Hydrocarbons play a key role in shaping the chemistry of the interstellar medium, but their enrichment and relation with carbonaceous grains and polycyclic aromatic hydrocarbons still lack clear observational constraints. García-Bernete et al. report on the Webb infrared observations of the local ultra-luminous infrared galaxy (ULIRG) IRAS 07251-0248, which revealed the extragalactic detection of small gas-phase hydrocarbons. Image credit: García-Bernete et al., doi: 10.1038/s41550-025-02750-0.
