Scientists discover signs of possible life on another planet – but not foreigners – national

Astronomers claim that they have discovered the strongest signs of possible life on the planet 700 trillion miles from Earth.

the Scientists from Cambridge University The mid -infrared camera was used from James Web telescope for space (JWST) to monitor external planets K2-18BA planet is not found in our solar system, which is eight times the size of the Earth, revolves around 124 light years.

The planet was first discovered in 2017 by Canadian astronomers while looking at the Earth’s telescopes in Chile, According to the New York Times. “Planet of Hessian”, and this means that it is home to the abundance of a molecule for the employment of life, in the middle of a A new study published in Astronomical Physics Magazine messages.

Astronomers have discovered chemical gas fingerprints in the atmosphere of the strange planet, which is produced only through biological processes on Earth.

The two-gases are created diathyl (DMS) and Dimethyl Disulphide (DMDS)-Sharing K2-18B notes on Earth by living organisms, especially microbial life such as sea plant plankton, known as algae.

This indicates that the planet may be filled with microbial life.

“These are the first hints we see about a foreign world that may live in it,” Niko Madosodhan of the Institute of Astronomy at the University of Cambridge told a press conference on Tuesday. It is in the interest of anyone to claim prematurely, we have discovered life.

“This is a transformative moment in the search for life outside the solar system, as we have proven that it is possible to discover vital neglect in the planets that can be the same dye with the current facilities. We have entered the era of astronomical astronomical.”

Madhusun, the main author of Astronomical Physics Magazine messages The study noted that there are ongoing efforts to search for signs of life in our solar system, including environments that may be favorable to life in places such as Mars, Venus and various icy shrines.

Those looking to discover actual organisms do not announce the potential biological – an indication of a biological process – and they say that the results should be seen with caution.

The results of the University of Cambridge reached the level of “three columns” of statistical importance, which means that there is a possibility of 0.3 percent that they occurred by chance, according to the report. To reach the acceptable classification of the scientific discovery, the report stated that the notes will have to cross the “five threshold and voices”, which means that there will be “less than 0.000006 per cent possibility that occurred by chance.”

Other astronomers have urged cautiousness for new results so that this can be verified by other groups.

“Rich data from K2-18 B makes it a confusing world,” Christopher Glenn, the main scientist in the Space Science Department at the Southern West Research Institute in Texas, Reuters said. “This recent data is a valuable contribution to our understanding. However, we must be very careful to test the data as much as possible.

“Unless we see us as they waving us, it will not be a smoking rifle,” Glenn told the New York Times.

“This is nothing,” said Planet scientist at Johns Hopkins University Stephen Schmidt, the planetary scientist at Johns Hopkins University. “It is a hint. But we cannot conclude that it is habitable yet.”

Ryan McDonald told Michigan University New world The “new JWST notes do not provide convincing evidence that DMS or DMDS is in the atmosphere of K2-18B.”

“We have a boy wolf for K2-18B, where many trilogy discoveries have disappeared completely when they are subject to a closer audit. Any claim to life outside the ground must be verified strictly by other scientists, and unfortunately many previous previous claims for K2-18B have not stand up in front of this independent examination.”

He also urged Madhusudan to be careful, saying: “First, we need to repeat the notes two to three times to make sure that the sign that we see is strong and increase the importance of detection.” He wanted to make sure that the possibilities of statistical fibs are less than almost one in a million.

Second, we need more theoretical and experimental studies to make sure whether there is another vital mechanism (not involved in biological processes) to make DMS or DMDS in a planetary atmosphere like K2-18B.

previously Notes by jwstWhich was launched in 2021 and became working in 2022, methan and carbon dioxide were identified in the atmosphere of K2-18 B, the first time that carbon-based molecules have been discovered in the atmosphere of the external planets in the Al-Najma Al-Najmah area.

“The only scenario that currently explains all the data obtained so far from JWST, including previous and current notes, is one where K2-18 B is the world of Hycean teeming with life,” said Madosodhan. “However, we need to be open and continue to explore other scenarios.”

When asked about a potential smart life on K2-18B during the press conference, Madosodhan said, “We will not be able to answer this question at this stage. Assuming the foundation line is a simple microbial life.”

He and his team said that between 16 and 24 hours of additional observations with JWST can help them reach the level of five traces.

“The previous theoretical work has predicted that high levels of sulfur -based gases such as DMS and DMDS are possible in Hycean’s worlds,” said Madosodhan. “And now we have noticed that, in line with what has been predicted. Given everything we know about this planet, the world of Hycean with a skilled ocean is the scenario that fits our best data.”

“Our work is the starting point for all the investigations needed now to confirm and understand the effects of these exciting results,” The co -author Svvas Constantino saidAlso from the Cambridge Astronomy Institute.

This is not the first time that astronomers have claimed that they have discovered a strange life.

In September 2020, Astronomers said that they discovered a chemical in flower clouds It is likely to be produced only through organic life. Two telescopes have discovered the presence of phosphine in clouds on Venus, according to A study published in nature And another was presented to the magazine astronomy. Chemical not only comes from factories and microbes that live in oxygen -free environments on Earth, and there is no other natural process known to produce.

This means that a chemical should not be found in this model except for “the existence of life” or through some unprecedented chemistry, according to the authors of the study.

“I am just surprised,” said Jin Griffs, the author of the main study and professor at Cardiff University in the United Kingdom.

This discovery was not evidence of life, but it was a good progress that could help astronomers narrow the range on the type of foreigners that they should search for on Venus, according to Greaves.
