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 […]

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 […]
