If there is some biological process producing phosphine on Venus, it may be a form of “life” very different from what we know on Earth. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes – floating free of the scorching surface, but still needing to tolerate very high acidity. On Earth, this gas is only made industrially, or by microbes that thrive in oxygen-free environments. On Earth, phosphine is only made industrially, or by microbes that thrive in oxygen-free environments. But there hasn’t been, again, there hasn’t been a sort of willpower to just actually build the probe or Lander itself and send it out to Venus. There’s so much of it in the clouds of Venus that it’s more likely from another source. Keep in mind that all of this is … Searches for life beyond Earth have often skipped over Venus, because its surface temperature is around 500℃ and the atmospheric pressure is … They could be living on Venus, producing this phosphine gas. Venus is a bit closer to the Sun so it is a bit warmer so there is slightly more water in the atmosphere than in Earth's atmosphere without oxygen there is no ozone layer; without an ozone layer, there is no protection for the water from solar ultraviolet (UV) radiation. Earth and Venus share many physical characteristics. Atmosphere is not one of them. How it got there is another question. And so there is a chance that we have detected some kind of living organism in the clouds of Venus." The phosphine is there. It’s just a matter of going,” Gilmore says. There is no free oxygen in the atmosphere of Venus, but a vast amount exists bound as carbon dioxide in the dense atmosphere of the planet. There's a chance alien life could live in the clouds above Venus, our second closest neighbour in the solar system. Just because something doesn’t require oxygen doesn’t mean it’s completely lifeless. Millions of tons of it. Rose McGowan calls Alyssa Milano a 'fraud' Student loan pause ordered by Trump is confirmed A false-color image of Venus as captured by the Ultraviolet Imager aboard Japan's Venus … Is There Life on Venus? An international team of astronomers have discovered a rare molecule – phosphine – in the clouds of Venus that could indicate the presence of life. There have been hints of life on Mars for decades that have been undermined by further study, and the same is likely true for Venus. “On Earth, there are only a few localities with hyperacidity and none as extreme as on Venus, so there would not be much motivation for Earth life to evolve such adaptations,” Schulze-Makuch says. Fighter wins biggest UFC upset since Rousey-Holm. - Is There Life on Venus? Is there life on Venus? “We have the technology right now to go into the atmosphere of Venus. Well into the space age astronomers believed that the planet had a climate similar to the tropical regions of Earth. Although there are microbes living in extreme places on Earth — such as geothermal pools — they live in environments that only have 5 per cent acid. image copyright DETLEV VAN RAVENSWAAY/SPL image caption Artwork: Venus … But wait you say, we all know Mars atmosphere has almost no Oxygen at all! In a 1967 letter to Nature he noted that parts of atmosphere of Venus might be habitable. Loads of it. So, if there really is life on Venus, this is exactly where we might expect to find it. Something deadly might be wafting through the clouds shrouding Venus—a smelly, flammable gas called phosphine that annihilates life-forms reliant on oxygen for survival. There’s been a lot of interest in the hot planet next door lately. Scientists Say Maybe Using telescopes, scientists measure signs of phosphine gas in the atmosphere of inhospitable planet—a possible sign of biological life Since Venus is oxygen rich..the phosphine molecule, with its 3 attached hydrogen molecules is a … Is There Life on Venus? The answer is possibly, ... is a gas only made industrially on Earth or by microbes that thrive in oxygen-free environments such as swamps or in the guts of animals like penguins. Keep Reading The Discovery of Black Holes: From Theory to Actuality The truth about Venus came as something of a shock. It can be done.” Mars. Is there life on Venus? While the same gas has been found in the atmospheres of Jupiter and Saturn, it’s understood that its creation there relies on chemical processes that aren’t possible on Earth or Venus. There — around 50km above the surface — temperatures and ... bursting into flame upon contact with oxygen. Twenty-five or so years later, astronomers figured out, thanks to the Cassini spacecraft , that a neighboring moon, Enceladus, spews water vapor into space that makes its way over to Titan and reacts with other molecules there to form oxygen. Venus has clouds 50 to 70 km above surface containing H 2 SO 4 (sulfuric acid). On Earth, this gas is only made industrially, or by microbes that thrive in oxygen-free environments. We know the surface of Venus is uninhabitable—clocking temps in the 470 degree Celsius range—but the discovery could indicate that some form of life exists in the clouds 50 to 60 kilometres above it. While Venus has been ignored because of its seemingly inhospitable conditions, researchers have what may be chemical proof of life. The majority of the planetary oxygen is bound as carbon dioxide and sulfur dioxide in the atmosphere, and as oxides on the surface. September 22, 2020 Staff Reporter Community News, Science & Technology 0. Here on Earth, it is naturally produced mainly by certain microorganisms in the absence of oxygen. It probably had an ocean for billions of years, and it’s right there. Published by Sinead Mackle on September 14, 2020 September 14, 2020. But that is one of sort of the exciting things about this new study, is that it raises more hopes in the possibility that we could build those sorts of things now, and that we have an actual sort of target for studying Venus in closer depth. Venus has been getting a lot of attention from the scientific community for a new report that hints at the potential of life on the cloudy planet. Also, if you count the oceans on Earth, Venus has a lot less water than Earth. Phosphine is a smelly flammable gas that harms life forms that rely on oxygen. There are a ton of factors to dig through here, but it’s definitely a very interesting story and could lead to some pretty remarkable new discoveries in the world of science. Notably, Venus has not been a significant part of the search for life because of its extreme temperatures, atmospheric composition and other factors. Dr Dave Clements So the researchers did the math on how much phosphine could be produced by: sunlight Where is this overly oxgenated planet you ask? Venus is often called Earth’s twin, and this gives us a huge reason to go and explore Venus. By the time the news excitement dies down, there is likely to be a dozen hypothetical processes proposed that could explain the strange presence of phosphine on Venus. If there was life on Venus, how would these aliens act? My best guess is that there is terraforming going on. Arik Kershenbaum: The model proposed by the scientists in this project suggests that these would be extremely simple, single celled creatures, similar to bacteria, each one floating in a single rain drop of sulphuric acid. Is There Someone Out There? There was oxygen in the atmosphere, and its existence couldn’t be explained through any of the regular methods. This discovery on Venus is similar – either there is a new part of Venus we have not understood, or it is from a biological process. These are organisms that don’t require oxygen to survive. Venus’s atmosphere is made of 96% carbon dioxide, and even though there are some H 2 O molecules around as well, there is no life and liquid water to absorb the CO 2 and create oxygen.
