This work reviews possible signatures and potential detectability of present-day volcanically
emitted material in the atmosphere of Venus. We first discuss the expected composition of …

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 …

In the last few years astronomical surveys have expanded the reach of planetary science
into the realm of small and dense extrasolar worlds. These share a number of characteristics …

Long-standing unexplained Venus atmosphere observations and chemical anomalies point
to unknown chemistry but also leave room for the possibility of life. The unexplained …

The tentative detection of ppb levels of phosphine (PH3) in the clouds of Venus was
extremely surprising, as this reduced gas was not expected to be a component of Venus' …

This book surveys the models for the origin of life and presents a new model starting with
shaped droplets and ending with life as polygonal Archaea; it collects the most published …

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 …

Recent ground-based observations of Venus have detected a single spectral feature
consistent with phosphine (PH3) in the middle atmosphere, a gas which has been …

Context. The possible detection of phosphine (PH 3) in the clouds of Venus has raised the
question as to which processes could produce such large abundances of PH 3. Previous …

Due to its major interest for the chemistry of planetary atmospheres and exobiology,
accurate spectroscopy data of phosphine are required for the search of signatures of this …
