Recently the space scientists ( Astronomers ) have made a huge discovery. They have found the strongest evidence yet of life on distant planet known as K2-18b ( EPIC 201912552 b ). The researchers were able to find possible hints of molecules that on Earth are signs of living organisms. These findings on K2-18b comes from a team of researchers in University of Cambridge England led by Nikku Madhusudhan.
K2-18b was first discovered in 2015 and is more than 124 light years ( 700 trillion miles ) away from Earth. K2-18b is 2.6 times bigger than Earth and orbits a red dwarf star.
Discovery was made from the data provided by JWST ( James Webb Space Telescope ). JWST is so powerful that it can analyse the chemical composition of the planet's atmosphere from the light that passes through from the small red Sun it orbits. The Cambridge group has found that the atmosphere seems to contain the chemical signature of at least one of two molecules that are associated with life: Dimethyl Sulphide (DMS) and Dimethyl Disulphide (DMDS). On Earth, these gases are produced by marine phytoplankton and bacteria.
Prof Madhusudhan said that if we confirm that there is life on K2-18b, then it should basically confirm that life is very common in the universe ( other than planet earth ) .
