A turning point
Scientists from Cambridge University discovered Symptoms of life outside the solar system. The astronors, using the data of space telescope, found the chemical marks of the James Webb for the first time, as well as CH4 and CO2 molecules containing carbon, as well as the chemical marks of Dimethyl sulfur (DMS) and/or Dimdildisuldisulfid (DMDs). On the earth, these substances are produced only by living organisms, for example by sea phytoplankton. The smell of sea is the smell of DMs and DMDs.
The K2-18B outer planet is 124 light years from the ground, 2.6 times more than land and 8.6 times larger. It is probably covered with ocean. Researchers write about themselves – astronomers from Cambridge University – scientific article “New DMS and DMDS data by JWST Miri in the K2-18B atmosphere (James Webb Space Telescope-Telescope James Webb, Middle Instrument-This Camera and a Spectrography on a Telescope)“:
“Our results offer new independent evidence for the probability of biosphere in K2-18B.
In addition to carbon-containing CH4 and CO2 molecules, the detection of NH3 and CO (ammonia and carbon monoxide) is consistent with previous estimates for the Gycian (ocean-covered planet) world and incompatible with mini-neptune or gas dwarf scenarios. Previous observations also showed the possible presence of molecules, but the evidence was weak. This is a new independent proof of the presence of DM and/or DMDs at the level of 2.9σ-3.2σ supplements that increase the probability of a biosphere on K2-18 B.
The secret K2-18B was discovered in 2015 by Kepler Telescope. The red dwarf revolves around the stars of the K2-18-Leo constellation. The temperature of the planet is close to the world and returns so fast that it takes only 33 days.
“Through this fast rotation, this planet can be observed for a week to verify the data about the existence of life. However, this should be done with the help of another telescope,” he said. Lomonosova Vladimir Surdin, the name of Moscow State University Physics Faculty Assistant Associate Professor Sternberg.
Ocean full of life
According to Surdin, a telescope that can do this is now being built in Chile. It will start working in just two years. Cambridge astronomers calculated that the concentration of DM and DMDs in the K2-18B atmosphere is very different from the concentration of the Earth, and that there are usually a part of a volume. In K2-18B, according to estimates, ten pieces higher in a million.
Therefore, you can imagine an ocean where a strong biosphere is hidden.
Madhusudkhan, “Early theoretical studies, DMS and DMDs such as high sulfur content in worlds with high levels of sulfur gas -based gas estimated that it is possible,” he said. “And now we observe it according to those predicted. Considering everything we know about this planet, a world with a high sulfur content and a life full of life is a scenario that is best corresponding to the data we have ” – said Press release Cambridge University.
However, scientists emphasize that they do not announce the discovery of real organisms, but rather the results of the possible biological organism – indicator of the biological process – and the results of their research should be carefully handled.
However, many media have already baptized this scientific work with a turning point in finding a breakthrough and a turning point in finding life in space.
Is there life in K2-18b?
There are a number of items called Biosignurs. These are chemical compounds that can occur in the atmosphere of the planet as a result of the life of living organisms. For example, the world atmosphere contains only oxygen, which is only biogenic substance. In other words, if there was no life on our planet, at least in the atmosphere would not have such a large amount of oxygen.
Oxygen is not the only substance that can show the existence of life. There are other bioignons such as methane and phosphine and carbon dioxide. These articles are either completely or mainly in the atmosphere of life, the Evolution of the Stars of the Stars of the Faculty of Sciences Institute of the Russian Sciences Academy Institute, explained to Dmitry Viba and Gazete.
“The article means the other two biosignrator – dimethyl sulfide and dimmetyl sulfide and dimmetilldisüldisulfid.
The K2-18B outer planet has been the subject of discussions on the detection of these molecules in the atmosphere. However, the first message was not completely convincing, then the studies that object to his reliability emerged.
“Now the authors of the study decided to use another device. The space telescope worked on James Webb, but this time it contained another equipment. In these data, they found previously reported molecular symptoms. Therefore, the researchers confirmed their previous results, but at a more reliable level. This is not a discovery, but only a more reliable confirmation of the available data. Until now, there is no question of life of life, The information received during the study does not contain sensational discoveries. The detection of certain substances does not indicate the existence of life on the planet, they may appear in the atmosphere for another reason, but it should be sought, Vib says Vibe.
It is important to state that this planet is different from Earth. It was suggested that he could be a representative of the planetary class that was very large and not in the solar system. On such planets, there may be different conditions of worldly different conditions that may affect the chemistry of the atmosphere and the possibility of the emergence and existence of life.
Another researcher, Professor of Astrophysics Department and Star Astronomy Professor of the State Astronomy Institute, PKSTERNBERG (unit of Moscow State University MV Lomonosov), Physics and Mathematics Sciences Doctor Konstantin Zveznov.
“The substances on this planet may not show the existence of life on an outer planet. That is, the presence of such substances in the atmosphere is only necessary, but is not a sufficient condition for the evidence of the presence of biocrhodes. And the scientists in his studies only write this: his data needs to be clarified. ”
In addition, the article was published at this address. magazine Letters of Astrophysics Magazine. If there was a breakthrough, the broadcast would be in nature. So this is a standard method to obtain additional funds to finance future studies.
However, there is no doubt that the substances found in Vladimir Surdin and K2-18b show the existence of organic life. True, he believes that scientist James Webb telescope is not the most reliable data source, so he must verify it.
