No Technosignature Detected on K2-18b; Study Advances Search Methods and Astrobiology Integration
To the point
While no convincing technosignatures were found on K2-18b with the VLA and MeerKAT, Tremblay and Bennett say the work shows how such searches fit into broader life-detection efforts and clarifies that current telescopes can only detect exceptionally strong transmissions, making a detection from any one planet very unlikely.
