Aliens Lose in Switch to Digital TV By Seth ShostakSenior Astronomer, SETI Instituteposted: 18 June 200905:07 pm ET The United States is finally ditching analog television broadcasting, and the rest of the world is doing the same. Unless you've got a converter, the government has just morphed your trusty analog boob tube into an inert piece of furniture. Mind you, this is a good thing. Digital TV (DTV) offers better picture quality. For example, the ghost images caused by signal reflections off that high-rise office building down the block will be a thing of the past. In addition, you...

SETI Invites Alien Talk May 24, 2009 — They may not be saying much to us, but we can think about what to say to them – aliens, that is.  Space.com reported on the latest project from the SETI Institute: invite people all over the world to ponder, “What would you say to an extraterrestrial civilization?”     The SETI Institute is launching a new website, Earth Speaks, to gather people’s ideas about what we should say to an alien civilization should contact be made.  “By submitting text messages, pictures, and sounds from across the globe,” CEO Thomas Pierson explained,...

If you'd asked 20 years ago the question he's heard over and over -- whether humanity will discover extraterrestrial intelligence in his lifetime -- Frank Drake would have shrugged and said, "sure." Today, the renowned astronomer, who turns 79 next month, admits the chances are slimming. "It's going to be a close call," he said. But even if Drake, professor emeritus of astronomy and astrophysics at the University of California at Santa Cruz, doesn't see the day we learn we're not alone, he knows it's coming. To him, it's a mathematical inevitability. He should know. He wrote the formula. And...

« A symposium called Crossroads: The Future of Human Life in the Universe seems timely about now (the site has been down all morning but should be up soon). With the Kepler mission undergoing calibration and CoRoT actively searching for small extrasolar worlds, we’re probably within a few dozen months of the detection of an Earth-like world around another star (and maybe, by other methods, much closer). This is sometimes referred to as the ‘Holy Grail’ of planetary sciences, but as soon as we accomplish it, a new ‘Grail’ emerges: The discovery of life on these worlds. And then...

IT’S a birthright proffered by science and prophesied by “Star Trek,” “Battlestar Galactica” and a thousand other space operas: We’re destined to go to the stars. Our descendants will spread beyond this nondescript solar system and seek adventure and bumpy-headed pals in the stellar realms. Well, cool your warp jets, Mr. Scott, because we’re not about to breach the final frontier. Piling into a starship and barreling into deep space may long remain —like perfect children or effort-free bathroom cleaners —a pipe dream. . . . [A] trip to Proxima Centauri, the nearest star beyond the Sun and 100 million...

The real geeks among us long for synthohol. Only Class A nerds know, or admit to knowing, what it is, too. But I have to tell you, your potential partner’s drinking it won’t make you any better looking. Better to stick with the real thing. I’d surely like to see cheap, readily available fusion power. With unlimited energy comes unlimited possibility. Medical advances never really grabbed my interest. Probably—and luckily—because I don’t have any sicknesses. Would be good to see genetics progress to the point where we can reliably clone humans so that we don’t deprive the world of another...

The Search for Extra-Terrestrial Intelligence (SETI) experiment ended up being far more successful as a marketing gimmick than as a science project. The intrepid researchers never found the little green men. Perhaps that's because they never aimed their high-dollar radio telescopes at The Church of England. The Right Rev Richard Chartres made the following comments that suggest his familiarity with how affairs are conducted on the third planet out from Sol is nodding at best. He addressed reporters covering the Church of England's General Synod on the financial crisis."Sometimes, people seem to be relieved to get off the treadmill and...

Frank Drake is being honored on Space.com by the SETI Institute as the “Father of SETI,” His reputation is providing an opportunity for a fund raiser. For a lot of money, you can spend time with a celebrity whose accomplishments are questionable...

'Aliens Cause Global Warming' From a lecture delivered by the late Michael Crichton at the California Institute of Technology on Jan. 17, 2003: Cast your minds back to 1960. John F. Kennedy is president, commercial jet airplanes are just appearing, the biggest university mainframes have 12K of memory. And in Green Bank, West Virginia at the new National Radio Astronomy Observatory, a young astrophysicist named Frank Drake runs a two-week project called Ozma, to search for extraterrestrial signals. A signal is received, to great excitement. It turns out to be false, but the excitement remains. In 1960, Drake organizes the...

For several decades scientists have been using telescopes to scan the heavens for unnatural-looking radio or optical transmissions coming from intelligent alien life. With this search for extraterrestrial intelligence (SETI) having so far failed to pick up a single signal, however, researchers in the US now believe it is worth extending the search beyond electromagnetic waves and start paying attention to neutrinos. John Learned of the University of Hawaii and colleagues have worked out that advanced alien civilizations could send messages within the Milky Way using neutrinos, and that these messages could be picked up using neutrino detectors currently under...

A widespread and popular impression of SETI is that it's a worldwide enterprise. Well, it's not, and there's something modestly puzzling in that. The idea of communicating between worlds is at least 150 years old. Victorian scientists Karl Friedrich Gauss and Joseph von Littrow are both reputed to have concocted schemes to establish rapport with Moon-men or Martians by signaling them with light. Gauss was a German, and von Littrow was Austrian. But within a century, the important ideas about getting in touch with aliens were coming from the western side of the Atlantic. The fundamental concepts for radio SETI...

BERKELEY, Calif. -- On Monday, KTVU reported scientists have received an odd signal from space and some readers may have interpreted this as a confirmed extra-terrestrial contact. Scientists did confirm there was an anomalous radio signal and reported it late last year. However, as SETI@home lead scientist Dan Werthimer now clarifies, "although this pulse is not well understood..." it may have a natural origin. SETI Institute Chief Scientist Seth Shostak says the highly energetic and brief signal at first excited some researchers, who at the time thought it may be a candidate ET signal. It was received not at Arecibo,...

The longest-running search for radio signals from alien civilizations is receiving 500 times more data from an upgraded telescope and better frequency coverage than project planners anticipated, meaning the SETI@home project is in dire need of more desktop computers to help crunch the data. New, more sensitive receivers on the world’s largest radio telescope in Arecibo, Puerto Rico, and better frequency coverage are generating 500 times more data for the project than before, project leaders said in a release. SETI@home software has been upgraded to deal with this new data as the search for extraterrestrial intelligence (SETI) enters a new...

ET too bored by Earth transmissions to respond 16:35 18 December 2007 NewScientist.com news service Tom Simonite Messages sent into space directed at extraterrestrials may have been too boring to earn a reply, say two astrophysicists trying to improve on their previous alien chat lines. Humans have so far sent four messages into space intended for alien listeners. But they have largely been made up of mathematically coded descriptions of some physics and chemistry, with some basic biology and descriptions of humans thrown in. Those topics will not prove gripping reading to other civilisations, says Canadian astrophysicist Yvan Dutil. If...

When Alexander Zaitsev presented his recent paper at the International Astronautical Congress in Hyderabad (India) recently, he spoke from the center of a widening controversy. The question is straightforward: Should we broadcast messages intentionally designed to be received by extraterrestrial civilizations, thereby notifying them of our existence? Zaitzev, chief scientist at the Russian Academy of Science’s Institute of Radio Engineering and Electronics, addressed the question by seeing a necessary relationship between SETI (the search for ETI) and METI (messaging to other civilizations). Indeed, the Russian scientist, working at the Evpatoria Deep Space Center in the Ukraine, has the experience to...

Today, in the remote northeast corner of California, technology innovator and Microsoft co-founder Paul Allen will hit the big red button. No, he won't be throwing heavy-duty machinery into an emergency shutdown, nor will he be sending ICBMs screaming from their silos (traditional functions for ruddy buttons). Instead, he'll be christening a new telescope that, in its significance, could eventually outpace the Nina, Pinta, and Santa Maria. The famous technologist will be inaugurating the initial 42 antennas of his namesake, the Allen Telescope Array (ATA) – the first major radio telescope designed from the pedestal up to efficiently (which is...

Nasa this week unveils a new emissary in the search for evidence of extraterrestrial life. The Phoenix Mars Lander, which launches next month, marks just the latest instalment in a quest that has exercised the imaginations of writers and scientists since long before the adventures of Jules Verne. In the 17th century Johannes Kepler, the architect of our modern understanding of the solar system, imagined a journey to a moon inhabited by serpent-like creatures called Prevlovans who endured the lunar night "bristling with ice and snow under the raging, icy winds". Regrettably, however, here is no reliable account of a...

NEW YORK: A panel of scientists convened by America's leading scientific advisory group says the hunt for extraterrestrial life should be greatly expanded to include what they call "weird life": organisms that lack DNA or other molecules found in life as we know it. "The committee's investigation makes clear that life is possible in forms different from those on Earth," the scientists conclude in their report. Starfish, sequoias, salamanders and the rest of Earth's residents may seem very diverse, but they are surprisingly similar on the molecular scale. All species that scientists have studied need liquid water to survive, for...

PALMDALE - The world's newest flying telescope will be in focus on Saturday, June 30, at NASA's Aerospace Exploration Gallery in the Palmdale Civic Center. Dr. Dana Backman will give presentations regarding NASA's Stratospheric Observatory for Infrared Astronom beginning at 9 a.m., then repeating at 10:30, noon and 1:30 p.m. Dr. Backman is with the SETI Institute and the Universities Space Research Association and manages SOFIA's education and public outreach program. An infrared astronomer, Backman received his doctoral degree in astrophysics from the University of Hawaii. While Backman was a post-doctoral student at NASA's Ames Research Center, he flew on...

OK, don't make a mistake: this isn't really a movie about space. The Astronaut Farmer is the quintessential American Story. That's right; it's the classic, archetypical, consummate, perfected American myth, served up in packaging so homespun, you'll wonder that the actors aren't dressed in quilts. When it comes to this movie's theme, you already know the drill, because during your childhood, Hollywood saut?ed your tender brain with the potboiler genre known as the Western. And what was the icon of the Western? A rugged individual, hard as tool steel on the outside, and soft as warm Jell-O within; a slouch-hatted...
