Effect Of Clouds On Emission Spectra For Super Venus
We report a model study on the effects of clouds on emission spectra of super-Venus planets. Our goal is to assess possible ways to identify characteristic spectral features due to […]

Constraints On The Production Of Phosphine By Venusian Volcanoes
The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides ejected […]

Venusian Phosphine: A 'Wow!' Signal In Chemistry?
The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeter-wavelength astronomical observations is extremely surprising as PH3 is an unexpected component of an oxidized environment […]

DAVINCI Venus Mass Spectrometer
DAVINCI will send a meter-diameter probe to brave the high temperatures and pressures near Venus’ surface to explore the atmosphere from above the clouds to near the surface of a […]

Day-night Cloud Asymmetry Prevents Early Oceans On Venus But Not On Earth
Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5-3.8 billion years ago. However, it is still unknown whether water has ever condensed on […]

Climate Model Shows That Venus Could Never Have Had Oceans
Whether Venus, one of the Solar System’s four terrestrial planets, ever had oceans remains an unsolved puzzle. Although an American study hypothesized that it did, this is now challenged in […]

Study Finds Photosynthesis in Venus' Clouds Could Support Life
New data analysis has found that the sunlight filtering through Venus’ clouds could support Earth-like photosynthesis in the cloud layers and that chemical conditions are potentially amenable to the growth […]

Early Habitability And Crustal Decarbonation Of A Stagnant-lid Venus
Little is known about the early evolution of Venus and a potential habitable period during the first one billion years. In particular, it remains unclear whether or not plate tectonics […]

Low Levels of Sulphur Dioxide Contamination of Phosphine Spectra from Venus' Atmosphere
New analysis is presented of the 1.1 mm wavelength absorption lines in Venus’ atmosphere that suggested the presence of phosphine. We confirm that ALMA detected absorption at the PH3 1-0 […]
