Researchers detected no communications from extraterrestrial life after using a radio telescope in outback Western Australia to scan at least 10 million stars systems for signals of alien frequencies.
In a new paper published this month in the journal Publications of the Astronomical Society of Australia, astronomers at the the Astronomical Society of Australia describe using the Murchison Widefield Array (MWA) telescope to explore the sky around the Vela constellation, which is visible in the southern celestial hemisphere.
“We observed the sky around the constellation of Vela for 17 hours, looking more than 100 times broader and deeper than ever before … With this dataset, we found no technosignatures – no sign of intelligent life,” Tremblay added.
Technosignatures refer to radio emissions at frequencies similar to those used in FM radio broadcasts, which could signal the presence of intelligent life.
“As Douglas Adams noted in ‘The Hitchhiker’s Guide to the Galaxy,’ ‘space is big, really big,’” Tingay said.
“And even though this was a really big study, the amount of space we looked at was the equivalent of trying to find something in the Earth’s oceans but only searching a volume of water equivalent to a large backyard swimming pool,” he added.
