NASA has a new approach to alien hunting, which involves searching the stars for evidence of advanced technologies.
In the past, NASA has focused its research on extraterrestrial life in search of signs of biological activity. Now, they have a new idea. The space agency expands its quest for extraterrestrial life in search of "technosignatures" Fox News reported Friday.
"Technosignatures are signs or signals that, if observed, would infer the existence of technological life elsewhere in the universe," NASA said.
According to NASA, the most obvious radio signals are radio signals, although the agency noted that "many more have not been fully explored."
As NASA has explained, technosignatures could be found in the least expected places. A planet charged with an "atmosphere full of pollutants" might not seem like the ideal cradle of alien life, but it could imply that an industrial civilization falls under the smog.
Similarly, NASA stated that it kept its eyes open to other unusual signs of advanced alien life, such as "laser emissions" and even "signs of massive structures".
The latter may seem exaggerated, but it is a sign of the public interest wave that Tabby's Star has been stirring since 2015.
"Kepler's discovery in 2015 of irregular fluctuations in brightness in what was to be known as Tabby's Star led to the speculation of an extraterrestrial megastructure," NASA said.

When irregular gradation was first discovered, the researchers suggested that there was a slight chance that it was caused by the construction of a gigantic device designed to recover energy from the star.
"We have never seen anything like this star," said Tabetha Boyajian of Yale University. L & # 39; Atlantic at the time.
It was really weird. We thought it might be bad data or a movement on the spacecraft, but everything was checked.
Since, The Guardian Astronomers have reported that Tabby's Star is almost certainly surrounded by an exceptionally massive cloud of dust.
Unusual life but not extraterrestrial.
It is not because aliens were not extraterrestrials that NASA suggested that cases like Tabby's Star were not worth scrutinizing.
"Tabby's Star has demonstrated the potential utility of looking for anomalies in data collected in space, as the signs of a technologically advanced life may appear to be aberrations from the norm," the agency said.
In other words, NASA is trying to use its imagination, although the agency pointed out that an unexplained anomaly was not enough to prove the existence of strangers.
"Scientists warn that we will need more than an unexplained signal to definitely prove the existence of technological life," NASA said.
If you want to search for extra-terrestrial life, you can connect to NASA's Technosignatures workshop. The workshop will be broadcast live from Houston throughout Friday.
