PRESS RELEASE DATE February 3, 2025 CONTACT Rebecca McDonald Director of Communications, SETI Institute rmcdonald@seti.org Screen capture of “Earth detecting Earth” animation video. ONLINE February 3, 2025, Mountain View, CA – A research team led by Dr. Sofia Sheikh Press Release/Images of the SETI Institute, in collaboration with the Characterizing Atmospheric https://bit.ly/3X5KXIH Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to answer a simple question: If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away? Researchers used a theoretical, modeling-based method, and this study is the first to analyze multiple types of technosignatures together rather than separately. The findings revealed that radio signals, such as planetary radar emissions f
