WASHINGTON (Reuters) - 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.
