Aliens in no mood to response to SETI right now

The SETI (Search For Extraterrestrial Intelligence) telescope has produced its first scientific results, but unfortunately it’s still waiting for a response from the aliens.

The project, called the Allen Telescope Array (ATA) after benefactor and Microsoft co-founder Paul Allen, went live in 2007.

It was designed to scan for broadcasts from alien civilizations with more consistency and a wider field of view than any previous effort.

Run jointly by the SETI Institute and the University of California, Berkeley, from a site in northern California, the ATA is ultimately intended to comprise 350 dishes.

But, even with its current complement of 42, it has an impressively wide field of view. It uses relatively small, 6-metre dishes that together can take in five square degrees of sky at a time – a box as wide as 10 full moons.

“At any one moment, you look into a very large piece of the sky,” said Jill Tarter, director of the SETI Institute. “At 350 (telescopes), the ATA just blows any other survey telescope out of the water. Even at 42, it’s interesting,” she told New Scientist.

According to Joeri van Leeuwen, an ATA team member who presented the project’s first results at a conference in the Netherlands in June, “You can see entire galaxies within one shot.”

One question the ATA aims to answer is a mystery of missing gas.

Star-forming regions don’t seem to have enough molecular gas to keep up the star-formation rates we observe.

Some researchers think atomic hydrogen might make up the difference.

ATA team members have searched for it in four groups of galaxies so far, but have not yet found any new intergalactic gas, deepening the mystery.

“This paper was our first science paper, so we’ve answered some questions, but we’re finding new questions again. This paper really shows that our setup is working, we have all the algorithms working, and we could easily upgrade to a more powerful system still,” van Leeuwen said.

Such surveys do not distract from the search for aliens, which – if they exist and are attempting to communicate – may send out broadcasts at wavelengths not commonly emitted by astrophysical objects.

    Dudes, SETI is just a distraction to make the public realm believe that the established scientific community is "on top of it". Pffff…Contact has alrady been made, do some research around the Web. Read up at http://www.disclosureproject.org . I mean, if the thousands of credible UFO reports and hey, why not crop circles, aren't enough to convince you…well, just keep banking on SETI, but don't expect them to come clean on any eventual contact of theirs, the establishment has a huge veil on this topic and it isn't likely to make some life-altering announcements.

    The SETI project has a signal verification protocal that would ask for confirmation of any signal by astronomers all over the globe and these geeks are not all government controlled, part of the non disclosure conspiracy.
    I do believe in ufo's and in the conspiracy and also that ultimatly proof will come from astronomers. That the thousands of teloscopes taking daily pictures of the skys have not been able to confirm ufos is due to this protocol, among other reasons such as professional reputations. Frustrating the efforts of these star gazers is thhe interdimentional nature of ufos. telescopes dont look across dimentions.
