The following video shows the complete coverage of the scientists discovering a rare gas called phosphine in the Venus Atmosphere. According to them, it could be a possible sign of alien life (tiny microbes) living in Venus clouds. It is because the detected phosphine amount is relatively large in quantity. The discovery also raises questions about its source as it’s also produced by volcanic & lightning activity.
Scientific facts say that the production of phosphine is only possible because of biological processes that happen on Earth. In the case of Venus, there might be other non-biological sources that made the possibility of phosphine discovery. The team that made this discovery was lead by Professor Jane Greaves, Cardiff University.
Reactions of Public
Reacting to this discovery, Alan Duffy, Astronomer from Swinburne University & Lead Scientist of Royal Institute of Australia, said: “It’s an interesting fact that phosphine could be formed by lifeforms, regardless of there are other non-biological means of producing it. But this gave us signs of the possible presence of life beyond Earth.”
Thomas Zurbuchen, Associate Administrator, NASA Science Mission Directorate (conducted multiple fly-bys of Venus), called this research “intriguing“. For your knowledge, Venus rotates opposite to the direction of Earth, and a day lasts 243 times longer. Its size is similar to our planet and some experts say that it serves as a warning of the dangers of runaway climate change. In the previous researches, the possibilities of active volcanoes & lava flows were also mentioned.
Why this is so exciting?
When we talk about life signs in the solar system, the possibility of Venus having one is close to Zero. It’s a hellhole for any type of life form to exist because 96% of the Venus’ atmosphere is made up of CO2. Then there’s a runaway greenhouse effect, taking surface temperature over 400C (similar to a pizza oven).
And suddenly we hear that there’s a presence of phosphine gas in Venus’ clouds. What do you think scientists would say? Space probes that landed on the planet survived for a couple of minutes before breaking down. And yet, 50Km above we find the shirtsleeves conditions. How? So if there’s life on Venus, then it’s exactly there where we might expect to find it. We have to send a probe to specifically investigate the atmosphere of Venus.
