The James Webb telescope was launched with the hope of new discoveries and to know the origin of our universe. This mission is on air, and the struggle to understand the universe is going ahead.

Humanity's biggest question, whether we are alone in this universe, has finally been answered in the atmosphere of some faraway planet because, according to scientists, the James Webb Space Telescope has discovered alien life on K2-18 B. For decades, we have been wondering if there is life elsewhere, and now, finally James Webb Space Telescope has brought the answer we were waiting for. This discovery has created a stir in the scientific world because the James Webb Space Telescope has discovered such alchemical elements in the atmosphere of exoplanet K28B, which are exactly like those produced by living beings on land. The real hero of this discovery is a molecule called diethyl sulfide or DMS. On our land, this compound is produced almost only by living beings, especially by microscopic living beings living in the sea. Phytoplankton are found near the surface of water. When the James Webb Space Telescope sensed DMS in the atmosphere of K28B, scientists were surprised because this is not a common chemical. It is possibly a sign of extraterrestrial life. And the matter did not end here. The telescope also detected dimethyl sulfide, or DMDS, and other carbon-containing molecules such as methane and carbon dioxide.

All these together create a picture of K2-18B that has surprised astrobiologists. The quantity of these possible biosignatures is not just like that of land, but it is thousands of times more. This suggests that there is possibly some biological activity going on there, which is many times greater than in our land's oceans. The results are also so interesting because DMS has a special property. Unlike methane or oxygen, DMS is made up of only biological acids. DMS is formed on land when marine microbes break down a chemical called DMSP as part of their metabolic process. The technical breakthrough that made this discovery possible is a truly remarkable achievement.

The James Webb Space Telescope is a great example of human engineering and ingenuity. This is technology that was only science fiction a few decades ago. Its near-infrared spectrograph and mid-infrared instrument allowed scientists to study the light passing through the atmosphere of the K2-18B planet. When this light passed through the atmosphere of the planet, some wavelengths got scattered, which created an alchemical fingerprint that scientists read. When this data was first presented, researchers checked these results several times to identify DMS. The spectral lines were absolutely correct, but they were so unusual that it was necessary to be cautious while looking at them. In science, it is said that unusual claims require unusual evidence; that is why the research team believed it in every way before saying anything with certainty. Let us now try to know what the statistical significance of this discovery is. These discoveries have reached the level which is called the sigma level, that is, there is only a 3% chance that these signals are just a coincidence or noise. The fact of achieving three sigma levels is also really amazing, but the highest limit in physics and astronomy is five sigma, that is, only one chance of error in 3.5 million. Scientists usually consider something a reliable discovery only when this limit is met, although some scientists although there are still have doubts. This discovery is considered particularly strong because it is based on not just one but several different witnesses.

Not only were DMS traces found, but some other biology-related molecules were also detected. Then there is also the fact that K2-18B is in the habitable zone of its star, where water may be present in the form of water. This star has been classified as a high CN planet. High CN planets are those whose atmosphere is rich in hydrogen, and they have deep oceans. Some scientists consider such an environment to be the best incubator for life. Even those scientists who are usually very cautious and who have always looked at the claims of extra-terrestrial life with a critical eye are also agreeing that this is the strongest discovery so far. There may be evidence that life exists somewhere other than the Earth. Although they are also saying that more observations are needed, after this discovery, a new enthusiasm is being seen in the conferences and meetings of scientists. Throughout our human history, we have been looking at the stars and wondering if someone is watching us, too. These biosignatures do not prove this with complete certainty, but have brought us closer to this answer than we have ever been before. This request shows that perhaps the universe is not as deserted as we think. Perhaps the miracle of life has happened at least in two places in our cosmic neighborhood. And what is even more interesting is that K28B is not a rare cosmic ... But if life exists, it could exist in countless other places, too, such as the biospheres scattered across the Milky Way that have not yet been discovered by us.

The clues to life on K28B are waiting to be discovered. Finding clues to life on K28B is more than just the presence of chemical evidence. This forces us to try to find the possibility of life on exoplanets in an environment where everything is completely different from Earth.

K28B is a high world, that is, a planet whose atmosphere is rich in hydrogen, and beneath it, the entire planet may be filled with water. Such an environment is not found anywhere on Earth, but still, it can be very suitable for some special kind of life. If the biosignatures discovered through JWS ST are indeed due to living beings, then these living beings have learned to live in an environment that is very difficult for us to understand. The mass of K28B is about 89 times more than that of the Earth, and its radius is also 26 times larger than that of the Earth; that is, the force of gravity and gravity on it is very strong. The pressure is so high that most of the land animals cannot survive there, but on land, we have seen that life can survive even in extremely difficult conditions. According to scientists, the living beings present on this platform are probably like the extremophiles present on land. These are such microbes that can survive even in those places where life cannot be imagined. Some extremophiles are alive even in those parts of the land where water is boiling and its level is more than 250 degrees Fahrenheit, while some thrive in very acidic environments, and some tolerate so much radiation that no human can tolerate it.

The possible life on K2-18B may even put the extremophiles found on our land to shame because the creatures there must have flourished in an environment that is full of high pressure and hydrogen. Where the body is dominated by hydrogen and has no parallel on land, the metabolic processes that support life may be completely different from those on land. Most life on land relies on photosynthesis or chemosynthesis, i.e., living things on land use sunlight or chemical energy to make complex organic compounds. But life in the depths of the oceans on K28B may use completely different sources of twana. Some scientists think that the organisms there may be so advanced that they combine the abundant hydrogen in their atmosphere with dissolved carbon dioxide to make twana and discard DMS as a waste product. The most surprising thing is how much of all this must be happening here. But your question would be whether K28B, complex and multicellular life, can also exist. Let us find out. Although most scientists believe that the first life to be discovered outside the Earth would be microbial, the powerful biosphere of K2-18B can support even more complex creatures.

The multicellular organisms present on Earth took billions of years to reach their present form through the process of evolution. But in an environment like K2-18B, the process of evolution can be different due to different pressures and availability. Now imagine creatures that have gas bladders to float at different depths, creatures that get hydrogen from hydrogen-rich water, or creatures that come together to form large floating colonies. K2-18B may be a planet where life is limited only to habitable places. It is not limited but spreads all over the vast oceans. If you could dive below the clouds of K28B and see its unseen ocean, what do you think would be there? Will there be single-celled organisms or multicelled life? There may be organisms like fish in the oceans of K2-18B that are swimming in the depths of the ocean. What do you think? Do give your opinion in the comment section. So this was today's news.
