An international team of astronomers has found tentative but highly compelling evidence.
Over the years, rovers and other spacecraft on Mars have detected methane in the atmosphere. Astronomers from Curtin University's node of the International Centre of Radio Astronomy Research (ICRAR) and CSIRO conducted the research using the Murchison Widefield Array (MWA) telescope, exploring hundreds of times broader and deeper than any previous search for extraterrestrial life. Update 10/1: The possibility of life on Venus may have been discovered back in 1978 without NASA even realizing it. "Most people are fascinated by the question: 'Are we alone in the universe? Phosphine is so toxic that it has been used as a chemical agent in warfare and by terrorist groups. “As crazy as it might sound, our most plausible explanation is life,” Clara Sousa-Silva, a molecular astrophysicist at MIT and one of the authors of the new study, told me. Despite the search being the deepest and broadest in Earth's history so far, Professor Tingay said it was essentially just a drop in the ocean. (CNN)When scientists find microbial life thriving in some of the most extreme environments on Earth, it gives them hope that they may be able to find life on other planets. Scientists want to know if ancient Mars once supported microbial life. Underwater volcanoes release lava at 2,200 degrees Fahrenheit that solidifies into basaltic rock as the hot rock reacts to the cold ocean depths. *This article originally stated that no spacecraft had orbited Venus since 1985; a Japanese spacecraft is currently orbiting the planet.
By Ashley Strickland, CNN.
If life indeed resides in Venus’s atmosphere, it might be the last remnant of a wrecked biosphere. Where is the search for extraterrestrial life up to?
AEST = Australian Eastern Standard Time which is 10 hours ahead of GMT (Greenwich Mean Time), 10 years ago, Australia sent a message into space. Some point out that, after more observations, the signature of phosphine could turn out to be the trademark of another molecule.
Curiosity has observed and drilled samples of rocks rich in clay from the lake bed. “This discovery is now putting Venus into the realm of a perhaps inhabited world,” says Martha Gilmore, a planetary geologist at Wesleyan University who has proposed a robotic mission to study Venus in depth. Sousa-Silva and the other researchers mimicked similar processes on Venus using computer simulations. September 15, 2020 / 6:46 AM / CBS News Traces of a rare molecule known as phosphine have been found in the hellish, heavily acidic atmosphere of Venus, astronomers announced Monday — … "It's a little bit like buying a lotto ticket — you never know, that next observation that you make could be the one.". 09/14/2020 11:12 am ET Updated Sep 14, 2020 Astronomers Spot Possible Signs Of Extraterrestrial Life In Venus's Clouds There may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet, scientists said.
But Venus’s atmosphere is so acidic, with clouds made of droplets of sulfuric acid, that any phosphine would be quickly zapped. But natural, boring interactions between rock and water can also produce the gas, and the spikes could be puffs of molecules, formed billions of years ago, rising through new cracks in the ground. Atria theorizes that the intense radiation the planet endures may create a “chemical disequilibrium” that organisms could provide energy for organisms that are still hiding beneath the surface. Ancient Earth crater may explain how.
"It's about the journey as much as anything else for me," he said.
Although there is a region in the Venusian atmosphere, between about 50 and 60 kilometres altitude, where the temperature and atmospheric pressure are Earth-like, there is still the sulphuric acid and near-total lack of water for any putative life to have to deal with. Home of the Daily and Sunday Express. Consider methane, another gas produced by tiny microbes on Earth.
If we find it next door, even better.”.
The best evidence for life beyond Earth has been found in the most surprising of places – the atmosphere of Venus. Scientists have detected phosphine on Venus. **This article originally stated that Sagan and Morowitz's paper came out in 1963; they published it in 1967.
Not only could the asteroid be the key to finding life, but it could also give a clearer indication on the panspermia theory.
The samples were taken far from hydrothermal vents to prevent contamination, in case the bacteria was carried from one of them to the rocks, and the rocks were sterilized when they were brought up. “I’m skeptical,” Sousa-Silva said.
