HOW VENUS BECAME COOL: SOCIAL AND MORAL DIMENSIONS OF BIOSIGNATURE SCIENCE
Zygon, 2021 A 2020 scientific report indicated the presence of phosphine, a potential biosignature chemical, in the atmosphere of Venus. As a result, Venus instantly became a global cultural celebrity.

Ammonia and Phosphine in the Clouds of Venus as Potentially Biological Anomalies
Aerospace, 2022 We are of the opinion that several anomalies in the atmosphere of Venus provide evidence of yet-unknown processes and systems that are out of equilibrium.

False Biosignatures on Mars: Anticipating Ambiguity [PDF]
, 2021 It is often acknowledged that the search for life on Mars might produce false positive results, particularly via detections of objects, patterns or substances that resemble the products of life in some way but are not biogenic.

A Statistical Approach to Illustrate the Challenge of Astrobiology for Public Outreach
Life, 2017 In this study, we attempt to illustrate the competition that constitutes the main challenge of astrobiology, namely the competition between the probability of extraterrestrial life and its detectability.

Degradation of microbial fluorescence biosignatures by solar ultraviolet radiation on Mars [PDF]
, 2014 Recent and proposed robotic missions to Mars are equipped with implements to expose or excavate fresh material from beneath the immediate surface. Once brought into the open, any organic molecules or potential biosignatures of present or past life will ...

Identifying Molecules as Biosignatures with Assembly Theory and Mass Spectrometry
, 2020 The search for evidence of life elsewhere in the universe is hard because it is not obvious what signatures are unique to life. Here we postulate that complex molecules found in high abundance are universal biosignatures as they cannot form by chance. To
