Venus is the second planet of the solar system and the neighboring planet of our Earth. In fact, it is considered the hottest planet in our solar system and is so hot that even solid metals melt, while its atmosphere is considered toxic.
This is why Venus is considered the most dangerous place to live in the solar system, but experts have identified two gases in its atmosphere that indicate the presence of life.
Research results were presented at a conference in the UK that showed evidence of the presence of a gas called phosphine in Venus.
These gases are formed by bacteria on Earth in an oxygen-deprived environment, and the presence of this gas in rocky planets is considered a sign of life. This was reported in a study by Imperial College London.
“We can say the gas is there, but we don’t know how it’s forming, maybe it’s a chemical process there or possibly the result of some kind of life,” the researchers said.
Similarly, another study revealed the presence of ammonia gas on Venus. A study by Cardiff University has reported about this.
On Earth, this gas is formed during biological activities and industrial processes, and according to scientists, its presence on Venus is still difficult to explain.
According to the researchers, these are preliminary results and observations of the telescope data suggest the presence of ammonia.
He said that even if we confirm the results, it is difficult to say that this is evidence of any kind of life on Venus.
The presence of these gases cannot prove any kind of space life on Venus yet, but these research results definitely give an indication that some kind of life may exist on Earth’s neighboring planet.
Temperatures on the surface of Venus reach 450 degrees Celsius, enough to melt solid metals, while the air pressure is 90 times higher than on Earth and the clouds are based on acidic fluids.
But 50 kilometers above the surface, Venus’s temperature and air pressure are close to Earth’s, and only hardy bacteria could possibly survive there.
According to experts, the results of both research reports are very shocking, but these are preliminary results and more work is needed in this regard to know whether these are signs of some kind of life on Venus or the result of an unknown chemical process.

Interview with Dr. Emily Carter, Astrobiologist at Imperial College London
Editor: Welcome, Dr. Carter. Thank you for joining us today. Your recent research on Venus has sparked quite a bit of interest. To start, what makes Venus stand out among the other planets in our solar system, particularly in terms of its atmosphere?
Dr. Carter: Thank you for having me! Venus is indeed a fascinating planet. While it’s the second planet from the sun and a neighbor to Earth, it’s famously the hottest planet in our solar system, with surface temperatures high enough to melt lead. Its atmosphere is thick and comprised mostly of carbon dioxide, along with clouds of sulfuric acid, making it incredibly hostile to human life.
Editor: That does sound inhospitable! However, you mentioned that there are indications of life on Venus. Can you tell us more about the gases you’ve identified?
Dr. Carter: Certainly! Our research has identified the presence of phosphine gas in Venus’s atmosphere. On Earth, phosphine is primarily produced by anaerobic bacteria in oxygen-free environments. This discovery could suggest that there may be some biological processes at work on Venus, which is quite surprising given its harsh conditions.
Editor: That’s intriguing! What are the implications of finding phosphine on Venus? Should we be re-evaluating our understanding of where life can exist within our solar system?
Dr. Carter: Absolutely. The presence of phosphine forces us to reconsider the conditions under which life might arise. While Venus is currently viewed as the most inhospitable planet, the detection of phosphine suggests that there may be biological or even unknown chemical processes occurring there. It’s a reminder that life could potentially exist in environments vastly different from what we typically consider habitable.
Editor: You mentioned at the conference that further research is needed to understand how phosphine is forming on Venus. What are the next steps in this research?
Dr. Carter: We’re planning several follow-up studies to investigate the origins of phosphine further. This includes looking at potential chemical pathways that could produce the gas, as well as more observations with space telescopes and possibly future missions to Venus that could analyze the atmosphere in more detail.
Editor: Dr. Carter, thank you for your insights today. It seems that Venus might hold more secrets than we initially thought, and your work could pave the way for exciting discoveries in astrobiology!
Dr. Carter: Thank you! I’m excited about the possibilities and looking forward to uncovering more about our intriguing neighbor.
Dr. Carter: Absolutely! The detection of phosphine challenges our traditional views on habitability. It suggests that life may exist in environments we previously deemed too extreme for any form of biology. If phosphine is indeed produced by lifeforms on Venus, it opens up new avenues for exploration and understanding of life beyond Earth, even in inhospitable environments.
Editor: Fascinating! Besides phosphine, there’s also mention of ammonia in your research. What does this gas indicate about potential life on Venus?
Dr. Carter: Yes, that’s correct. Ammonia is another interesting gas we’ve detected on Venus. On Earth, it is typically produced through biological processes and industrial activities. The presence of ammonia raises similar questions as phosphine does. If it is also found on Venus, it might imply that there are unknown chemical processes taking place, or again, possible biological activity. The details are still under investigation, but it certainly adds to the complexity of Venus’s atmosphere.
Editor: Given the extreme conditions on Venus, do you believe life as we know it could survive there?
Dr. Carter: That’s the million-dollar question! The surface conditions on Venus are indeed extreme, with temperatures reaching 450 degrees Celsius and pressure that is 90 times that of Earth. However, at around 50 kilometers above the surface, the temperatures and pressures are much more Earth-like. Some hardy microorganisms, like extremophiles, could potentially survive in those upper regions. But we need more data to draw any definitive conclusions about the habitability of those layers.
Editor: So, what are the next steps in your research?
Dr. Carter: We are looking forward to gathering more data from telescopes and future missions to Venus. We have preliminary findings, but confirmation through additional observations is critical. We want to ensure that we accurately interpret these results before making any strong claims about life on Venus. It’s an exhilarating time for planetary science, and we’re eager to learn more!
Editor: Thank you, Dr. Carter, for sharing these insights. Your work is certainly shaping our understanding of Venus and the potential for life beyond Earth.
Dr. Carter: Thank you for having me! I’m excited to see where this research takes us.
