Comet MAPS (C/2026 A1), a "Kreutz sungrazer,” will skim the sun in early April and may put on a brief, dramatic show low in ...

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.

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

A newly discovered comet is rapidly brightening and could become visible from Earth — if it survives an extreme close encounter with the sun on April 4.

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

Remember 3I/ATLAS? Yes, the interstellar comet that made plenty of headlines in 2025 is still romping through our solar ...

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.

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 ...

The comet 3I/ATLAS is well on its way back into deep space, but the famous cosmic visitor continues to fascinate astronomers. Since its discovery in July 2025, researchers have spent months observing ...

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, ...

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 ...
