Traces of phosphine gas are found in Venus’s atmosphere, which can be attributed to organisms living on Earth, scientists said on Monday, renewed about conditions on our nearest planetary neighbor.
Used a team of experts Binoculars To observe the upper cloud deck of Venus, about 60 kilometers (45 mi) below the surface, in the Atacama Desert of Hawaii and Chile.
They detected traces of flammable gas phosphine on it Earth Often caused by breakdown of organic materials.
Writing in Nature AstronomyThe team insisted that the presence of phosphine did not prove the presence of life on Venus.
Although the clouds revolving about its brushing surface are highly acidic and therefore very quickly destroy phosphine, research has shown that something was building it up anew.
Researchers made several modeling calculations in a bid to explain the new phosphine production.
He concluded that his research provided evidence for “heterogeneous and unexplained chemistry” on Venus.
Lead author Jane Greaves of Cardiff University’s School of Physics and Astronomy told AFP that the presence of phosphine alone was not evidence of life on Earth’s Nextor neighbor.
“I don’t think we can say that, even though a planet was abundant in phosphorus, it could be something more important to life, some other element, or conditions could be very hot, very dry,” he said. said.
Greaves said this was the first time phosphine had been found on a rocky planet other than Earth.
Response to the study, Alan Duffy, A. Astronomer Swinburne University and lead scientist at The Royal Institution of Australia said that when it was tempted to believe that phosphine was produced by life-savers, “we have to reject all other non-biological means of producing it”.
He called the discovery “one of the most exciting signs of the possible presence of life beyond Earth that I have ever seen”.
Thomas Zurbuchen, Associate Administrator Of nasa The Science Mission Directorate, which called Monday’s research “tricky”, has conducted several fly-bys of Venus.
Venus, which rotates in the opposite direction of the Earth and where it is prolonged 243 times a day, is a subject of intense interest among astronomers.
It is so close and so shaped to our home planet that some experts believe that it serves as a warning of the dangers of runaway climate change.
Previous studies have shown that clues indicating Venus being an active volcano include signs of recent lava flows.
