In the atmosphere of Venus, scientists find gas associated with life
Phosphine, released from oxygen-starved environments by microbes was more than predicted in amounts.
Traces of pungent gas flowing through the Venus clouds can be pollution from aerial species-but not, as we know, from microbial life.
Phosphine has been found 30 miles into the air of the earth, and a mechanism that is other than life that is responsible for its presence has yet to be identified.
The discovery gives rise to the potential for life to become a part of the Earth 's inner neighbor and remnants to live – or to float, at least – as Venus experienced a fugitive global warming that enlightened the world.
Venus has been temperate for 2bn years and has been harboring the ocean. Today, however, a thick atmosphere of carbon dioxide blanket an almost waterless earth, with top 450C. The sky's clouds have 90% sulphuric acid, and they are not welcoming.
Venus conditions are so overwhelmingly toxic that many observers consider the world is dead. They believe that phosphine comes from more conventional processes rather than floating Venusians.
According to Professor Jane Greaves, Cardiff University astronomer and team leader who made the find, it is quite shocking to think that life could exist with too much sulfuric acid, but all the geologic and photochemical routes that we can imagine are much too bad to produce phosphine that we see. It is quite surprising.
On Earth, bacteria, such as lake sediments or animal indoors release phosphine gas to hungry oxygen. Other development processes – Jupiter and Saturn's bowels – are so intense that phosphine is known to be a source of life on rocky planets.
I’m quite sure that we are not alone in this universe. But, at least are we alone in this solar system?
