Scientists Find Evidence of an ‘Ocean’ on Exoplanet K2-18 b, 120 Million Light-Years Away

Scientists have found evidence that an “ocean” may exist on the exoplanet “K2-18 b,” which is 120 million light-years from Earth. Scientists at NASA have announced that they have found possible evidence that There may be an “ocean” on the exoplanet known as “K2-18 b,” which is millions of light years away. K2-18 b is a giant planet 8.6 times larger than Earth in the constellation Leo. Which is 120 million light years away from Earth. This star has been studied in the past with Hubble and Kepler. But didn’t get enough details. And recently, data obtained from the James Webb Space Telescope (JWST) has made progress in the study. Strange again! “Elon Musk” reveals the name of his new child “Tao Techno Mechanicus” created by scientist “Map of Mars” prepares for settlement on the red planet. Scientists find “galaxy bubbles” thought to be fossils left over from the “Big Bang”. The exoplanet orbits the cold dwarf star K2-18 in the NASA area. called Its interior is likely to contain a large layer of high-pressure ice. similar to Neptune But it likely has a thinner hydrogen-rich atmosphere and surface ocean. Surveying the chemical composition of K2-18 b’s atmosphere, James Webb found “an abundance of methane and carbon dioxide.” and lack of ammonia Support the hypothesis that There may be a hydrogen-rich subatmospheric ocean in K2-18 b,” the astronomers wrote. This exoplanet It has the potential to be a star with a hydrogen-rich atmosphere and a surface covered by water or an ocean. Also known as Hycean (Hycean; Hydrogen + Ocean), NASA hints at even more incredible possibilities. That is the discovery of a molecule called “Dimetyl Sulfide” (Dimetyl Sulfide; DMS), which on Earth “It is produced only by living organisms,” NASA states. “Most of the DMS in Earth’s atmosphere is emitted by phytoplankton in the marine environment.” However, astronomer Nikku Madusudhan of K University mbridge One of the researchers who discovered this evidence said that the existence of DMS still needs to be further studied and confirmed. “Detailed survey by James Webb forthcoming. It should be possible to confirm whether there is a significant level of DMS in the atmosphere of K2-18 b,” Madusuthan said. This isn’t the first time NASA has found signs of water on another planet. Water vapor was previously discovered on the small exoplanet HAT-P-11b, which is about the size of Neptune in the constellation Cygnus. It is also 120 light years away, but scientists are still excited about the discovery. Even though they emphasize that This does not mean that planets will always be able to support life, as K2-18 b has proven to contain water even after this. But it is also possible that The planet’s oceans may be too hot to be habitable. Madusudhan said “Our findings highlight the importance of considering a wide range of living environments in the search for life on other planets…Traditionally, The search for life on exoplanets has focused primarily on smaller, rocky planets. But Hytian worlds, which are often larger, are more conducive to atmosphere observation.” Madusuthan credits the discovery to telescope James Webb. “This discovery is only possible. This is because of James Webb’s extended wavelength range and unprecedented sensitivity, which enables efficient detection of spectral features in just two exposures.” He adds, “In comparison, One James Webb observation is as accurate as eight Hubble observations.” Compiled from NASA / The Guardian.
