The recent candidate detection of ∼1 ppb of phosphine in the middle atmosphere of Venus is so unexpected that it requires an exhaustive search for explanations of its origin. Phosphorus-containing species have not been modeled for Venus' atmosphere before, and our work represents the first attempt to model phosphorus species in the venusian atmosphere. We thoroughly explore the potential pathways of formation of phosphine in a venusian environment, including in the planet's atmosphere, cloud…

Phosphine gas in the cloud decks of Venus

Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic.

Venusian phosphine: a ‘wow!’ signal in chemistry?

Abstract 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 component

Volcanically extruded phosphides as an abiotic source of Venusian phosphine

It is concluded that volcanism could supply an adequate amount of phosphide to produce phosphine and is supported by remote sensing observations of the Venusian atmosphere and surface that have been interpreted as indicative of currently active volcanism.

Recovery of Phosphine in Venus' Atmosphere from SOFIA Observations

Searches for phosphine in Venus’ atmosphere have sparked a debate. Cordiner et al. 2022 analyse spectra from the Stratospheric Observatory For Infrared Astronomy (SOFIA) and infer <0.8 ppb of PH 3 .

Ammonia and Phosphine in the Clouds of Venus as Potentially Biological Anomalies

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 these anomalies on

Volcanically extruded phosphides as an abiotic source of Venusian phosphine

We hypothesize that trace amounts of phosphides formed in the mantle are a plausible abiotic source of the Venusian phosphine observed by Greaves et al. [ Nat. Astron. (2020)]. In this hypothesis,

Constraints on the Production of Phosphine by Venusian Volcanoes

The initial reports of the presence of phosphine in the cloud decks of Venus have led to the suggestion that volcanism is the source of phosphine, through volcanic phosphides ejected into the clouds.

Phosphine in the Venusian Atmosphere: A Strict Upper Limit From SOFIA GREAT Observations

The presence of phosphine (PH3) in the atmosphere of Venus was reported by Greaves et al. (2021, https://doi.org/10.1038/s41550-020-1174-4), based on observations of the J = 1–0 transition at 267 GHz

On The Biomass Required To Produce Phosphine Detected In The Cloud Decks Of Venus

The detection of phosphine in the atmosphere of Venus at an abundance of $\sim 20$ ppb suggests that this gas is being generated by either indeterminate abiotic pathways or biological processes. We

Exobiology of the Venusian Clouds: New Insights into Habitability through Terrestrial Models and Methods of Detection.

To detect putative venusian organisms, potential biosignature detection methods are described, which include metal-microbial interactions and optical methods, and currently available technology that can potentially be used for modeling and simulation experiments are described.

Claimed Detection of PH3 in the Clouds of Venus Is Consistent with Mesospheric SO2

The observation of a 266.94 GHz feature in the Venus spectrum has been attributed to phosphine (PH3) in the Venus clouds, suggesting unexpected geological, chemical, or even biological processes.

The Case (or Not) for Life in the Venusian Clouds

The environmental conditions in the lower Venusian atmosphere is characterized and what challenges a biosphere would face to thrive there, and how some of these obstacles for life could possibly have been overcome, and an assessment on whether life may exist in the temperate cloud layer of the Venusian Atmosphere or not is provided.
