Astronomers claim that the strongest signs of possible life have been discovered on a planet 700 trillion miles away from Earth.
Scientists at Cambridge University Used the middle infrared camera from this James Webspace telescope (JWST) to observe the Acupalnate K2-18bA planet that is not in our solar system and is eight times the size of the Earth, with a stars rotating at a distance of 124 light years.
The planet was first discovered by Canadian astronomers in Chile in Chile by reviewing ground -based binoculars, According to the New York Times. “Hyssen Planet” means that it is the home of the abundance of molecules decorating life, in the center of a I published a new research The letters of the astronomical journal.
Astronomers detected chemical fingerprints of gases in the environment of the planet that are manufactured only by biological processes on Earth.
Two gases-dimithail sulfide (DMS) and dementiael disscalephide (DMDS)-K2-18B are born on the ground through living organisms on earth, mainly as microbial life such as marine phytoplanicton, commonly known as tabor.
Researchers said it shows that the planet can be linked to microbial life.
“These are the first indicators that we are seeing about a stranger world that is potentially settled,” said Nicco Madhushanodhan of the University of Cambridge's Institute of Astronomy. “Premature claiming is not in the interest of anyone that we have found life.
“This system is a moment of a change in the search for a life -long life, where we have shown that it is possible to detect biofuchers in potentially living planets with existing facilities. We have entered the era of observer astronomers.”
The main author of Madhsan, The letters of the astronomical journal Studies, it has been noted that efforts are being made to find symbols of life in our solar system, including environments that can be conducive to life in places like Mars, Venice and various icy moons.
Researchers are not announcing the discovery of real organisms, but a potential bio -scorch – an indicator of the biological process – and say that these results should be viewed cautiously.

According to the report, the results of the University of Cambridge have reached the “three Sigma” level of the importance of statistics, which is likely to be 0.3 % of it. To reach the accepted ranking for scientific discovery, the report states that observations will have to cross the “five Sigma limit”, which means that there is less than 0.000006 % likely that they will be accidentally.
Other astronomers have called for careful caution on new results unless they are confirmed by other groups.
Christopher Glenn, Principal of the Space Science Division of the Southwest Research Institute in Texas, “K2-18 B-rich figures make it a contradictory world.” Tell Reuters. “These latest data are a valuable contribution to our understanding. Still, we must be very careful about examining the data as much as possible. I'm looking forward to seeing additional, free work on the data analysis starting next week.”
“Unless we see ET waving on us, it doesn't become a smoking gun,” Glenn told the New York Times.
“That's nothing.” “This is a signal. But we cannot conclude that it is still a capable housing.”
Ryan McDonald said at Michigan University The new scientist “The new JWST observations do not give convincing evidence that there are DMS or DMDs in the 2-18b environment.”
“We have a Haird of Woolf situation with a boy for K2-18B, where several previous three Sigma finds have been detected when it is completely exhausted when it is close to check. No other claims of life outside the earth have to be strictly checked by other scientists, and they have to be very free.
Madhusudan also carefully said, “First we need to repeat the observations two to three times to ensure that the signal we are seeing is strong and the importance of detection is to increase.” He wanted to make sure that the problems of the data flook are almost below one in a million.
“Second, we need more theoretical and experimental studies to ensure whether there is any other abdominal mechanism (not included in a biological process) to create a DMS or DMD in the planetary environment like K2-18B. Although previous studies have strong bio-bio-bio-bio.”
Ago JWST's observationsWhich was launched in 2021 and became operational in 2022, identified methane and carbon dioxide in the K2-18b environment, for the first time when carbon-based molecules were discovered in an explanatic atmosphere in the stars' housing zone.
“The only scenario that explains all the figures received from JWST, including past and present observations, is currently where the 2-18 B is a Hyesen world that meets life,” “However, we need to remain open and search for other scenario.”
When asked about a potential intelligent life at K2-18B during the press conference, Madhushadhan said, “We will not be able to answer this question at this stage. Baseline is a simple microbial life.”
He said he and his team estimates that more observations with JWST can help them reach the five -level level between 16 and 24 hours.
“Earlier, ideological work predicted that high levels of sulfur -based gases in Hyssen worlds were possible, DMS and DMDS,” said Madhusodhan. “And now we have witnessed it, which was predicted. Whatever we know about this planet, a Hyesen world with a sea that is mixing with life is the scenario that fits the data we have.”
“Our job is the starting point for all the investigations that are now needed to confirm and understand the implications of these exciting results,” Co -author Sawas Kantino saidAlso from the Institute of Cambridge, astronomy.
This is not the first time astronomers have claimed to have detected alien life.
In September 2020, Astronomers said they found a chemical in Venice clouds The possibility of this can be produced only through organic life. According to one, two telescopes detected the presence of phosphine in the clouds above Venice Appeared in the study Nature And presented in another journal Astro Biology. This chemical only comes from factories and germs living in oxygen -free environment on the ground, and there is no other known natural process to manufacture it.
This means that there is no way to present chemicals in this form, except that “the presence of life” has never been seen before.
“I was just stunned,” said Jean -Grews, author of the central study at Cardiff University in the UK.
This discovery was not a proof of life, but it was a good edge that could help experts reduce astronomers on what kind of foreigners should look for Venice, according to Grace.
