How the corona bailout fell apart 2020-09-16T04:00:00Z The claims of phosphine on Venus hinge on the interpretation of a single feature, a dip in a spectrum of the planet’s atmosphere that was attributed to the gas’s presence. Is There Life on Venus? These Missions Could Find It 2020-09-23T04:00:00Z On Monday, scientists announced the astonishing discovery of phosphine in the atmosphere of Venus. The Search for Life on Venus Could Start With This Private Company 2020-09-15T04:00:00Z Bridenstine cited new research from an international team of astronomers that revealed the discovery of a rare molecule, phosphine, in the clouds of Venus. NASA chief says Venus is 'one stop in our search for life' 2020-09-16T04:00:00Z Comparably, after three years of Venusian chemistry and geology research, the scientists were hard-pressed to find any explanation for how the phosphine ended up in Venus's atmosphere aside from the possibility of anaerobic life. Phosphine gas, seen on Venus, is also produced by bacteria on Earth — but we don't know exactly how 2020-09-17T04:00:00Z The detection of sufficient quantities of phosphine in Venus’s atmosphere would be an intriguing pointer to the possibility of life in the sulfuric-acid clouds of our sister planet, but many questions would remain. Opinion | Venus may hold the answers about life we’ve been looking for 2020-09-14T04:00:00Z Astronomers on Monday reported the detection of a chemical in the acidic Venusian clouds, phosphine, which may be a possible sign of life. Missions to Venus: Highlights From History, and When We May Go Back 2020-09-14T04:00:00Z The company began looking into the possibility of a mission to Venus last year, before it knew about the phosphine discovery. The Search for Life on Venus Could Start With This Private Company 2020-09-15T04:00:00Z The team spent a year recreating the Venusian environment in computer simulations to test different explanations for the phosphine’s source and abundance. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z But precisely how bacteria generate phosphine is still something of a mystery. Phosphine gas, seen on Venus, is also produced by bacteria on Earth — but we don't know exactly how 2020-09-17T04:00:00Z And if phosphine is produced by biology, where did that life originate? Opinion | Venus may hold the answers about life we’ve been looking for 2020-09-14T04:00:00Z But the astronomical observations confirmed the highly intriguing presence of the chemical phosphine near the top of the acidic clouds that blanket the planet. Scientists spot potential sign of life in Venus atmosphere 2020-09-14T04:00:00Z With yesterday’s phosphine announcement, Rocket Lab’s mission now has the exciting prospect of contributing to a major scientific discovery, and changing how researchers conduct planetary exploration.

Daily briefing: ‘Unexplained’ molecule on Venus hints at life 2020-09-13T04:00:00Z Even so, he said, the phosphine discovery is “intriguing.” Scientists spot potential sign of life in Venus atmosphere 2020-09-14T04:00:00Z The researchers did not discover actual life forms, but noted that on Earth phosphine is produced by bacteria thriving in oxygen-starved environments. Potential sign of alien life detected on inhospitable Venus 2020-09-14T04:00:00Z “We know that it is an extraordinary discovery,” said Clara Sousa-Silva, a molecular astrophysicist at Harvard University whose research has focused on phosphine, and another of the authors. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z Certainly phosphine is difficult to produce chemically without life, but not impossible. Cloud-based life? Scientists believe there may be alien microbes floating in Venus' atmosphere 2020-09-15T04:00:00Z We don't know if the phosphine gas recently observed by telescopes is coming from floating microbes or has a simple non-biological origin. Will private firms win the race to Venus? 2020-09-14T04:00:00Z To create a phosphine molecule, Sousa-Silva said, requires an unusual force or mechanism. Scientists spot potential sign of life in Venus atmosphere 2020-09-14T04:00:00Z On Earth, microorganisms in “anaerobic” environments - ecosystems that do not rely on oxygen - produce phosphine. Potential sign of alien life detected on inhospitable Venus 2020-09-14T04:00:00Z On such worlds, “as far as we can tell, only life can make phosphine,” Dr. Sousa-Silva said. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z "Venus—with an atmosphere in which hydrogen is extremely scarce—is a place where phosphine is a plausible biosignature," Lunine said. Cloud-based life? Scientists believe there may be alien microbes floating in Venus' atmosphere 2020-09-15T04:00:00Z A Rocket Lab entry probe when it falls through the atmosphere at Venus is not going to spend long in the key zone where phosphine has been detected – between 50km and 60km in altitude. Will private firms win the race to Venus? 2020-09-14T04:00:00Z That gas is phosphine - a molecule made up of one phosphorus atom and three hydrogen atoms. Is there life floating in the clouds of Venus? 2020-09-14T04:00:00Z Its surface and atmosphere are rich in oxygen compounds that would rapidly react with and destroy phosphine. Potential sign of alien life detected on inhospitable Venus 2020-09-14T04:00:00Z If there really was phosphine on Venus, she believed there could be no other obvious explanation than anaerobic life. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z Shostak emphasized that it is not the discovery of phosphine that is "controversial," but the interpretation of its source. Cloud-based life? Scientists believe there may be alien microbes floating in Venus' atmosphere 2020-09-15T04:00:00Z The Japanese space agency's Akatsuki orbiter is the one mission at the planet at present, and it was built long before the phosphine question came up – so it's not really best-suited to study the issue. Will private firms win the race to Venus? 2020-09-14T04:00:00Z On Earth, phosphine is associated with life, with microbes living in the guts of animals like penguins, or in oxygen-poor environments such as swamps. Is there life floating in the clouds of Venus? 2020-09-14T04:00:00Z “Something must be creating the phosphine on Venus as fast as it is being destroyed,” said study co-author Anita Richards, an astrophysicist associated with the University of Manchester in England. Potential sign of alien life detected on inhospitable Venus 2020-09-14T04:00:00Z Chemists compare phosphine to a pyramid — one atom of phosphorus topping a base of three hydrogen atoms. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z The absorption levels suggest phosphine is present at concentrations of up to 20 parts per billion at altitudes above 53 kilometers, Greaves says. ‘Curious and unexplained.’ Gas spotted in Venus’s atmosphere is also spewed by microbes on Earth 2020-09-14T04:00:00Z Prof Jane Greaves from Cardiff University led the team that detected phosphine in the atmosphere at Venus. Will private firms win the race to Venus? 2020-09-14T04:00:00Z Prof Greaves' team first identified phosphine at Venus using the James Clerk Maxwell Telescope in Hawaii, and then confirmed its presence using the Atacama Large Millimeter/submillimeter Array in Chile.

Scientists find gas linked to life in atmosphere of Venus 2020-09-14T04:00:00Z In that setting, Dr. Sousa-Silva said, life is not necessary to form phosphine. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z On Earth, a variety of microbes that thrive in low-oxygen environments produce phosphine. ‘Curious and unexplained.’ Gas spotted in Venus’s atmosphere is also spewed by microbes on Earth 2020-09-14T04:00:00Z The gas in question is a nasty one called phosphine, a toxic and explosive molecule with a lingering odor of garlic and dead fish. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z They searched for phosphine, which is three hydrogen atoms and a phosphorous atom. Astronomers see possible hints of life in Venus’s clouds 2020-09-14T04:00:00Z Other production routes are so extreme – the bellies of Jupiter and Saturn – that on rocky planets, phosphine is considered a marker for life. Scientists find gas linked to life in atmosphere of Venus 2020-09-14T04:00:00Z Volcanic activity and lightning on Venus would not be sufficient to add more of this constantly disappearing phosphine, according to the researchers’ models. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z But the particular cloud layer where the phosphine is present happens to be relatively balmy, with ample sunlight and Earth-like atmospheric pressure and temperature. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z But finding even a small amount of phosphine on Venus is enticing because of how the gas is made here on Earth. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z Filiberto said the levels of phosphine found might be explained away by volcanoes. Astronomers see possible hints of life in Venus’s clouds 2020-09-14T04:00:00Z Greaves first spotted the phosphine signal late one day in December 2018 as she was about to leave work. Scientists find gas linked to life in atmosphere of Venus 2020-09-14T04:00:00Z “I got intrigued by the idea of looking for phosphine, because phosphorus might be a bit of a sort of go-no-go for life,” Dr. Greaves said. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z “It’s a really puzzling discovery because phosphine doesn’t fit in our conception of what kinds of chemicals should be in Venus’s atmosphere,” says Michael Wong, an astrobiologist at the University of Washington. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z They modeled things like lightning strikes and meteors bombarding the planet’s surface to see if such phenomena could produce the amount of phosphine they’ve seen. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z My favorite of these rare gases is phosphine. When We Finally Find Aliens, They Might Smell Terrible 2019-11-19T05:00:00Z The observations point to trace levels of phosphine, about 20 molecules per billion, at least 30 miles high in the Venusian sky. Scientists find gas linked to life in atmosphere of Venus 2020-09-14T04:00:00Z Dr. Sousa-Silva was surprised when Dr. Greaves said that she had detected phosphine. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z While doing so, she noticed a line associated with phosphine. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z “At some point, you’re left with not being able to explain it. Except we do know of a strange way of making phosphine on terrestrial planets — and that is life.” Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z To us modern, oxygen-loving beings, phosphine is an extremely toxic and outrageously foul-smelling molecule. When We Finally Find Aliens, They Might Smell Terrible 2019-11-19T05:00:00Z To generate the amount of phosphine observed, Earth microbes would need to work at only 10% of their maximum productivity, the scientists say. Scientists find gas linked to life in atmosphere of Venus 2020-09-14T04:00:00Z This time, they found, all signs pointed to phosphine, and a lot of it, ranging from 5 to 20 parts per billion. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z In the pilot episode of the series Breaking Bad, the character Walter White prepares phosphine gas to knock out two assailants who are threatening him. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z Recently, Sousa-Silva and some of the researchers on this discovery presented phosphine as a possible biosignature because of its association with some Earth life. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z The anaerobic life in these places produces lots of phosphine. When We Finally Find Aliens, They Might Smell Terrible 2019-11-19T05:00:00Z But new research suggests that it's possible E.T. isn't producing any of these and is emitting a gas nearly as toxic to humans as carbon monoxide — phosphine. Extraterrestrials may spout out toxic gas as a sign of life, researchers suggest 2019-06-26T04:00:00Z But on smaller, rocky planets like Earth and Venus, the researchers say, there is not enough energy to produce copious amounts of phosphine in the same way. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z Phosphorus and hydrogen “hate each other,” says Clara Sousa-Silva, a molecular astrophysicist at the Massachusetts Institute of Technology and a co-author of a study reporting the phosphine finding. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z Plus, it takes a lot of energy to make phosphine, and life is a particularly energetic source. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z One day we might detect phosphine in one of these atmospheres. When We Finally Find Aliens, They Might Smell Terrible 2019-11-19T05:00:00Z "We consider not only the spectroscopic potential of phosphine, but also its thermodynamic false positives, biochemical viability, and atmospheric survival." Extraterrestrials may spout out toxic gas as a sign of life, researchers suggest 2019-06-26T04:00:00Z Here on Earth, phosphine is found in our intestines, in the feces of badgers and penguins, and in some deep sea worms, as well as other biological environments associated with anaerobic organisms. Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z The gas giants Jupiter and Saturn contain phosphine because they have hot interiors where it can be energetically favorable to produce the molecule.

Children aged 7 to 17 killed in Texas home by toxic chemical gas 2017-01-03T05:00:00Z Although it's poisonous to life on Earth, phosphine is present in the atmosphere, albeit a "trace component," the researchers added in the abstract. Extraterrestrials may spout out toxic gas as a sign of life, researchers suggest 2019-06-26T04:00:00Z While few doubt whether this phosphine is there, what kind of life in the clouds of Venus would it take to actually make the gas? Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z Venus’s runaway greenhouse atmosphere, by contrast, is full of oxygen-containing chemicals such as carbon dioxide that would normally soak up phosphine’s phosphorus. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z I think it’s a very intriguing discovery, but it definitely needs to be explored more.” no one is crying “aliens” just yet First, we have to be sure that the gas is, indeed, phosphine. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z Authorities later determined that phosphine gas was likely released when the father used a garden hose on Sunday to try to wash away the pesticide. The Latest: Police launch criminal probe into poisoning 2017-01-03T05:00:00Z "Furthermore, if detected on a temperate planet, phosphine is an extremely promising biosignature gas, as geochemical false positives for phosphine generation are extremely unlikely," the researchers added in the abstract. Extraterrestrials may spout out toxic gas as a sign of life, researchers suggest 2019-06-26T04:00:00Z In their own paper, he noted, the researchers wrote that “the detection of phosphine is not robust evidence for life, only for anomalous and unexplained chemistry.” Life on Venus? Astronomers See a Signal in Its Clouds 2020-09-14T04:00:00Z Of course, there might be additional pathways to making phosphine the team has not yet considered. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z Further observations of the Venusian atmosphere are needed to really confirm that phosphine is there. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z Red phosphorus can react with hydrogen to produce phosphine - but not with hot water. How much of the science in Breaking Bad is real? 2013-08-16T00:25:19Z The phosphine fumigants were scheduled for review in 2012 or 2013 but that was moved up quickly after the Utah deaths.

Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z If the phosphine detection is confirmed, then people will set to work figuring out where it’s coming from. Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z He later explains to Jesse that this reaction produced poisonous phosphine gas. How much of the science in Breaking Bad is real? 2013-08-16T00:25:19Z The new rules, which went into effect Wednesday, ban the use of phosphine fumigants near residences, nursing homes, school buildings, hospitals or day care centers. EPA tightens rules on pesticide linked to deaths 2010-04-08T22:27:00Z If it is to be stored it must be carefully purified from phosphine, which is apt to cause sudden decomposition. The New Gresham Encyclopedia. Vol. 1 Part 1 A to Amide Making higher-resolution maps of where the phosphine appears and seeing if it exhibits any kind of seasonal variation could also help tie it to biological processes. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z The phosphine may have been found in clouds with moderate temperatures, but the area is still a ghastly place for life to survive, even for the hardiest of microorganisms.

Discovery of noxious gas on Venus could be a sign of life 2020-09-14T04:00:00Z The pure phosphine does not take fire spontaneously. An Elementary Study of Chemistry Consequently, since phosphoric acid results from the phosphine in crude acetylene when the gas is passed through aqua regia, silica may be found on subsequently evaporating the latter. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power According to these investigators the combustion of the phosphine causes a deposit at the burner orifices of phosphoric acid, which is raised by the flame to a temperature higher than that of the burner. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power In order to rule out all nonliving explanations for the creation of phosphine, researchers will have to learn a great deal more about the planet itself, including its chemistry, geology and atmospheric physics, he adds. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z We still don’t know exactly which bacteria produce phosphine on Earth, but some laboratory studies suggest complex microbial communities spawn the substance.

Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power In the preparation of phosphine, why is coal gas passed into the flask? An Elementary Study of Chemistry The detection and estimation of phosphine are, however, analytical operations peculiar to acetylene among common illuminating gases, and they must therefore be referred to. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The gaseous phosphine is not actually spontaneously inflammable at temperatures below 100° C.; but it oxidises so rapidly in air, even when somewhat diluted, that the temperature may quickly rise to the point of inflammation. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The phosphine finding might play a similar role in getting planetary scientists to pay more attention to Venus. Venus Might Host Life, New Discovery Suggests 2020-09-14T04:00:00Z The weight so found multiplied by 0.278 gives the weight of phosphorus in the form of phosphine in the volume of gas passed through the absorbent liquid. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power But crude acetylene is also accompanied by a third impurity, viz., phosphoretted hydrogen or phosphine, which in unknown in coal-gas, and which is considerably more objectionable than either ammonia or sulphur. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The phosphine is said to combine with the arsenic to form an insoluble brownish compound. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The essential constituent of bleaching-powder from the present aspect is calcium hypochlorite, which readily oxidises sulphuretted hydrogen, and more particularly phosphine, converting them into sulphuric and phosphoric acids, while the acetylene is practically unattacked. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power This mercuric chloride is said to form an additive compound with the phosphine of the crude acetylene, which compound is decomposed by the ferric chloride, and the mercuric chloride recovered. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power It should be noted that ammonia and sulphuretted hydrogen have one property in common which sharply distinguishes them from the sulphur "compounds," and from all the phosphorus compounds, including phosphine. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power It must also be remembered that chemical processes which are perfectly suited to the extraction of sulphuretted hydrogen and phosphine are not necessarily adapted for the removal of the other phosphorus and sulphur compounds.
