Sorry, ET We’re trying to find it, but no luck.
Working on a project known as “Searching for ET”, astronomers in Australia completed “the deepest and broadest search” for technological signs of extraterrestrial civilizations in more than 10 million star systems and have been found to be empty.
The researchers used the Murchison Widefield Array (MWA) in the Western Australian outback to search for “technological signatures” that could indicate the presence of an advanced civilization. The MWA looks for radio broadcasts on frequencies similar to FM radio frequencies.

ARE THERE REALLY 36 FOREIGN CIVILIZATIONS? Well maybe
“The MWA is a unique telescope, with an extraordinarily wide field of view that allows us to observe millions of stars simultaneously,” said lead study author Chenoa Tremblay in a statement. “We observed the sky around the constellation Vela for 17 hours, looking more than 100 times wider and deeper than ever. With this set of data, we did not find technological signatures, nor signs of intelligent life. “
Technosignatures are defined as “potentially detectable signatures and signals of the presence of distant advanced civilizations,” according to NASA. In February, the SETI Institute announced that it is working on new techniques to detect technology signatures.
To date, the presence of another civilization has not been found, something the researchers of the new study strongly acknowledge.
FINDING AN ALIEN LIFE ‘PROBABLY IS GOING TO TAKE A LONG TIME’, SAYS THE ASTRONOMER
“Our results continue to clearly demonstrate that [search for extraterrestrial intelligence] it has a long way to go, “the researchers wrote in the article.
The study, which has not yet been peer-reviewed, is available for reading on the arXiv preprint server.
However, there is hope that the MWA’s successor, the $ 2 billion square kilometer Array Observatory with telescopes in South Africa and Western Australia, may find “Earth-like radio signals” in space in the future. not too far away.
“Due to the increased sensitivity, the SKA low-frequency telescope to be built in Western Australia will be able to detect Earth-like radio signals from relatively nearby planetary systems,” added study co-author Steven Tingay. “With the SKA, we will be able to study billions of star systems, searching for technological signatures in an astronomical ocean of other worlds.”
The recently published study is not the first to perform a multi-star scan of much of the universe and find no sign of life. In June 2019, researchers found no evidence of extraterrestrial life among the more than 1,300 stars near Earth, a search that lasted more than three years.
THERE COULD BE MORE THAN 30 FOREIGN CIVILIZATIONS ON THE MILKWAY, SAYS A SHOCKING STUDY
A separate study published in mid-May suggested that not only is the “universe teeming with life,” it is “the favorite bet.”
In March, a separate study theorized finding life in the universe “could be common” if you consider how the building blocks of life spontaneously form throughout the universe.
ALIEN LIFE ALMOST CERTAIN, SAYS THE EXPERT
NASA has discovered more than 4,000 exoplanets, about 50 of which were believed to be potentially habitable as of September 2018. They are the correct size and orbit of their star to support surface water and, at least in theory, to support the lifetime. .
