Scientists detect potential sign of extraterrestrial life on Venus

On Monday, scientists said they have detected a gas called phosphine in the acidic clouds of Venus that indicates microbes may inhabit Earth’s neighbor, raising questions of potential life beyond Earth.

British scientists have claimed that phosphine gas has been found in the clouds above the planet Venus. Which has increased the possibility of life here. Phosphine is a colorless gas that smells like garlic or rotten fish. This gas is excreted in the absence of oxygen by mycobacteria. This gas is also produced in small amounts due to the breakdown of carbonic substances.

Fascin detected by telescope Astronomer Jane Greaves of Wales Cardiff University and her colleagues monitored Venus with the help of the James Clerk Maxwell Telescope at the Mauna Kea Observatory in Hawaii and the Atacama Large Millimeter Ari Telescope in Chile. This led him to discover the spectral signature of phosphine. After which scientists have expressed the possibility that this gas is in a very large amount in the clouds of Venus.

More likely to be micro bacteria on Venus Scientists have said that this chemical process has increased the chances of micro bacteria on Venus. However, this planet is not fit for humans to live due to its temperature. The surface temperature of Venus is about 464 ° C. At the same time, the pressure is also 92 times higher than on Earth.

The temperature above the surface of Venus is equal to that of the Earth The altitude of 53 to 62 kilometers above Venus’s surface is about 50 degrees Celsius and the pressure here is also equal to the sea level of the Earth. The clouds here are also extremely acidic. Due to which the phosphine molecules will break down very quickly. Researchers have said that the discovery of phosphine here has increased the chances of life. Therefore, more work is needed to confirm this.

NASA preparing to send two missions The US space agency NASA is working on two plans for the planet Venus. Which will give more information about the atmosphere here. Both these schemes have been named as DAVINCI and ‘VERITAS’ by NASA. NASA has not said when these plans will be launched.

Unknown geological or chemical phenomena occurring on the surface of Venus Scientists said that the presence of phosphine suggests that unknown geological or chemical processes are occurring on the surface of Venus. Therefore, further research is needed to better detect the origin of gas in the planet’s atmosphere. He wrote in his paper that phosphine on Venus may have originated from unknown photochemistry or geochemistry, or it may also originate with biological production of phosphine on Earth.
