Possible Extraterrestrial Life Detection: JWST data suggests potential signs of life on exoplanet K2-18b (124 light years away), specifically the detection of dimethyl sulphide (DMS), a gas primarily produced by living organisms on Earth.
Significance of DMS: The amount of DMS detected on K2-18b is far greater than Earth’s levels.
JWST’s Role: JWST, launched in December 2021, made these observations, highlighting its ability to analyze
most powerful space observatory, a collaboration between NASA, ESA, and CSA. It orbits the L2 Lagrange Point (1.5 million km beyond Earth).
Infrared Observation: JWST primarily observes in the infrared spectrum, enabling it to see through cosmic dust and view early galaxies, unlike the Hubble Telescope which observes in visible and ultraviolet light.
JWST’s Objectives: JWST studies the formation of stars, galaxies, and planetary systems, and it is analysing exoplanet atmospheres.
JWST Components: Key components include the Optical Telescope Element (OTE), Integrated Science Instrument Module (ISIM), Sunshield, and Spacecraft Bus.
