New exoplanet-informed research sets clearer bounds on the search for radio technosignatures A new study leverages the NASA Exoplanet Archive and planetary system simulations to make narrowband SETI searches more efficient. PRESS RELEASE DATE October 23, 2023 CONTACT Rebecca McDonald Director of Communications, SETI Institute rmcdonald@SETI.org ONLINE Press Release/Images https://bit.ly/3rStlUf Image credit: Zayna Sheikh October 23, 2023, Mountain View, CA — In a new study published in the Astronomical Journal, researchers used the known population of exoplanets and extrapolated to the much larger, unknown population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). The prior recommendation for the threshold “drift rate” contribution, caused by a planet’s motion around its host star, was 200 nHz. In this work, lead author Megan Grace Li and her team found that 53 nHz was sufficient in 99% of known-exoplanet cases and tha
