What a Signal in a Failed Star’s Clouds Means for the Search for Life
The detection of the molecule #phosphine in a #browndwarf’s atmosphere may help #astronomers in their search for life elsewhere in the Milky Way,a molecule that on this planet is produced by living things.
This discovery is not life, the astronomers say. Any life as we know it would be impossible to sustain in such an environment.

"Venus: extant microlife?" A 15-minute talk Jane Greaves gave yesterday begins on https://www.youtube.com/watch?v=bC44HHGwRJ4#t=5h57m48s at 5:57:48. She reported - at the meeting https://www.physics.ox.ac.uk/research/group/breakthrough-listen/breakthrough-discuss-2024 - on lots more #phosphine detections in the #Venus atmosphere, plus some indications of #ammonia, too - which together *may* have something to do with the metabolism of airborne microorganisms. After the talk she actually let shape models of such creatures fly through the hall ...

Life could exists in the clouds on Venus, I've read. Or vast underwater oceans within the moons of the outer planets.

#CHNOPS stands for #Carbon, #Hydrogen, #Nitrogen, #Oxygen, #Phosphorus, and #Sulfur. These six elements make up 98% of living matter on Earth! How does that help you? If you understand the chemical behavior of CHNOPS, you can understand almost all of biochemistry.

Phosphine is playing peekaboo from the Venusian atmosphere again so I’m just going to leave this here.

#Phosphine #Venus #Astrodon

Once again, a chemical associated with life in the atmosphere of #Venus has been detected. At last week's National Astronomy Meeting in the UK, researchers said they detected #phosphine in the atmosphere of Venus using the James Clark Maxwell Telescope. The same team announced the discovery of phosphine at Venus in 2020 using both that telescope as well as the Atacama Large Millimeter/submillimeter Array. However, other scientists have been unable to replicate the findings.

Des scientifiques ont trouvé de la #phosphine[1] dans l'atmosphère de #Vénus[2].

De ce que j'en comprends, la phosphine est produite en laboratoire ou par des microbes. Elle est donc considérée comme une #biosignature[3].

Soit on comprend très mal Vénus et c'est un phénomène qu'on a pas identifié, soit il y a de la vie sur Vénus. J'ai pas de smiley pour dire à quel point je suis impatient d'en savoir plus.

Does anypony know why one of our senior scientists was talking to us this afternoon about #phosphonium #ylide and #triphenylphosphine?

Are #phosphoniumylide and #triphenyl #phosphine better #hashtags?

@mona, your input would be appreciated.
