Venusian phosphine: a 'Wow!' signal in chemistry?

William Bains, Janusz J. Petkowski, Sara Seager +6

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…

UV Transmission in Natural Waters on Prebiotic Earth

Sukrit Ranjan, Corinna L. Kufner, Gabriella G. Lozano +3

Ultraviolet (UV) light plays a key role in surficial theories of the origin of life, and numerous studies have focused on constraining the atmospheric transmission of UV radiation…

Starting Life and Searching for Life on Rocky Planets

Paul B Rimmer, Sukrit Ranjan, Sarah Rugheimer

The study of origins of life on Earth and the search for life on other planets are closely linked. Prebiotic chemical scenarios can help prioritize planets as targets for the searc…

Low levels of sulphur dioxide contamination of Venusian phosphine spectra

Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards +7

New analysis is presented of the 1.1 mm wavelength absorption lines in Venus' atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from th…

Assessment of Ammonia as a Biosignature Gas in Exoplanet Atmospheres

Jingcheng Huang, Sara Seager, Janusz J. Petkowski +2

Ammonia (NH3) in a terrestrial planet atmosphere is generally a good biosignature gas, primarily because terrestrial planets have no significant known abiotic NH3 source. The condi…

Recovery of Spectra of Phosphine in Venus' Clouds

Jane S. Greaves, Anita M. S. Richards, William Bains +7

We recover PH3 in the atmosphere of Venus in data taken with ALMA, using three different calibration methods. The whole-planet signal is recovered with 5.4σ confidence using Venus…
