves or been involved in probes of strange flying objects, told reporters their questions can no longer be dismissed more than 30 years after the US case was closed."We want the US government to stop perpetuating the myth that all UFOs can be explained away in down-to-earth, conventional terms," said Fife Symington, former governor...

The Starship Builders by Kim Burrafato In UFOs and the New Physics, we discussed some of the daunting problems in applying terrestrial rocket propulsion principles to any hypothetical models of UFO propulsion. A lot has happened since that article?s publication over two years ago. It seems we?re getting almost weekly reports of newly discovered extrasolar planetary systems. What was once highly speculative, is now commonplace. Obviously, our previous estimates of the number of stars with possible planetary systems will be revised dramatically upwards. Then there is the recent announcement from a distinguished British research team, that they also had...

On Monday, famed physicist Stephen Hawking and Russian tycoon Yuri Milner held a news conference in London to announce their new project: injecting $100 million and a whole lot of brain power into the search for intelligent extraterrestrial life, an endeavor they're calling Breakthrough Listen. "We believe that life arose spontaneously on Earth," Hawking said at Monday's news conference, "So in an infinite universe, there must be other occurrences of life." Geoffrey Marcy, a University of California, Berkeley, astronomer who found most of our first exoplanets, also spoke at the event as part of the group's brain trust....

A $100 Million Infusion for SETI Researchby Paul Gilster on July 20, 2015 SETI received a much needed boost this morning as Russian entrepreneur Yuri Milner, along with physicist Stephen Hawking and a panel including Frank Drake, Ann Druyan, Martin Rees and Geoff Marcy announced a $100 million pair of initiatives to reinvigorate the search. The first of these, Breakthrough Listen, dramatically upgrades existing search methods, while Breakthrough Message will fund an international competition to create the kind of messages we might one day send to other stars, although the intention is also to provoke the necessary discussion and debate...

Russian billionaire Yuri Milner announces most comprehensive hunt for alien life.You could say that the silence has been deafening. Since its beginnings more than half a century ago, the dedicated search for extraterrestrial intelligence (SETI) has failed to detect the presence of alien civilizations. But at London’s Royal Society today (20 July), Russian billionaire Yuri Milner announced a shot in the arm for SETI: a US$100-million decadal project to provide the most comprehensive hunt for alien communications so far. The initiative, called Breakthrough Listen, will see radio telescopes at Green Bank in West Virginia, the Parkes Observatory in Australia, and...

Is there anyone else out there in the universe? The endeavor to answer that eternal question got a serious shot in the arm this week thanks to Russian entrepreneur Yuri Milner. At the Royal Society in London, the billionaire announced the launch of Breakthrough Listen, a 10-year, $100 million initiative to search for signs of extraterrestrial life.
