A Career Waiting for E.T. to Phone
By DENNIS OVERBYE Jill Tarter once complained to me that she had no poetry in her soul. It was 1990, and NASA was getting ready to undertake a survey of the 1,000 nearest stars, looking for radio signals from aliens. Dr. Tarter, then 46 and a researcher at NASA’s Ames Research Center in Mountain View, […]
First VLBI SETI Search Finds No Radio Transmissions
May 31, 2012
… From Gliese 581 Astronomers have completed the first search for extraterrestrial intelligence on nearby exoplanets using very long baseline interferometry A telescope’s angular resolution is its ability to distinguish small details of a distant object. The Hubble Space telescope, for example, has an angular resolution of about 100 milliarcseconds. That’s good but by no […]
How would the public react if Seti found evidence of alien life?
May 21, 2012
‘In a sense, we’ve run that experiment,’ says Seth Shostak, chief alien hunter at the Search for Extraterrestrial Intelligence Read more: www.guardian.co.uk
Time to give SETI a chance
February 12, 2012
by Jill Tarter - newscientist Earth 2.0 is in our sights. Checking it for signs of life will be the next big issue THE thousands of probable worlds discovered in orbit around other stars are making our corner of the universe appear a lot friendlier to life these days. The Kepler space telescope, which has its […]
The Fermi Paradox, Self-Replicating Probes …
November 29, 2011
… and the Interstellar Transportation Bandwidth Keith B. Wiley It has been widely acknowledged that self-replicating space-probes (SRPs) could explore the galaxy very quickly relative to the age of the galaxy. An obvious implication is that SRPs produced by extraterrestrial civilizations should have arrived in our solar system millions of years ago, and furthermore, that […]
Detection Technique for Artificially-Illuminated Objects ….
November 1, 2011
….in the Outer Solar System and Beyond Abraham Loeb and Edwin L. Turner Existing optical telescopes and surveys can detect artificially-illuminated objects comparable in total brightness to a major terrestrial city at the outskirts of the Solar System. Orbital parameters of Kuiper belt objects (KBOs) are routinely measured to exquisite precisions of <10<sup>-3</sup>. Here we […]
How SETI@Home Screens ET Candidates
September 13, 2011
SETI@Home volunteers have found 4.2 billion signals of interest since the project began in 1999. What happens to them? SETI@Home is a distributed computing initiative that analyses radio signals for signs of extra terrestrial intelligence. It relies on volunteers who use their own computers to download and crunch data from the Arecibo Radio telescope in […]
Life in the Universe by Stephen Hawking
August 28, 2011
In this talk, I would like to speculate a little, on the development of life in the universe, and in particular, the development of intelligent life. I shall take this to include the human race, even though much of its behaviour through out history, has been pretty stupid, and not calculated to aid the survival […]
Status of the UC-Berkeley SETI Efforts
August 17, 2011
We summarize radio and optical SETI programs based at the University of California, Berkeley. The SEVENDIP optical pulse search looks for ns time scale pulses at visible wavelengths using an automated 30 inch telescope. The ongoing SERENDIP V.v sky survey searches for radio signals at the 300 meter Arecibo Observatory. The currently installed configuration supports […]
Search for ET: The high-profile supporters
August 11, 2011
The resumption of operations at California’s Search for Extraterrestrial Intelligence Institute (SETI) was made possible by donations from celebrity supporters including Jodie Foster. Following an appeal on the website of the Allen Telescope Array project, named after its first financial backer, Microsoft co-founder Paul Allen, donations from more than 2,200 supporters – known as SETIStars […]
