Venusian phosphine: a ‘wow!’ signal in chemistry?
The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeterwavelength astronomical observations is extremely surprising as PH3 is an unexpected component of anExpand
Experimental and Computational Studies on the Physicochemical Behavior of Phosphine Induced by Reactions with H and D Atoms on Interstellar Ice Grains
Phosphine (PH3) is an important molecule in the chemistry of phosphorus (P)-bearing species in the interstellar medium. Interstellar PH3 is thought to primarily form on icy grains, where severalExpand
Was Venus Ever Habitable? Constraints from a Coupled Interior–Atmosphere–Redox Evolution Model
Venus’s past climate evolution is uncertain. General circulation model simulations permit a habitable climate as late as ∼0.7 Ga, and there is suggestive—albeit inconclusive—evidence for previousExpand

Recovery of Spectra of Phosphine in Venus' Clouds
We recover PH3 in the atmosphere of Venus in data taken with ALMA, using three different calibration methods. The whole-planet signal is recovered with 5.4σ confidence using Venus bandpassExpand
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.Expand
A stringent upper limit of the PH3abundance at the cloud top of Venus
Following the announcement of the detection of phosphine (PH$_3$) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molecule in the infraredExpand
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 ProbeExpand
Venus' Mass Spectra Show Signs of Disequilibria in the Middle Clouds
TLDR
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. Expand
Submillimeter mapping of mesospheric minor species on Venus with ALMA
Abstract Millimeter and submillimeter heterodyne spectroscopy offers the possibility of probing the mesosphere of Venus and monitoring minor species and winds. ALMA presents a unique opportunity toExpand
Detection of CH3C3N in Titan’s Atmosphere
Titan harbors a dense, organic-rich atmosphere primarily composed of N$_2$ and CH$_4$, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high sensitivity observationsExpand
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.Expand
