The Secret Origins of the Search for Extraterrestrial Intelligence

Aliens are serious science. The search for extraterrestrial intelligence, or SETI, constitutes major research projects at radio telescopes the world over, and it is championed by the non-profit institute that shares its name. Multiple experiments on the subject, and citizen science projects like [email protected], have been going strong for decades. Every year, papers, conferences and initiatives discuss how best to seek out — and maybe even talk to — E.T.
