The wide-field array, capable of observing millions of stars simultaneously, concentrated its search on a rather populated star region of the Vela Constellation in the southern hemisphere. For seventeen straight hours, the astronomers operating the radio interferometer listened and waited for any artificial broadcast in the FM band that could be catalogued as a "'technosignature."
With this dataset, we found no technosignatures—no sign of intelligent life. 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.
Although the observing (or rather listening) run didn't produce any tantalizing evidence of extraterrestrial activity in that part of the sky, the scientists are hopeful that the future Square Kilometre Array (SKA), a more powerful instrument that will replace the
existing array, will be able to narrow the search gap for E.T.
With the SKA, we'll be able to survey billions of star systems, seeking technosignatures in an astronomical ocean of other worlds.

A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars.
