From Eric Kvaalen, Les Essarts-le-Roi, France
I would like to nominate Ignas Snellen and his four colleagues for a Nobel prize (31 October, p 18). By concluding there is no sign of phosphine in Venus’s atmosphere, they may have saved millions of dollars, euros, pounds, roubles and I don’t know what else that were going to be spent on missions there to look for life!
