A recently discovered comet is plunging toward a fateful encounter with the Sun, which will determine whether it puts on a spectacular showing during the daylight or if it completely disintegrates ...

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.

A newly discovered comet is rapidly brightening and could become visible from Earth — if it survives an extreme close ...

It ain't from around these parts of space.

“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.

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 ...

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 using ALMA have found large quantities of methanol in comet 3I/ATLAS, making it one of the most alcohol-rich ...

Comets often look like simple icy wanderers with dusty tails, but the latest JWST observations show that their activity can be far more chemically selective. In one of the clearest demonstrations yet, ...
