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

At roughly 250,000 kilometers per hour, comet 3I/ATLAS did not merely enter the inner solar system; it tore through it at a ...

The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 billion years the age of the universe.

“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.

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 ...

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 ...

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

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.

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.

The interstellar comet 3I/ATLAS was the third object ever discovered in our solar system that originated from another star system. Despite a viral conspiracy theory, NASA officials have repeatedly ...
