SETI’s latest search for aliens has come to a disappointing conclusion. Part of the problem is our own technology. We just aren’t that advanced. SETI is only capable of searching for Type II civilizations, who utilize and channel an energy source equivalent to the sun. So, yeah…there probably aren’t too many of those.

The other problem is even more challenging to overcome. Searching for aliens has always struck me as a long-shot. Sure, the galaxy is vast but so is time. And the odds of our civilization overlapping with a similar one (actually a much more advanced one) on a distant planet have got to be miniscule. Here’s more on the latest SETI search from Ian O’Neill at Discovery News:

In an effort to search for intelligent extraterrestrials, SETI astronomers have completed their first “directed” search. Unfortunately, it turned up no evidence of transmitting aliens. But that’s hardly surprising.

By focusing the Green Bank radio telescope, located in West Virginia, on stars hosting (candidate) exoplanets, it is hoped that one of those star systems may also play host to a sufficiently evolved alien race capable of transmitting radio signals into space. But in a study headed by ex-SETI chief Jill Tarter, the conclusion of this first attempt is blunt: “No signals of extraterrestrial origin were found.”
