The James Webb telescope once again found the signs of life on the planets of the planet K2-18B observing a similar phenomenon on it, but later it was rejected after a more detailed study. About this report Letters of Astronomical Physics magazine.
The planet K2-18B is located at 124 light years from the ground. As observed, its atmosphere contains dimethyl sulfide and dimethyldisulfide – on earth, these substances can only develop algae.
At the same time, the other properties of this planet say that life cannot exist on scientists it believes that the atmosphere on K2-18B has a very strong greenhouse effect, so the average temperature of its surface exceeds the boiling point.
In addition, in 2023, James Webb found the trace of Dimethyl Sulfide in the K2-18B atmosphere. Later, these studies were criticized by the scientific community – scientists believed that it could distinguish Dimethyl Sulfide from methane in this situation only when its concentration was 20 times higher than on Earth, this was doubt. However, new observations have confirmed the presence of dimethyl sulfide or dimethyldisulfide and with a probability of 99.7%.
There is everything we know, a guican planet (the planets have a liquid ocean that has a hydrogen -rich atmosphere) with an ocean in a full life, a script, which we have received at the largest level, the Astronomy Institute of Cambridge Madhusudkhan.
However, the scientist emphasized that some unknown scientific processes may not be found on K2-18B. They can explain the presence of substances found.
