Phosphine on Venus again…

Remember all the excitement last September about the claimed detection of Phosphine in the atmosphere of Venus? If you do you will remember that the claim has been contested. Now there is another paper on this matter claiming that what was interpreted as a spectral feature due to Phosphine (PH₃) could actually be due to Sulphur Dioxide (SO₂)). Here is the abstract of the latest paper.

You can find the full paper on the arXiv here.

P.S. I bookmarked the arXiv paper about a week ago but was very busy and forgot about it until now!
