Could there be life in the atmosphere of Venus ? Image Credit: NASA
The discovery of phosphine suggests that Venus may not be quite as inhospitable to life as previously thought.
With surface temperatures exceeding 860 degrees and crushing atmospheric pressures that are more than 100 times those found on our own panet, the conditions on Venus are undeniably hellish.
But while the likelihood of finding signs of life on its surface remains low, scientists have long speculated that primitive life forms could potentially eke out an existence high up in the clouds.
It's an idea that has been around for decades - even Carl Sagan speculated about the possibility of life in the atmosphere of Venus back in 1967.
Now a new study published today in the journal Nature Astronomy has revealed the discovery of phosphine on Venus - something that could indicate the presence of life.
"[The discovery] suggests either some exotic chemical process occurs we haven't got or thought of on Earth - or maybe that some kind of very robust organism survived the runaway greenhouse effect, and evolved up to live in the clouds," said Cardiff University's Jane Greaves.
The discovery was made using the James Clerk Maxwell Telescope in Hawaii.
"When Jane sent me the spectrum I sat in front of my computer blinking for about half an hour," said telescope director Jessica Dempsey. "I didn't believe she'd actually found it."
"We aren't saying it's a 100 per cent robust detection of life, but what we can say is that we've opened it up to the possibility that it is that."
Yeah that's basically what I was thinking as well. I mean I don't have the scientific training in those fields to explain it as well as you and the article did, but I too find a chemical reaction more likely than some floating microbes. Still would be cool. Same with Jovian life. I still very much hold out for the romantic idea of floating, jellyfish-like life in the atmospheres of the gas giants.
Gravity is not the only force at work here (if it was then metal boats wouldn't float on water). Microbial life could easily float in the atmosphere of Venus. Creatures as large as spiders have been found in Earth's atmosphere up to 5km high.
What is life, other than a series of more complex chemical reactions? I have heard it said a long time before this article that the colonisation of Venus could be an option in the future in the upper atmosphere where the atmospheric pressure is comparable to Earths.  Not quite sure what the point would be, other than to prove we can. I do so hope we find that proof of life in my lifetime, it’s so tantalisingly close.  And I wished they would hurry up with the James Webb as well.
Well, it looks like NASA might be re-jigging its exploration plans to include more exploration of Venus: https://www.abc.net.au/news/2020-09-17/nasa-considering-venus-mission-after-gas-discovery/12672078
What the hell are you talking about. We are exploring the **** out of our solarsystem, and Im guessing its just a matter of years before we have that final exhibit A. There may be secrets and conspiracies, but covering up extraterrestrial life should we find it on Venus (or anywhere else) I just dont see it happening. What would be the point? Â
