Comet 3I/ATLAS continues to make astonishing headlines, thanks to new findings from astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA). This new research reveals that 3I/ATLAS is packed with an unusually large amount of the organic molecule methanol—more than almost all known comets in our own solar system.

"Observing 3I/ATLAS is like taking a fingerprint from another solar system," shares Nathan Roth, lead author on this research, and a professor with American University. "The details reveal what it's made of, and it's bursting with methanol in a way we just don't usually see in comets in our own solar system."
