Methane has been proposed as an exoplanet biosignature. Imminent observations with the
James Webb Space Telescope may enable methane detections on potentially habitable …

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 …

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 …

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 …

Context. ALMA observations of Venus at 267 GHz that show the apparent presence of
phosphine (PH 3) in its atmosphere have been presented in the literature. Phosphine …
