Quizás lo que le faltaba al proyecto SETI par ser tomado un poco mas en serio era precisamente esto: seriedad en sus búsquedas, exploraciones mas targeteadas, dejar de buscar en el “espacio abierto” y trabajar enfocadamente sobre todos los nuevos planetas y exo-planetas que se han descubierto recientemente y las radiaciones que emiten…
In what is its most targeted search to date, the SETI Institute has scanned 86 potentially habitable solar systems for signs of radio signals. Needless to say, the search came up short (otherwise the headline of this article would have been dramatically different), but the initiative is finally offering some quantitative data about the rate at which we can expect to find radio-emitting intelligent life on Earth-like planets — a rate that’s proving to be disturbingly low.
Indeed, by the end of its survey, SETI calculated that less than one-percent of all potentially habitable exoplanets are likely to host intelligent life. That means less than one in a million stars in the Milky Way currently host radio-emitting civilizations that we can detect.
A narrow-band search
The SETI researchers, a team that included Jill Tarter and scientists at the University of California, Berkeley, reached this conclusion after scanning 86 different stars using the Green Bank Telescope in West Virginia. These stars were chosen because earlier Kepler data indicated they host potentially habitable planets — Earth-like planets that sit inside their sun’s habitable zone…
