Telescopes can tune in to alien TV
Radio telescopes designed to study the primordial universe could also eavesdrop on extraterrestrial civilisations similar to our own. "By a happy accident," says abraham Loeb of Harvard University, "the telescopes will be sensitive to justthe kind of radio emission that our civilisation is leaking into space."
The next generation of radio telescopes are designed to pick up radio waves emitted by neutral hydrogen molecules in the early universe. These signals originally had a wavelength of 21 centimetres, but the universe has expanded since they were emitted, stretching the waves in the process. Today, these signals have a wavelength of several metres, corresponding to a frequency of tens or hundreds of megahertz. "This overlaps with our civilisation's radio emissions, which are in the range 50 to 400 megahertz," says Loeb.

Intercepted transmission from Orangelon XXII
The race appears to be threatening but not really dangerous to anyone but themselves.

I thought our radio emissions didn't really make it past Neptune.....
RA, can you give feedback on this issue?

If the others have analogous equipment, it might explain why they haven't paid us a visit. They are either expecting the Enterprise to pay them a visit, or they think we are completely nuts and have quarantined us
To: jmcenanly; All
I think they have quarantined us.. Why would they visit us with world full of screwballs and nutjobs....

The episode descriptions are even needlessly ponderous, dull, and odd. "Riker falls in love with an member of an androgynous race." "Picard must cooperate with members of a race with an incomprehensible language." "Worf must convince his son to attend school."
I didn't realize how dumb it was at the time. It's mind-blowingly bad now.
"METAPHOR!!!"

Who needs a radio telescope to pick up alien transmissions? My tin foil hat works just fine for that.

Compared to shows like BSG, Firefly, Farscape, and B5 it is mind-blowningly bad now..

B5 is still the rolls royce of television SF, even though the last season was a bit rough.
Galactica is very good but they slipped into a 'who's a cylon' game for a while and it hurt the series. The worst of BSG isn't nearly as bad as the worst of TNG - even the strange, unfunny farce episode from season one, and that odd 2nd season episode with Lee Adama and the prostitute.
I never caught the Firefly bug - I saw some and never came back. Never seen Farscape, either - maybe I should!
