Scientists Propose a Smarter Way to Hunt for Alien Radio Signals
The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research suggests refining our search parameters by using our own broadcasts into deep space as a helpful guide. Research published earlier this week in Astrophysical Journal Letters suggests we search for alien signals by studying how we beam strong, directed transmissions during two-way communication with our de
