JAMES WEBB FINDS POSSIBLE BIOSIGNATURE

The James Webb Space Telescope has found a possible biosignature on an exoplanet. New research using NASA's James Webb Space Telescope on K2-18 b, an exoplanet 8.6 times more massive than Earth, has revealed the presence of carbon-containing molecules, including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, which has the potential to possess a hydrogen-rich atmosphere and a water-covered ocean surface. The first glimpse into the atmospheric properties of this habitable-zone exoplanet came from observations with NASA's Hubble Space Telescope, leading to further studies that have since changed our understanding of the system. K2-18 b orbits the cool dwarf star K2-18 in the habitable zone and is located 120 light-years from Earth in the constellation Leo. Exoplanets like K2-18 b, which have sizes between those of Earth and Neptune, are unlike anything else in our solar system. #astronomy #exoplanets #universe #cosmos #science #space #documentary This video discusses: exoplanet k2-18b, k2-18b, habitable exoplanet, exoplanet with life, biosignature on an exoplanet, exoplanet with suspected life, James Webb Space Telescope, James Webb, JWST, James Webb studies exoplanet, life beyond Earth, universe documentary.
