Sorry, ET We are trying to find you, but we are not lucky.
Working on a project called “Looking for ET”, astronomers from Australia completed “the smallest and most comprehensive discovery” on more than 10 million star systems in search of technical signs of extraterrestrial culture.
Researchers used the Morchison Widefield Array (MWA) in Western Australia Australia’s Outback to scan for “technosignatures”, which could indicate the presence of a potentially advanced culture. MWA detects radio emissions at the same frequencies as FM radio frequencies.

Are there really 36 alien cultures? Well, May
“MWA is a unique telescope, a wonderfully wide field-view that allows us to observe millions of stars simultaneously,” said Chenoa Tremble, lead author of the study, in a statement. “We looked at the sky around the Vine constellation for 17 hours, which was 100 times wider and wider than before. With this dataset, we found no techno signature, no sign of a smart life. ”
TechnoSignature is defined as “potentially detectable signatures and signs of the presence of distant advanced cultures”, according to NASA. In February, the Seti organization announced that it was working on new technologies to sign technology.
To date, no presence of another culture has been found, which the researchers of the new study firmly accept.
Discovering Extraterrestrial Life ‘Probably A Longer Way to Go’, says STR Stronomer
“Our results continue to show that clearly [search for extraterrestrial intelligence] “There is still a long way to go,” the researchers wrote in the paper.
The study, which has not yet been peer reviewed, is available for reading on a preprint archive server.
However, it is hoped that the successor to the MWA, the 2 2 billion square kilometer array observatory with telescopes in South Africa and Western Australia, could detect “Earth-like radio signals” in space in the very distant future.
Steven Tinge, co-author of the study, added, Together, we will be able to survey billions of star systems, get technical signatures in the ocean of astronomy in other worlds. “
The newly published study isn’t the first to scan most of the universe’s multistars and find no signs of life. In June 2019, researchers found no evidence of extraterrestrial life among more than 1,300 stars near Earth, a prey that has been spreading for more than three years.
There should be more than 30 alien cultures in the milk pathway, according to shocking studies
A separate study, published in mid-May, suggested that not only is the “universe connected to life”, but it is a “pro-condition.”
In March, a separate study of finding life in the universe “could be normal,” considering how the constraint of life in the universe spontaneously forms across the universe.
Alien life is an absolute power, says the expert
More than 20,000,000 exoplanets have been discovered by NASA, of which about one is expected to be viable by September 0, 2018. They have the right size of star and the right orbit, at least theoretically, to support surface water and support their life. .
