We first respond to two points raised by Villanueva et al. We show the JCMT discovery spectrum of PH3 can not be re-attributed to SO2, as the line width is […]

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 […]

Re-analysis Of The 267-GHz ALMA Observations of Venus: No Statistically Significant Detection Of Phosphine
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 […]

A Stringent Upper Limit Of The PH3 (Phosphine) Abundance At The Cloud Top Of Venus
Following the announcement of the detection of phosphine (PH3) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molecule in the […]

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 […]
