Possible Extraterrestrial Life Found In Venus’s Clouds, Suggest Astrophysicists

Scientists have identified two gases in Venus’s atmosphere that could potentially indicate signs of life on our neighboring planet.

Discovery at the Royal Astronomical Society’s Meeting

At the Royal Astronomical Society’s National Astronomy Meeting in England, astrophysicists revealed their discovery of phosphine gas and ammonia gas in Venus’s dense and hot atmosphere. These findings, based on preliminary data, suggest that these gases are not easily explained by natural atmospheric or geological processes typically found on Venus. Instead, they might serve as potential biosignatures, hinting at the presence of life forms yet unknown to us.

Details from Astrophysics Researcher Dave Clements

“Preliminary analysis of new observations with a new receiver on the James Clerk Maxwell Telescope (JCMT), taken as part of the JCMT-Venus project, has confirmed the presence of phosphine and are hinting at larger amounts closer to the clouds,” Dave Clements, an astrophysics researcher at Imperial College London, told Newsweek.

“At the same time, observations with the Green Bank Telescope (GBT) at longer radio wavelengths are hinting at the presence of ammonia in Venus’ atmosphere, as well.”

Extreme Conditions on Venus

In the vast reaches of our solar system, Venus stands out as a realm of extreme conditions and potential mystery. Its thick atmosphere, dominated by carbon dioxide at 96.5%, along with nitrogen, sulfur dioxide, water vapor, and carbon monoxide in trace amounts, forms a hostile environment unlike any other planet in our vicinity.

Considerations for Further Exploration

Recently, astrophysicists at the Royal Astronomical Society’s National Astronomy Meeting shared intriguing findings about Venus’s atmosphere. They detected phosphine gas and ammonia gas, two substances that defy conventional explanations linked to atmospheric or geological processes known on Venus. These gases are considered potential biosignatures—clues that hint at the presence of life forms, although the findings are still in the early stages and await peer-reviewed publication.

Implications and Future Research

The planet’s surface, under its thick blanket of gases, presents even more extreme conditions. With atmospheric pressure about 92 times greater than Earth’s at sea level, and an average surface temperature soaring to around 872 degrees Fahrenheit, Venus showcases the consequences of its intense greenhouse effect. This effect arises from its dense carbon dioxide atmosphere, which traps heat from the sun and creates an inferno-like environment on its rocky terrain.

On Earth, phosphine gas is primarily produced by bacteria thriving in environments with low oxygen levels, making it a recognized indicator of biological activity. This association has led scientists to view phosphine as a potential biomarker, suggesting the presence of life forms in ecosystems where such conditions prevail.

“They’re possible biosignatures since producing these compounds of phosphorous (for phosphine) and nitrogen (for ammonia) in the oxidizing atmosphere of Venus is very difficult for normal, known chemical processes. On Earth, these two gases are largely produced by life or human industry, and phosphine has been suggested as a biomarker for planets orbiting other stars,” Clements said.

However, there could be alternative explanations for the presence of these gases in Venus’s atmosphere.

“We’re not claiming to have detected life, but we do not know the chemical routes through which they might be produced—everything we’ve explored so far for phosphine at least (ammonia has yet to be looked at in detail) hasn’t been capable, but there may well be things we haven’t thought of yet,” Clements said.

Ongoing Analysis and Future Missions

Currently, the researchers will persist in analyzing their preliminary data and exploring the origins of these gases on Venus, a planet known for its extreme heat.

“We have a lot of data from JCMT-Venus to process and digest before we can put the re-detection of phosphine on a solid footing. Ditto ammonia,” Clements said.

“And we have more data coming from a range of observatories. Elsewhere, there are plans for new missions to Venus, some of which will be able to explore the presence of ammonia and phosphine and how they might be produced—chemically or biologically.

Community Excitement and Continued Investigation

Regardless of whether these gases ultimately signify signs of distant life, these discoveries have sparked enthusiasm within the astronomical community.

“These are very exciting findings, but it must be stressed that the results are only preliminary and more work is needed to learn more about the presence of these two potential biomarkers in Venus’s clouds,” Robert Massey, the deputy executive director at the Royal Astronomical Society who was not involved in the research, said in a statement.

“Nevertheless, it is fascinating to think that these detections could point to either possible signs of life or some unknown chemical processes. It will be interesting to see what further investigations unearth over the coming months and years.”
