Guest Dempsey runs the James Clock, Maxwell telescoping Hawaii, and in a moment a- comment from Professor Paul Davis on that sensation. Also in the sideshow, how space research can stimulate interest incites how art consistent ecology and genius of Ferdinand Bauer. So back to Jessica with Fran, the first thing is we weren't expecting to find it our lead author Jane Grebes definitely thought she should go and check for this and even Jane, though didn't believe that we would actually get detection and so unlike here on Earth where we know these microbes can exist these clouds of Venus very, very different and Leo absolutely astonished to actually. Find. phosphene gas in these temperate clouds above the. Surface and we were surprised mostly because we don't think of temperate climate when we think of Venus. Venus is hellishly hot. Isn't it? Oh, it's terrific I mean it's on the surface to melt lead. But as you come up above the surface, you actually get into clouds which are actually temporary. So they're up to about thirty degrees Celsius. So they far cooler and so that I dot means that guess potentially this has been talked about as somewhere that could hop allies. So quite a long time, but I mean is a biomarker. This is something which we've been talking about of if we went and found these planets outside of our solar system, how could we tell us last maybe is there and we need to see what's in the atmospheres and phosphene is a very specific product of life you and. So. That's why we're so excited to see. This is certainly doesn't tell us absolutely we have found life. We are very, very clear on this because we need a lot more evidence before we go there but the hand allies him just Dempsey in Hawaii and she was surprised as you heard. PULL DAVIS WE YOU SURPRISED Well I'm never surprised these days I lived through. So many of these, we've discovered life stories that there's always another one coming and the question is, is this different from the previous times I think we've. been fixated by methane miles as a potential bio signature, and obviously we need to follow up on that but fussiness and ones to me. Tried even have it before these reports it has been found on Venus because it's not the sort of stuff you have lying around in your home. In fact, you wanted in your home it's a very poisonous. So as a bio signature, this was new to me, but the degree of phosphate in the abundance in the Benicia, atmosphere seems extraordinarily high compared to say the earth and that is obviously a problem in terms of, is it the product of life I remained cautious that needs to be a lot of follow I remain astounded because if you go back to the history of Venus Scientists worked on it, Carl Sagan. Famously, we've heard to some extent maybe on breakfast you heard his voice talking about the way in which calmed oxide built up and gave us this feeling about climate change in such like where you incredible heating of four twenty, four, fifty degrees. C.. And then David Chen from the anglo-australian telescope did the first x Ray examination, I think the surface looking through what the surface of maybe like and Hale is a good description they you know the hate, the acid life how well not on the surface of Venus it is Environment, but it's long been recognized that up in the clouds of Venus high up in the atmosphere where the temperature is cooler, that's a possible habitat for life. The problem is incredibly acidic and years ago people felt that microorganisms couldn't exist in such conditions. But now here on earth, we found a seato files as I called microbes that can tolerate conditions sick they would burn your skin on their poverty. Happy. Now it's not inconceivable the there could be some sort of life in the atmosphere Venus living in these highest conditions I'm producing the phosphene. How are we going to check what he really needs to some sort of mission to Venus to scoop up this stuff on your? Planned tool. Well,

Coming up next
