WASHINGTON — Scientists have completed the broadest search to date for extraterrestrial civilizations by scanning roughly 10.3 million stars using a radio telescope in Australia, but have found nothing – not yet, at least.

Seeking evidence of possible life beyond our solar system, the researchers are hunting for “technosignatures” such as communications signals that may originate from intelligent alien beings.

The findings were published this week in Publications of the Astronomical Society of Australia.
