News -01-25-06 Earth-Like Planet Discovered (SETI.org) "So here’s the strategy. The aliens could decide to use a highly directional antenna (maybe an array) to beam a short, intense pulse to a long list of bio-worlds. They repeat this serial signaling project every 20 minutes, for example. If each pulse is one-thousandth of a second long, their list will comprise about a million targets, enough to provide a decent chance for including at least one star system sporting some nerdy creatures able to build big radio telescopes. That’s the 'hailing' signal; the one whose only purpose is to get someone’s attention. It’s the first tier of the strategy." "The second step is even simpler. If we, or any other society, find that hailing signal (and it could be easily verified, as it repeats every 20 minutes in our example), you can bet that we’d pull out all the stops to examine the patch of sky from which it came, looking for additional signals." "If any extraterrestrials are signaling with such a two-tiered scheme, we need to modify our traditional SETI observations to find them." 01-06 -06-18-07 Correct Star, Wrong Planet (MSNBC News) "Scientists earlier this year announced they had found a small, rocky planet located just far enough from its star to sustain liquid water on its surface, and thus possibly support life." "Turns out the scientists might have picked the right star for hosting a habitable world, but got the planet wrong. The world known as Gliese 581c is probably too hot to support liquid water or life, new computer models suggest, but conditions on its neighbor, Gliese 581d, might be just right." 06-07 Papers NASA Looks for Extraterrestrial Life (CNN News) "As NASA prepares to hunt for Earth-like planets in our corner of the Milky Way galaxy, there's new buzz that 'Star Trek's' vision of a universe full of life may not be that far-fetched." "In a paper published recently in the International Journal of Astrobiology, the researchers concluded that based on what they saw, at least 361 intelligent civilizations have emerged in the Milky Way since its creation, and as many as 38,000 may have formed." 02-09 Search for Extraterrestrial Intelligence Life (SETI.org)
