In the light of the recent announcement of the discovery of the potential biosignature phosphine in the atmosphere of Venus I present an independent reanalysis of the original JCMT data to assess the statistical reliability of the detection. Two line detection methods are explored, low order polynomial fits and higher order multiple polynomial fits. A non-parametric bootstrap analysis reveals that neither line detection method is able to recover a statistically significant detection. Similar to…

On the Robustness of Phosphine Signatures in Venus' Clouds
We published spectra of phosphine molecules in Venus' clouds, following open-science principles in releasing data and scripts (with community input leading to ALMA re-processing, now benefiting
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.
Constraints on a potential aerial biosphere on Venus: II. Ultraviolet radiation
Despite the harsh conditions in the atmosphere of Venus, the possibility for an aerial habitable zone exists. A thermal habitable zone is predicted to exist at an altitude range of 62 to 48 km, above
Detectability of biosignatures on LHS 1140 b
Terrestrial extrasolar planets around low-mass stars are prime targets when searching for atmospheric biosignatures with current and near-future telescopes. The habitable-zone Super-Earth LHS 1140 b
Detecting Biosignatures in the Atmospheres of Gas Dwarf Planets with the James Webb Space Telescope
Exoplanets with radii between those of Earth and Neptune have stronger surface gravity than Earth, and can retain a sizable hydrogen-dominated atmosphere. In contrast to gas giant planets, we call
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.
Exploring the Habitability of Venus: Conceptual Design of a Small Atmospheric Probe
The possible presence of life in the atmosphere of Venus has been debated frequently over the last 60 years. The discussion was recently reignited by the possible detection of phosphine (PH3), but
Hydroxide Salts in the Clouds of Venus: Their Effect on the Sulfur Cycle and Cloud Droplet pH
The depletion of SO2 and H2O in and above the clouds of Venus (45–65 km) cannot be explained by known gas-phase chemistry and the observed composition of the atmosphere. We apply a full-atmosphere

Re-analysis of the 267 GHz ALMA observations of Venus
Context: ALMA observations of Venus at 267 GHz have been presented in the literature that show the apparent presence of phosphine (PH3) in its atmosphere. Phosphine has currently no evident
Detection of the 267 GHz J = 1-0 Rotational Transition of PH3 in Saturn with a New Fourier Transform Spectrometer
Abstract In recent observations with a Fourier transform spectrometer at the Caltech Submillimeter Observatory, we have detected the highly pressure-broadened (FWHM = 11.2 GHz) J = 1-0 rotational
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.
A Precursor Balloon Mission for Venusian Astrobiology
The potential detection of phosphine in the atmosphere of Venus has reignited interest in the possibility of life aloft in this environment. If the cloud decks of Venus are indeed an abode of life,
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
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
Transfer of Life Between Earth and Venus with Planet-Grazing Asteroids
Recently, phosphine was discovered in the atmosphere of Venus as a potential biosignature. This raises the question: if Venusian life exists, could it be related to terrestrial life? Based on the
Phosphine as a Biosignature Gas in Exoplanet Atmospheres.
It is found that phosphine can accumulate to detectable concentrations on planets with surface production fluxes of 1010 to 1014 cm-2 s-1 (corresponding to surface concentrations of 10s of ppb to 100s of ppm), depending on atmospheric composition and ultraviolet (UV) irradiation.
Colonization of Venus
Although the surface of Venus is an extremely hostile environment, at about 50 kilometers above the surface the atmosphere of Venus is the most earthlike environment (other than Earth itself) in the
No phosphine in the atmosphere of Venus
The detection of phosphine (PH₃) has been recently reported in the atmosphere of Venus employing mm-wave radio observations (Greaves et at. 2020). We here demonstrate that the observed PH₃ feature
