Astronomers have discovered samples of phosphine gas in the thick atmosphere of Venus, whose source is likely to be vital, according to a study published in the journal “NatureScientific, Monday.
Phosphine is a very toxic gas, produced on Earth by anaerobic microorganisms that do not require oxygen. And recently, research has been suggested to find phosphine in planetary atmospheres, as a sign that life might exist.
Venus is the second planet in the solar system in terms of its proximity to the sun, and it is earthy and has Earth-like characteristics.
And scientists found that this discovery will prompt them to search for life on this planet, which has a rich atmosphere.
Astronomy researchers question this hypothesis, and say that phosphine gas could result from unexplained atmospheric or geological processes on this planet, according to a report published by the newspaper The New York Times.
But what scientists agreed upon is that Venus still needs to study the possibilities of life in its atmosphere, and to search whether the phosphine gas in its atmosphere is of biological (biological) origin.
Some scientists consider that Venus is the twin of the Earth, as it has the same mass, and what they know about it is that, millions of years ago, it was distinguished by an atmosphere in which life could flourish as we know it.
The researchers infer the possibility of life on Venus, that the Earth was not suitable for life millions of years ago, but it has evolved in which an oxygen-rich environment that allows life on it.
A study prepared by American researchers from the Goddard Institute for Space Studies of the US Space Agency “NASA”, issued in September last year, revealed that Venus, millions of years ago, had environmental characteristics that help the formation of life in it.
At that time, the surface of Venus contained water resources, and the atmosphere prevailing in it was mostly temperate, and its general temperature was moderate and stable, allowing life to exist, according to the same study.
The study authors assumed, according to the data they gathered, that the temperatures on Venus ranged between 20 and 50 degrees, which is an average that allows living organisms to live and continue, especially since the water element was available for about “three billion years,” according to the study.
However, this situation changed radically, about 700 million years ago, when the temperature of the planet doubled on Venus, bringing its average today to about 460 degrees Celsius.
