Scan of 10.3 million stars revealed no signs of aliens – yet

WASHINGTON (Reuters) – Scientists have completed the largest discovery to date for supernatural civilizations by scanning around 10.3 million stars using a radio telescope in Australia, but nothing has been found, at least for now.

In search of evidence of possible life beyond our solar system, researchers are hunting for communication signals such as “technosigners” that may originate from intelligent alien creatures.

Using the Murchison Widefield Array (MWA) telescope on the outskirts of Western Australia, they discovered frequencies of low frequency radio emission – similar to FM radio – from stars in the constellation of Vela. The findings were published this week in the publications of the Astronomical Society of Australia.

“It is not surprising that we did not get anything. Astronomer Cheno Trambly of the Department of Astronomy and Astronomy of the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia’s national science agency, said on Wednesday that there are still many unknown variables.

“The discovery of life outside our solar system is a big challenge,” Tremble said. “We don’t know when, how, where or what kind of signs we can get to get the signal that we’re not alone in the galaxy.”

While the discovery was 100 times deeper and wider than before, according to astronomer Steven Tinge of Curtin University in Australia and the International Center for Radio Astronomy Research, it contained relatively few stars in cosmic terms.

“Ten million stars feel a lot. However, our best assessment is that there are about 100 billion stars (in the Milky Way galaxy). So we have seen only 0.001% of our galaxy. “There were only 30 fish to intercept the seas and we tried to look for them by testing the size of a backyard swimming pool. It would have been very unlikely to find one of those fish. ”

MWA is the precursor to another device, the Square Kilometer Array (SKA), which promises to promote the discovery of technosignitions in the near future.

“What’s important is constantly improving techniques and always going deeper and further,” Tinge said. “There is always a chance that the next observation will be the one that changes something, even if you don’t expect anything. Science can surprise, so the important thing is to keep looking. ”
