WA CSIRO and Curtin University study finds no signs of alien life in search of 10 million star systems
We might never know if humans are all alone in the universe – but a new study by WA astronomers suggests that if we do have neighbours, they’re pretty well hidden.
CSIRO astronomer Dr Chenoa Tremblay and Curtin University Professor Steven Tingay used the Murchison Widefield Array telescope to search for radio emissions that could come from other civilisations.
Their study, published this week in Publications of the Astronomical Society of Australia, surveyed a patch of sky containing at least 10 million star systems.
Despite the huge sample area, it didn’t find any signs of alien life.
The result does not deter Professor Tingay.
“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 said.
“We have to keep looking.”
We have to keep looking.
A new observatory is being built that will be capable of scanning billions of star systems.
The Square Kilometre Array (SKA) will have telescopes in WA and South Africa, and will be 50 times as sensitive as its predecessors.
