Venus Might Be habitable Today — If Not For Jupiter
Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn’t altered its orbit around the Sun, according to new UC Riverside research. Jupiter has a mass that is […]

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 Neutral […]

Hypothesis Perspectives: Might Active Volcanisms Today Contribute To The Presence Of Phosphine In Venus's Atmosphere?
We propose an abiotic geological mechanism that accounts for the abundance of phosphine detected by Greaves et al., 2020. We hypothesize that trace amounts of phosphides formed in the mantle […]

Feasibility Analysis and Preliminary Design of ChipSat Entry for In-situ Investigation of the Atmosphere of Venus
Recent miniaturization of electronics in very small, low-cost and low-power configurations suitable for use in spacecraft have inspired innovative small-scale satellite concepts, such as ChipSats, centimeter-scale satellites with a mass […]

On The Biomass Required To Produce Phosphine Detected In The Cloud Decks Of Venus
The putative detection of phosphine in the atmosphere of Venus at an abundance of ∼20 ppb suggests that this gas is being generated by either indeterminate abiotic pathways or biological […]

The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere
We revisit the hypothesis that there is life in the Venusian clouds to propose a life cycle that resolves the conundrum of how life can persist aloft for hundreds of […]

Phosphine On Venus Cannot Be Explained By Conventional Processes
The recent candidate detection of 20 ppb of phosphine in the middle atmosphere of Venus is so unexpected that it requires an exhaustive search for explanations of its origin. Phosphorus-containing […]

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 neighbor, Venus, has cloud decks that are temperate but hyper-acidic. We report […]

Possible Marker Of Life Spotted On Venus
An international team of astronomers today announced the discovery of a rare molecule — phosphine — in the clouds of Venus. On Earth, this gas is only made industrially or […]
