"These initial Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life. The tentative detection of dimethyl sulfide in 2023 was made using the James Webb Space Telescope's NIRISS (Near-Infrared Imager and Slitless Spectrograph) and NIRSpec (Near-Infrared Spectrograph) instruments. The observations have reached the 'three-sigma' level of statistical significance – meaning there is a 0.3% probability that they occurred by chance. To reach the accepted classification for scientific discovery, the observations would have to cross the five-sigma threshold, meaning there would be below a 0.00006% probability they occurred by chance." "We wrześniu 2023 roku kosmiczny teleskop Jamesa Weba wychwycił w ten sposób wibracje z odległej o 124 lata świetlne planety K2 18B. Analiza wykazała obecność siarczku dimetylu, specyficznego związku, który w naszych ziemskich warunkach jest produktem procesów biologicznych żyjącego w oceanach fitoplanktonu."
