Sorry, ET We’re trying to find you, but we have no luck.
Working on a project known as “ET Searching,” Australian astronomers have completed the “deepest and widest search” looking for technological signs of extraterrestrial civilizations in more than 10 million star systems and empty thought.
Researchers used the Murchison Widefield Array (MWA) outside Western Australia to scan “technosignatures” that could indicate the existence of an advanced civilization. MWA is looking for radio broadcasts at frequencies similar to FM radio frequencies.
ARE THERE REALLY 36 ALIEN CIVILIZATIONS HERE? SIGURO
“The MWA is a unique telescope, with an extremely wide field of view that allows us to observe millions of stars at once,” the study’s lead author Chenoa Tremblay said. in a statement. “We looked at the sky around the Vela constellation for 17 hours, looking over 100 times wider and deeper than ever before. In this dataset, we found no technosignatures – no signs of intelligent life. ”
The technology has been defined as “potentially visible signatures and signals of the existence of distant advanced civilizations,” according to NASA. In February, the SETI Institute announced it was working on new techniques to see technosignatures.
So far, no other civilization has been found, something that researchers have strongly acknowledged in the new study.
LOOKING FOR EXCESSIVE LIFE ‘MAY LAST,’ SAYS ASTRONOMER
“Our results clearly show that [search for extraterrestrial intelligence] there is still a long way to go, “the researchers wrote on paper.
The study, which has not yet been peer reviewed, is available to read on the preprint arXiv server.
However, it is hoped that the successor to MWA, the $ 2 billion square Kilometer Array observer with telescopes in South Africa and Western Australia, will find “Earth-like radio signals” in space in the not too distant future .
“Due to the increasing sensitivity, the SKA low-frequency telescope to be built in Western Australia is capable of detecting Earth-like radio signals from relatively nearby planetary systems,” added the co-author of student Steven Tingay. “At SKA, we will be able to survey billions of star systems, looking for technosignatures in an astronomical ocean of other worlds.”
The newly published study was not the first to make a multistar scan of a large part of the universe and did not find any signs of life. In June 2019, researchers found no evidence of extraterrestrial life among more than 1,300 stars near Earth, a hunt that lasted more than three years.
MAY BE MORE THAN 30 ALIEN CIVILIZATIONS ON THE MILKY WAY, SHOCKING STUDY SAYS
A separate study published in mid-May suggested that not only is the “universe full of life” but it is “the favored bet.”
In March, a separate study had the theory of finding life in the universe that “could be commonplace” considering how life blocks are formed spontaneously across the universe.
ALIEN’S LIFE IS A ALMOST CERTAINTY, EXPERT SAYS
NASA has discovered more than 4,000 exoplanets, about 50 of which are believed to be habitable in September 2018. They have the right size and orbit of their star to support surface water and, at least theoretically , to support life.
