Is there life on Mars Venus?

 


There's an interesting story floating around today about a scientific observation that there's Phosphine (a gaseous chemical compound) in the atmosphere of Venus. The interesting bit is that the only we we know (other than in a lab) that Phosphine is made is via life processes (for example in the digestive tract of Penguins or via bacterial digestion) Since we're pretty sure that there are no chemistry labs or Penguins on Venus then perhaps there are microbes? Since the surface of the planet is far to hot to host life (400 degrees Centigrade) it's been postulated that perhaps the microbes are floating around in the thick clouds that shroud the planet at an altitude of around 50 km, it's plausible since the temperature at that height is fine for life as we know it (i.e. 20-30 Centigrade). The only problem with the life on Venus hypothesis is that the atmosphere is highly acidic, being made up of around 60-70% Sulfuric acid which is hardly conducive to living things as we know them. Maybe life has evolved there to be so different from life on Earth that such a hostile environment can be endured but it seems unlikely, or maybe there is some, as yet, unknown geo-physical process going on that produces PH3 (Phosphine) - time will tell.
