A comet swept through the solar system carrying a strange chemical recipe — one that has astronomers taking a closer look at what kinds of worlds might form around distant stars ...

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.

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

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

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 ...

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

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 ...

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 ...

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.

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 ...
