A reevaluation of the Moon’s crater record suggests that the rocks at the Apollo 14 landing site are 200 million years older than previously thought, which has implications for the surface ages of other solar system bodies.

A survey of hundreds of thousands of asymptotic giant branch stars in our galactic neighbor, Andromeda, suggests that 0.9–35.5% of the galaxy’s dust is generated by these evolved stars.

Some stars near the galactic center and in the plane of the Milky Way show perplexing trends in fluorine abundance that are not predicted by any stellar chemical evolution models.

The discovery of a subdwarf B star classified as a tidally tilted pulsator — a star with its pulsation axis aligned with the tidal axis of its binary system — greatly broadens our understanding of these objects.

Light bridges — bright, elongated features that sometimes appear in the darkest region of a sunspot — showcase a variety of behaviors such as transient brightening, intermittent jets, and light walls.

Researchers have zeroed in on 29 solar-type stars with periodic activity cycles, finding one star that shows evidence for a lessening of stellar activity akin to the deep, prolonged solar minimum from 1645 to 1715.
