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. Here we report the apparent presence of phosphine (PH 3 ) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimetre-waveband spectral detections (quality up to ~15 σ ) from the JCMT and ALMA telescopes have no other plausible identification. Atmospheric PH… 

Phosphine on Venus Cannot Be Explained by Conventional Processes.

This work thoroughly explores the potential pathways of formation of phosphine in a venusian environment, including in the planet's atmosphere, cloud and haze layers, surface, and subsurface, and provides a template for investigation of phosphines as a biosignature on other worlds.

Production of ammonia makes Venusian clouds habitable and explains observed cloud-level chemical anomalies

The model predicts that the clouds of Venus are not entirely made of sulfuric acid, but are partially composed of ammonium salt slurries, which may be the result of biological production of ammonia in cloud droplets, and predicts that they are more habitable than previously thought, and may be inhabited.

Water activity in Venus’s uninhabitable clouds and other planetary atmospheres

The recent suggestion of phosphine in Venus’s atmosphere has regenerated interest in the idea of life in clouds. However, such analyses usually neglect the role of water activity, which is a measure

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,

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

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.

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.

Venus' Mass Spectra Show Signs of Disequilibria in the Middle Clouds

Re‐examination of mass spectral data obtained from the Pioneer Venus Large Probe Neutral Mass Spectrometer reveals parent ions at varying oxidation states, implying the presence of reducing power in the clouds, and illuminating the potential for chemistries yet to be discovered.

Is Phosphine in the Mass Spectra from Venus' Clouds?

Considering the implications of the reported single spectral line detection of phosphine (PH3) by Greaves et al., we were inspired to re-examine data obtained from the Pioneer-Venus Large Probe

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.

Life in the Clouds of Venus?

WHILE the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether. As was pointed out some years ago1, water, carbon dioxide

Venus' Spectral Signatures and the Potential for Life in the Clouds

It is suggested that particles in Venus' lower clouds contain sufficient mass balance to harbor microorganisms, water, and solutes, and potentially sufficient biomass to be detected by optical methods, and warrant further investigations into the prospect of biosignatures inVenus' clouds.
