The search for extraterrestrial life has long gone back and forth between scientific curiosity, public fascination and outright skepticism. Recently, scientists claimed the “strongest evidence” of life on a distant exoplanet – a world outside our solar system.Newton’s laws of motion and gravity, Wegener’s theory of plate tectonics, and human-made climate change all faced prolonged scrutiny before achieving consensus.In the case of the exoplanet, K2-18 b, scientists working with data from the James Webb Space Telescope (JWST) announced the detection of gases in the planet’s atmosphere – methane, carbon dioxide, and more importantly, two compounds called dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). As far as we know, on Earth, DMS/DMDS are produced exclusively by living organisms.Their presence, if accurately confirmed in abundance, would suggest microbial life. Do you believe in the existence of Aliens ?
