Over the last few years, we've been shifting our thinking of many "abiotic" carbonate minerals. That gives us another set of tools to look for signs of life in other planets with spectroscopic tools.

« Pint of Science » est un événement mondial durant lequel les scientifiques peuvent vulgariser leurs thématiques de recherche auprès du grand-public… dans des contextes plus que conviviaux, puisque l’événement se déroule dans des bars, autour de boissons (à consommer avec modération !).
Le 18 mai 2026, dans le bar lyonnais « House of Bears », l’équipe d’e-planets était représentée par Maxime Pineau et Victor Tricaud (en remplacement d’Élise Clavé) qui ont bien évidemment parlé de notre planète préférée : Mars !
Maxime a présenté l’évolution de notre vision de la planète rouge : depuis les dieux antiques jusqu’aux données des missions spatiales modernes, en passant par les grands épisodes des premières observations télescopiques.
L’audience, laissée sur sa faim par une grande question laissée en suspens, à savoir « Mars habitable, mais habitée par le passé ? », n’attendait plus que la seconde présentation pour être éclairée…
Deuxième sujet de la soirée présenté par Victor : la mission de la NASA Mars2020 et son fameux rover Perseverance. La clientèle du bar a pu découvrir la merveille technologique qu’est ce rover et les grands enjeux de cette mission dans le cratère Jezero. Cette soirée de vulgarisation s’est terminée par un top 3 des grandes découvertes de la mission : du quartz sur Mars, un lac dans le cratère Jezero à l’histoire complexe et tumultueuse, et enfin, des roches avec des “tâches de léopard” montrant de potentielles biosignatures !
Mais alors Victor, Mars habitable, oui, mais Mars habitée ? « Pour le savoir, il faudra ramener ces précieux échantillons prélevés par le rover sur Terre ! ».
Cette soirée Pint of Science s’est poursuivie par une longue séance de questions-réponses et discussions entre Maxime, Victor et les participants de l’événement.
Une soirée de pintes de science pleinement réussie, dans la joie et la bonne humeur: absolument à refaire !

From Andreas - “Although the likelihood of discovering simple (biosignatures) or intelligent (technosignatures) life in our galaxy is unknown, a true positive detection is expected to significantly impact society through amplification by social media & the news media.
Research in risk & science communication shows that risk perceptions and public representations of astrobiology/SETI play vital roles in how these events unfold in the public sphere.

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken from a rock named “Cheyava Falls” last year, the sample, called “Sapphire Canyon,” contains potential biosignatures, according to a paper published Wednesday in the journal Nature.

Biosignature Hype
I was thinking just the other day that I haven’t posted much in either the Astrohype or the Bad Statistics folders on this blog. Well today I found an item that belongs in both categories. Many people will have seen the widespread press coverage of a misleading claim of the discovery of alien life; see, e.g., here. This misleading press coverage is based on a misleading press release from the University of Cambridge which you can find here.
The story is based on a paper in the pay-to-publish Astrophysical Journal Letters with the title “New Constraints on DMS and DMDS in the Atmosphere of K2-18 b from JWST MIRI“. The DMS and DMDS in the title refer to Dimethyl Sulphide and Dimethyl Disulphide respectively. These are interpreted by the authors as biosignatures.
There are two main problems with this claim. One is that DMS and DMDS are not necessarily biosignatures in the first place; see here for the reasons. The other is that there isn’t even any evidence for the detection of DMS or DMDS anyway. Here is the spectrum of which the lead author of the paper, Prof. Nikku Madhusudhan, has claimed “the signal came through loud and clear”.
Yeah, right. In statistical terms this is a non-detection. The Bayes Factor used in the paper to quantify the evidence for a model with DMS and/or DMDS over one without is just 2.62. That’s not a detection by any stretch of the imagination; to be anywhere near convincing a Bayes Factor has to be at least 100. The subsequent cherry-picking of the data to improve the apparent probability of a detection is just statistical flummery.
Notice that the use of the phrase “Constraints on” in the title of the paper does not indicate that the article presents evidence that a detection has been made. That the claim has somehow morphed into the “the strongest evidence for life beyond our solar system” is absurd. The most charitable thing I can say is that Prof. Madhusudhan must have been carried away by enthusiasm. This doesn’t reflect very well on Cambridge University either.
This episode worries me greatly. This is a time of increasing hostility towards science and this sort of thing can only make matters worse. Scientists need to be much more careful in communicating the uncertainties in their results.
