Ammonia and Phosphine in the Clouds of Venus as Potentially Biological Anomalies
Carol E. Cleland, Paul B. Rimmer
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. The investigation of thes…
Reduced atmospheres of post-impact worlds: The early Earth
J. P. Itcovitz, A. S. P. Rae, R. I. Citron +4
Impacts may have had a significant effect on the atmospheric chemistry of the early Earth. Reduced phases in the impactor (e.g., metallic iron) can reduce the planet's HO inven…
Constraints on the production of phosphine by Venusian volcanoes
William Bains, Oliver Shorttle, Sukrit Ranjan +4
The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides eject…
Venusian phosphine: a 'Wow!' signal in chemistry?
William Bains, Janusz J. Petkowski, Sara Seager +6
The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeter-wavelength astronomical observations is extremely surprising as PH3 is an unexpected…
Starting Life and Searching for Life on Rocky Planets
Paul B Rimmer, Sukrit Ranjan, Sarah Rugheimer
The study of origins of life on Earth and the search for life on other planets are closely linked. Prebiotic chemical scenarios can help prioritize planets as targets for the searc…
Stellar versus Galactic: The intensity of energetic particles at the evolving Earth and young exoplanets
D. Rodgers-Lee, A. A. Vidotto, A. M. Taylor +2
Energetic particles may have been important for the origin of life on Earth by driving the formation of prebiotic molecules. We calculate the intensity of energetic particles, in t…
