K2-18b is an exoplanet which is located about 124 light years away from planet Earth in the Leo constellation. It is smaller than Neptune and has been a subject of intense study since its discovery. The recent findings by the James Webb Telescope have provided great insights about the planet's atmosphere and the probability of habitability. It gives hope to scientists who are deeply invested in the search of extraterrestrial life. K2-18B and its atmosphere Recently, JWST has recognized the presence of carbon dioxide (CO2), methane (CH4) and water vapor ( H2O). These are few of the major molecules which suggests chemical processes and potentially habitable conditions. The combination of these three molecules are involved in a variety of biological processes. Methane is majorly associated with biological processes on Earth, although it can be prepared under certain chemical conditions. This is a huge turning point in the search of extra terrestrial life as this combination has the ability to increase the chance of habitability. Scientists have been working on these researches to find the potential biological activity on the planet K2-18B. Detection of DiMethyl Sulphide (DMS) JWST has recently discovered the presence of Dimethyl sulphide.
