Alex Akins is a technologist at NASA-JPL and leads a paper that describes the analysis of recalibrated data taken with the ALMA instrument. The team cannot confirm that the presence of phosphine in Venus’ atmosphere.
Vikky Meadows, Professor at the University of Washington and Drake Award recipient, is a co-author on an additional paper showing that the spectral signatures originally attributed to phosphine in the Venus clouds are more likely explained by the presence of sulfur dioxide in Venus’ upper atmosphere.
