It ain't from around these parts of space.

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.

The interstellar comet 3I/ATLAS is unusually rich in alcohol — a chemical clue that could reveal how planets and icy bodies form around other stars.

The interstellar comet 3I/ATLAS is leaving our solar system for good. Here's what to know about its journey and NASA's ...

Lead researcher Nathan Roth said the image shows the comet is “bursting with methanol in a way we just don’t usually see.” ...

Analysis of the tail of 3I/Atlas reveals that it contains an anomalous proportion of methanol, a class of alcohol used in fuels.

In late 2025 a mysterious comet flew between the orbits of Earth and Mars and reached a speed of more than 150,000 miles per ...

The interstellar comet 3I/ATLAS was confirmed in July 2025 as the third known object to visit our solar system from interstellar space. Despite conspiracy theories, scientists say 3I/ATLAS shows all ...

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.

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

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 ...

Comets are pristine remnants left over from the solar system's formation 4.6 billion years ago, rather than younger fragments created by collisions between larger bodies, a new study suggests. The ...
