I don't understand this part - "By setting distance as the criteria, the SETI team hopes to alleviate any bias that might otherwise result from focusing on systems similar to that of Earth. The team selected stars for study based only on how far they lie from the sun." - What's wrong with aiming toward systems we think might have planets capable of supporting life?

I still think the possibility of earth being in the path of two ET civilizations communicating with each other is real close to zero.

Gordon - SETI@Home does not have control of where the Arecebo telescope is pointing, it simply hasn't the cash to do so. All it does is to do a parallel collection from wherever the telescope is pointing.

That's what I thought, but I got the impression a new project was in the works, and it was going to zero in on stars that have no confirmed planets, which seems strange to me.

In a recent announcement SETI astronomers unveiled two new projects intending to find signals of extraterrestrial intelligence within our Universe.

First among its new projects is SETI’s Panchromatic scheme. Using multiple telescopes that will scan through a variety of wavelengths the Panchromatic project will focus its gaze on 30 stars that lay within 16 light years of our Sun.

For its second project SETI will also use a wide array of telescopes to eavesdrop on any directionless communications that may be travelling between those same 30 stars.

In fact, shows like I Love Lucy and Orson Welles’ War of the Worlds radio broadcast have been propagating throughout our galaxy long enough to have reached thousands of stars. And while we’ve been transmitting multi-channel signals for the better part of a century we’ve yet to hear from another form of intelligent life hidden among the stars.

I challenge that statement, radio or TV waves don't travel that fast. And even if they did, the power would degenerate quickly.

I also thought I read somewhere, maybe even on here in a thread somewhere that these signals fade, too, so there really couldn't be any ET's out there watching Lucy.

Depends where you go and what you read

Version 1

Number of stars within 12.5 light years = 33

Most of the stars are red dwarfs - stars with a tenth of the Sun's mass and less than one hundredth the luminosity. Roughly eighty percent of all the stars in the universe are red dwarfs, and the nearest star - Proxima - is a typical example.

Star map

Version 2

The nearest stars to Earth are in the Alpha Centauri triple-star system, about 4.37 light-years away. One of these stars, Proxima Centauri, is slightly closer, at 4.24 light-years. Of all the stars closer than 15 light-years, only two are spectral type G, similar to our sun: Alpha Centauri A and Tau Ceti.

Nearest stars

Thought 1 - Get rid of the Haystack first, and what might be left is the needle you are searching for.

Thought 2 - Are we only searching for life like us, or ANY type of life?

Thought 3 - Why are we not concentrating on Alpha Centauri A and Tau Ceti?

Thought 4 - The odds against finding anything out there are so infinitesimal as to be inconsequential.

Thought 5 - Should we still look? Hell yes! If you don't look you don't find. But being pragmatic, just don't hold your breath.

We only have one example of life and intelligence. So we don't really know what is typical for ET life, ET intelligence nor life-bearing planets. So it's better not to introduce a bias by searching for signals only from Earthlike planets. We simply don't have enough knowledge to restrict the search to only some kind of stars or planets.

If you don't provide any proof, there is no challenge.

Probably not caused by anything intelligent unless it was an advanced civilization annihilating themselves.

If Et has our level of Tec then even thou the signals we have been transmitting are weak they would still be able to be picked up with the right equipment

So Chris you never know ET might just be watching The 3 Stooges or Lucy . Would be ironic if they where Lucy did say she picked up a radio station with her fillings one day .

ET was talking to Lucy Barnet via her teeth only joking she thought it was a local radio station hehehe
