Interstellar comet 3I/ATLAS' new discovery finds - how 3I/ATLAS bursting with methanol could reveal secrets of planet formation beyond our solar system

3I/ATLAS comet new discovery: Interstellar comet 3I/ATLAS, observed by ALMA, revealed an unusually high methanol content compared to solar system comets. This unique chemical signature suggests it formed in a vastly different planetary system, offering insights into exoplanet formation. The comet's outgassing behavior also provided novel data on interstellar object composition.
