We are faced with a possibility that is so big that there are organisms that live in the sky of the planet Venus.
A number of astronomers still continue to explore the possibility that once they detect gas in the atmosphere of Venus.
The Gas was later known as the gas phosphine, a molecule made of an atom of phosphorus and three hydrogen atoms.
On earth, the gas phosphine associated with life. This Gas is found in microbes in the gut penguins or the environment are minimal oxygen such as
On earth, phosphine gas is associated with life. This gas is found in microbes in penguins’ guts or in oxygen-poor environments such as swamps.
Actually we can create phosphine gas. But no factory can produce it on Venus. And of course, there are no penguins on the planet.
So why is phosphine gas in the atmosphere of Venus or about 50 kilometers above the planet’s surface?
Professor Jane Greaves of Cardiff University and a number of her colleagues have published their research on Venus’ phosphine gas in the journal Nature Astronomy.
They are also investigating how the molecule could have arisen naturally, without biological processes.
However, in the BBC Sky At Night program, Greaves and his colleagues admitted that they were in a state of confusion.
Given all we know about Venus, no one has yet been able to explain how the abiotic components could have formed the planet’s phosphine. That is, the source of life is worth considering.
“Throughout my career, I’ve always been interested in looking for life elsewhere in the universe. So now I’m surprised that life might actually be there,” Greaves said.
“But we really encourage others to share what we might have missed. Our research and data are openly accessible. That’s how science works.”
What is actually detected in the sky of Venus?
Greaves and his team first identified phosphine gas on Venus using the James Clerk Maxwell Telescope in Hawaii.
They then confirmed the presence of the gas using the Atacama Large submillimeter telescope in Chile.
Phosphine has a special ‘absorption line’ that this radio telescope sees at a wavelength of about 1 millimeter. The gas is observed in the middle latitudes of Venus at an altitude of about 50-60 kilometers.
The number is arguably small, only 10-20 parts in every one billion atmosphere molecules. But in the general context, it is a very large number.
But why should we be skeptical?
The clouds on Venus are thick and mostly ((75-95%) sulfuric acid, which is a catastrophe for the cellular structures that make up organisms on Earth.
Doctor William Bains, a scientist affiliated with the Massachusetts Institute of Technology (MIT) in the United States, is a biochemist on the team headed by Professor Jane Greaves.
Bains studied the different combinations of compounds thought to exist on Venus. He examined whether volcanoes, lightning, and even meteorites could play a role in the creation of PH3.
All of the chemical reactions he investigated, Bains said, were 10,000 times too weak to produce the amount of phosphine they observed.
According to Bains, to survive sulfuric acid, microbes in Venus’ air must use various chemical molecules or develop some kind of shield.
“In principle, life that prefers water could hide in a kind of protective shell inside a drop of sulfuric acid,” Bains said.
“We’re talking about bacteria protecting themselves with something tougher than a Teflon coating and actually sealing themselves off.
“But how do the bacteria eat? How do they exchange gases? It’s really a paradox,” he said.
