is helping them search for more sensitive signals than they ever have before.
SETI efforts have honed in on what they call “beacon” signals. These are a type of signal that an intelligent civilization might create to indicate to other potential lifeforms that they exist, and that they are open for visitors. Technically speaking, the FFA technique helps search for periodic signals with shorter duty cycles, something that is hard to capture via previous methods.
However, the new software enables researchers to look out for pulsating narrowband signals, which compared to continuous signals are more energetically efficient and therefore might be a better option to use as a beacon.Read More:While it might be more realistic for SETI investigators to identify a beacon signal, there is another class of signals that could indicate the presence of an intelligent, technologically advanced civilization. These are called “leakage” signals.
“They might employ highly complex signal modulation methods that, to a common observer, could resemble noise,” Gajjar says.Lack of Knowledge About Alien Technology
