"By varying the parameters of our simulations, we were able to explain this detection and non-detection of methane on Mars and understand the conditions and locations in which they can occur. This is an important step towards clarifying the association of methane on Mars with the possible existence of life," explains Pedro Machado , co-author of this study.
Also included in this study, phosphine can be spontaneously produced in high pressure and temperature environments in the presence of phosphorus and hydrogen, the two chemical elements that constitute it.
So, when in 2020 a study identified phosphine in the clouds of Venus, the scientific community turned its attention to this planet."Further studies carried out under other conditions showed that phosphine may not be present after all or be present in much smaller amounts than initially identified, something that we were also able to reproduce," adds Pedro Machado.is very important for us to know if there is volcanic activity.
