The appearance of this kind of molecule related to life on Earth on Venus has also caused a great scientific and media sensation, but its existence in the atmospheres of Jupiter and Saturn has a history of decades, even in some stars. be found. CSIC researchers were the first to discover it outside our solar system. Now they value the new discoveries of SINC.
Phosphorus (represented by the symbol P in the periodic table of elements) is closely related to life, because it is the main biogenic element, that is, it exists in all known life forms.However, little is known about him Chemical evolution In the universe.
Only detected Six phosphorus molecules in space (PN, PO, C2 pcsP, CP and HCP are five of them, the last two are determined by Spanish scientists), including phosphine, Officially named fosfano (PH3), This is a stable hydride of phosphorus.
For decades, people have known that phosphine exists in the atmosphere. Saturn ÿ Jupiter, Simultaneously Gas giant, The molecule formed in the deep layer and was dragged to the upper layer.Researcher Juan R. Pardo One of CSIC’s analysts used data from the old Caltech submillimeter observatory in Hawaii for analysis.

If we go outside the solar system, only phosphine will be detected The wind of certain stars (The red giant pulses periodically, and part of the mass is ejected in the process), but the mechanism of their formation in these areas is unclear.
Possible Phosphorus Reserves in Comets
Regarding the recent detection of phosphine in the clouds Venus, This week’s publication New research, Another puzzle about the chemical evolution of phosphorus in the universe has been added.
Unlike Jupiter and Saturn, where the atmosphere is reductive (where phosphine is preferred), Venus has an oxidizing acidic atmosphere, and such gases should react quickly and survive only for a short period of time.
But it appeared. So the question is what mechanism can produce PH3 Fast enough to counteract the rate of destruction and maintain the observed abundance?
There is currently no answer. It is very likely that the source of the phosphine from the microorganisms is suggestive, but it is more likely that an unidentified chemical or geochemical mechanism is responsible for the existence of this gas in the atmosphere of our neighboring planet.
