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

A century of solar observations from Kodaikanal Solar Observatory and modern satellite data reveal patterns in the Sun’s polar magnetic activity, aiding predictions of future solar cycles.

Flybys of Jupiter’s fiery moon Io, carried out by NASA’s Juno spacecraft, are helping to solve the enduring mystery of why the small moon is the most volcanically active body in our solar system.

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