The other parts of the project is an undirected search which is monitoring all of the space with a lower using the smaller antennas of NASA`s Deep Space Network.

This part of the project is searching the nearest 1000 likely stars with a high sensibility for signals in the frequency range 1000 to 3000 MHz. Puerto Rico and the French telescope in Nancy in France. The American-operated telescope in Arecibo. One part is a targeted search using the world's largest radio telescopes. Much of the money in this project is being spent on developing the special hardware needed to search many frequencies at once. The scale of the searches has been increased dramatically since 1992, when the US Congress voted NASA $10 million per year for ten years to conduct a thorough search for extra-terrestrial life. Until now there have not been any detections from the few hundred stars which have been searched. So far there have been a number of searches by various groups around the world, including Australian searches using the radio telescope at Parkes, New South Wales. and so all searches to date have concentrated on looking for radio waves in this frequency range. for a given amount of transmitted power: radio waves in the frequency range 1000 to 3000 MHz travel the greatest distance. or else are severely attenuated while traversing the vast distances across the galaxy. It is even possible that the older civilization may pass on the benefits of their experience in dealing with threats to survival such as nuclear war and global pollution, and other threats that we haven't yet discovered.Р”Р„n alien civilization could choose many different ways of sending information across the galaxy, but many of these either require too much energy. The mere existence of such a civilization will tell of that long-term survival is possible, and gives us some cause for optimism.

Thus anyР’В other civilization that we hear from is likely to be far older on average than ourselves.

Will we last another two thousand years or will we wipe ourselves out? Since the lifetime of a planet like ours is several billion years, we can expect that if other civilizations do survive in our galaxy, their ages will range from zero to several billion years. For example, we have had civilization on Earth for perhaps only a few thousand years, and the threats of nuclear war and pollution over the last few decades have told us that our survival may be tenuous. However, there are other reasons for being interested in whether life exists elsewhere. In this sense, SETI is another cog in the machinery of pure science which is continually pushing out the horizon of our knowledge. The simple detection of a radio signal will be sufficient to answer this most basic of all questions. We want to know whether life evolves naturally if given the right conditions, or whether there is something very special about the Earth to have fostered the variety of life forms that we see around us on the planet. We want to know whether we are alone in the Universe. The primary reason for the search is basic curiosity - the same curiosity about the natural world that drives all pure science.
