Interstellar Comet 3I/Atlas Has Another Surprise: It’s Full of Alcohol

3I/Atlas coma was heavily enriched in methanol, aLMA observations of the comet's coma.

3I/Atlas methanol abundance reached up to four times the typical amount found in solar system comets comparison with typical solar system comets reported in the study.

3I/Atlas is the second most methanol-rich comet measured, after C/2016 R2 ranking stated in the paper available at arXiv.

3I/Atlas coma composition contained high abundances of carbon dioxide, iron, and nitrogen other compounds detected in parallel investigations.

Formation hypothesis may have formed in an environment that was colder, more irradiated, or chemically distinct from regions where solar system comets formed authors' interpretation in the paper.
