What technology could help find alien life?
What potential technologies for communication are out there that we are NOT using. Obviously there are optical and radio telescopes. Is there anything else we could try?
Well, we're using the radio part of the spectrum and the optical part of the spectrum. We'd like to take our techniques into the infrared. There's less absorption and scattering by dust between the galaxies in the infrared than there is in the optical. And basically, none of our experiments do a really good job at transient signals, things that just go bump in the night once. We know how to do that search. It just takes more computer power than we have on Earth at the moment.
