![The JWST observation of the ice absorption dips of CH4, CO2, H2O , CH3OH + NH+4 molecules and the the emission line [S I] of the protostars. Upper Left Panel: The CH4 absorption dip feature in the stacked 1-dimension JWST/MIRI-IFU spectrum of protostar IRAS 23385+6053. The purple area marked the equivalent width of the CH4 absorption dip. Upper Right Panel: The CO2 absorption dip feature in the stacked 1- dimension JWST/MIRI-IFU spectrum of protostar IRAS 16253-2429. The purple area marked the equivalent width of the CO2 absorption dip. Bottom Left Panel: The ice absorption dips of H2O and CH3OH + NH+ in the stacked 1-dimension JWST/MIRI-IFU spectrum of protostar IRAS 23385+6053. The cyan and deep sky-blue marked the EWs of the two dips. Bottom Right Panel: The [S I] emission line in the stacked 1-dimension JWST/MIRI-IFU spectrum of protostar IRAS 23385+6053. The red area marked the equivalent width of the [S I] emission line. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/05/The-Spatial-Distribution-of-CH4.png?resize=1200%2C720&ssl=1)
The origin and evolution of organic molecules represent a pivotal issue in the fields of astrobiology and astrochemistry, potentially shedding light on the origins of life.
