00:00Our search for life out in the cosmos has thus far turned up, well, nothing.

00:08But there is almost certainly life out there somewhere, even if it's just some extraterrestrial bacteria.

00:13But until we can get boots, or at least the treaded wheels of a rover on the surface of those planets most likely to have life,

00:19we'll likely never be able to confirm it.

00:21That is, of course, unless that life is intelligent, and that life is like that of Earth's,

00:25and constantly sending technosignatures out into space.

00:28And that's exactly what radio-sensing programs like SETI, or the Search for Extraterrestrial Intelligence program, is doing.

00:34SETI has detected a number of possible alien broadcasts over the years,

00:38but follow-ups on those have been unable to produce confirmation of extraterrestrial life.

00:42And that's probably because alien life, or at least intelligent alien life,

00:46probably hasn't occurred in Earth's general cosmic vicinity.

00:49Enter the Galileo Project.

00:50The program is only looking for aliens in terms of hard evidence,

00:54meaning they're looking to investigate interstellar objects in space,

00:57or those that fall to Earth for signs of life,

00:59and looking at unidentified aerial phenomena that occur in infrared, radio, and optical bands,

01:04and those that are able to be recorded via audio data,

01:07meaning looking at observable data most likely to be exhibited and produced by aliens

01:12that are on the same technological level as humans.

01:15implicitly would have been vídeo-level areas in the building Muscle English

01:32following the ideas were coded by aliens as humans.

01:43You remember us today.
