Life on Venus ?

over 3 years ago

In 1967 Carl Sagan published an article where he speculated that some kind of bacterial life could exist in the sky of the planet Venus, it is understood that on the surface of the planet it is very difficult for the condition of life to occur but in the clouds of the planet Carl Sagan He said it was possible, more than 50 years later Carl Sagan's theory is confirmed, scientists have found phosphine in the atmosphere of Venus.

An article was published in the journal Nature explaining that in 2017 the Hawaiian telescope, collecting data from Venus, found the presence of phosphine in the atmosphere. Therefore, an investigation was carried out with the ALMA telescope in Chile to verify the data.

Phosphine is a simple molecule that is made up of 3 hydrogen atoms and one phosphorus, it is toxic and very simple, there are few non-biological mechanisms that can produce this molecule, so it is speculated that living organisms exist on Venus.

The way scientists search for life on other planets is through biomarkers and phosphine is a biomarker, there is no way for scientists to look at the surface of a planet and see animals jumping, we can't even see the surface of Venus our closest neighbor, there are only a few photos of the surface of a mission that they sent a long time ago, so it is understood that living organisms modify the atmosphere of a planet that is why these biomarkers are looked for in the atmosphere.

The way in which the observation is made by the telescopes worked similar to a radio on earth, the observers change the frequency and can see different molecules in the atmosphere because they know what frequency each molecule belongs to.

From here, it only remains to speculate, but it can be summed up to 2 possibilities, or phosphine is produced by a means that we are totally unaware of or it is produced by living beings, perhaps microorganisms on the planet Venus exist, Venus has temperatures that reach up to 450 degrees but it is possible that life exists in the atmosphere, to produce so much phosphine it is understood that they are organisms present that are expelling phosphine into the atmosphere.
