- Legenda: A graph shows the observed transmission spectrum of the habitable zone exoplanet K2-18 b using the James Webb Space Telescope MIRI spectrograph instrument. The vertical shows the fraction of star light absorbed in the planet's atmosphere due to molecules in its atmosphere. The data are shown in the yellow circles with the 1-sigma uncertainties. The curves show the model fits to the data, with the black curve showing the median fit and the cyan curves outlining the 1-sigma intervals of the model fits. The absorption features attributed to dimethyl sulphide and dimethyl disulphide are indicated by the horizontal lines and text. The image behind the graph is an illustration of a hycean planet orbiting a red dwarf star. This image was obtained by Reuters on April 16, 2025. A. Smith, N.
