Parallel field to protostar IRAS23385

This image was taken by Webb’s Mid-InfraRed Instrument (MIRI) of a region parallel to the massive protostar known as IRAS23385. 

IRAS 2A and IRAS23385 (not visible in this image) were targets for a recent research effort by an international team of astronomers that used Webb to discover that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

With MIRI’s unprecedented spectral resolution and sensitivity, the JOYS+ (James Webb Observations of Young ProtoStars) programme individually identified organic molecules that have been confirmed to be present in interstellar ices. This includes the robust detection of acetaldehyde, ethanol, methyl formate, and likely acetic acid, in the solid phase.

[Image description: A region of a molecular cloud. The cloud is dense and bright close to the top of the image, like rolling clouds, and grows darker and more wispy towards the bottom and in the top corner. One bright star, and several dimmer stars, are visible as light spots among the clouds. The image is a single exposure which has been assigned an orange colour for visibility.]
