Feb 4, 2025 by News Staff

The field of SETI searches for technosignatures could provide the first detection of life beyond Earth through the technology that an extraterrestrial intelligence may have created. Any given SETI survey, if no technosignatures are detected, should set upper limits based on the kinds of technosignatures it should have been able to detect; the sensitivity of many SETI searches requires that their target sources emit with power far exceeding the kinds...
