Discovering evidence of life beyond Earth would attract extraordinary public attention, but the scientific evidence is unlikely to arrive as a single, unambiguous moment of discovery. Scientists, journalists, communicators, historians and philosophers gathered at a Lorentz Center workshop to consider how the search for life elsewhere should be communicated as evidence develops. Their recommendations emphasise transparency about uncertainty, realistic expectations, independent verification, careful use of language and imagery, and sustained public engagement. The resulting paper argues that preparing for communication before a potential discovery occurs will be essential for maintaining scientific rigour and public understanding.
