IAUS 404: “Advancing the Search for Technosignatures” – Abstract Submission

The search for extraterrestrial life involves an effort to understand a broad range of plausible biosignatures that could arise in extraterrestrial environments. Technology is one possible consequence of planetary-scale life, which could generate “technosignatures” that could be abundant, long-lived, highly detectable, and unambiguous compared to other biosignatures.

This online symposium seeks to advance the search for technosignatures by inviting contributions on any theoretical, instrumental, observational, or data analysis ideas for characterizing and detecting technosignatures.

The goal of this symposium is to foster discussion on ways to advance the search for technosignatures by leveraging existing missions and data archives. You can visit the website for the meeting to sign up for updates and see a list of confirmed invited speakers: https://iaus404.bmsis.org/
