SYDNEY (Xinhua) – In the latest attempt to prove humans are not alone in the universe, Australian astronomers scanned 10 million stars with a specially designed telescope for any possible signals emitted by alien civilisations, and despite the unprecedented effort were unable to find any trace.
Published yesterday, the research used the Murchison Widefield Array (MWA) telescope in the state of Western Australia, which can observe millions of stars simultaneously, and targetted the Vela constellation, which includes at least 10 million stars.
What astronomers were hoping to find was ‘technosignatures’, a radio emission at a frequency similar to the ones emitted by electronic devices, like mobile phones, TV and FM radio etc.
“We observed the sky around the constellation of Vela for 17 hours, looking more than 100 times broader and deeper than ever before,” co-researcher, Dr Chenoa Tremblay from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) said.
“With this dataset, we found no technosignatures, no sign of intelligent life.”
Another co-researcher, Professor Steven Tingay, from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR), said the temporary drawback won’t deter them from searching for alien civilisations in the future as they will be equipped with even more powerful telescope for the purpose, the Square Kilometre Array (SKA).
