Phosphine in the Venusian Atmosphere: A Strict Upper Limit from SOFIA GREAT Observations
M. A. Cordiner, G. L. Villanueva, H. Wiesemeyer +13
The presence of phosphine (PH) in the atmosphere of Venus was reported by Greaves et al. (2021a), based on observations of the J=1-0 transition at 267 GHz using ground-based, m…
No evidence of phosphine in the atmosphere of Venus by independent analyses
Geronimo Villanueva, Martin Cordiner, Patrick Irwin +24
The detection of phosphine (PH3) in the atmosphere of Venus has been recently reported based on millimeter-wave radio observations (Greaves et al. 2020), and its re-analyses (Greav…
Synergies between ground-based and space-based observations in the solar system and beyond
Vincent Kofman, Chris Moeckel, Glenn Orton +12
Telescope and detector developments continuously enable deeper and more detailed studies of astronomical objects. Larger collecting areas, improvement in dispersion and detector te…
The Crucial Role of Ground- and Space-Based Remote Sensing Studies of Cometary Volatiles in the Next Decade (2023-2032)
Nathan X. Roth, Dennis Bodewits, Boncho Bonev +15
The study of comets affords a unique window into the birth, infancy, and subsequent history of the solar system. There is strong evidence that comets incorporated pristine interste…
Planetary Spectrum Generator: an accurate online radiative transfer suite for atmospheres, comets, small bodies and exoplanets
Geronimo L. Villanueva, Michael D. Smith, Silvia Protopapa +2
We have developed an online radiative-transfer suite (https://psg.gsfc.nasa.gov) applicable to a broad range of planetary objects (e.g., planets, moons, comets, asteroids, TNOs, KB…
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
C. Snodgrass, M. F. A'Hearn, F. Aceituno +112
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67…
