The interstellar comet holds more alcohol than almost all known comets in the solar system.

New data indicates Comet 3I/ATLAS is second only to C/2016 R2 in terms of methanol levels ever recorded in a comet within our solar system.

Astronomers studying the rare interstellar visitor 3I/ATLAS have discovered that the comet is unusually rich in methanol, a type of alcohol, offering a unique chemical snapshot of how planets may form ...

Learn how ALMA observations revealed unusually high levels of methanol in interstellar comet 3I/ATLAS and what the molecule’s chemistry may reveal about how icy bodies form around other stars.

Scientists are scrambling to explain why interstellar visitor 3I/ATLAS is carrying life's chemical building blocks at concentrations never before seen, and it makes its final pass through our cosmic n ...

“Observing 3I/ATLAS is like taking a fingerprint from another solar system,” explained Nathan Roth, an astronomer at American ...

The newly discovered object dubbed the Great Comet of 2026 may become visible to the naked eye during its close solar pass in April.

How different can a comet be when it formed around another star? For 3I/ATLAS, the answer is already reshaping how astronomers think about small icy bodies that drift between stellar systems. Only two ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected unusually large amounts of methanol, a simple alcohol, in interstellar comet 3I/ATLAS—levels that exceed those ...

It ain't from around these parts of space.

Could Comet C/2026 A1 (MAPS) be the next "Great Comet"? Discovered in January, this sungrazing comet may be visible in broad daylight this April.

Interstellar comet 3I/ATLAS will soon reach its closest distance to Earth, so this may be our last, best chance to see this rare object before it heads back out into the universe, never to return. One ...
