A Question of Phosphine

Posted in Astrohype, The Universe and Stuff with tags , , , on October 21, 2020 by telescoper

Remember all the excitement last month about the claimed detection of phlogiston phosphine in the atmosphere of Venus?

Well, a wet blanket appears to have been thrown over it by a new paper on the arXiv by Snellen et al. Here is the abstract:

The conclusions are very clear, but the paper hasn’t been refereed yet. Let’s see what the authors of the original work have to say. For myself, I think a proper (i.e. Bayesian) analysis of the data is called for…

I should also mention in this context another paper on the arXiv from a few days ago, which uses a null detection to place an upper limit on the phosphine abundance.

Note that one of the authors of this second paper is Jane Greaves, who was on the original discovery paper.

Today’s Big Astronomy Announcement

Rumours have been circulating for a few days about a big astronomical discovery. Here is a video of the announcement:

Sorry, that’s the wrong video.

The actual announcement will take place live at 4pm BST here:

Until a few minutes ago I didn’t have a clue what this was about, but now I do…

If you would like to read more about this discovery then you can read the paper in Nature here. Several of the authors are former Cardiff colleagues, including first author Jane Greaves, as well as Annabel Cartwright and my former office mate Emily Drabek-Maunder. Congratulations to them on an exciting result!

P.S. Emily reminded me last night that I was present at the discussion with Jane that started this project, over four years ago. I remember them talking about phosphine but had no idea that it would lead to this!
