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.

A team has created a new, independent vetting pipeline to discover planets in Transiting Exoplanet Survey Satellite data that might otherwise be missed, bolstering the numbers of known close-in giant exoplanets.

Though simulations of the convective–radiative boundary within a star have different outcomes on brief timescales when different criteria are implemented, they reach the same state over long timescales.

Among compact objects, white dwarfs are the likeliest source of gravitational microlensing events in globular clusters, which are good places to search for these events, especially if they are densely packed.

The first quantitative maps of iron oxide and other quantities in the Moon’s polar regions reveal features like small young craters in fine detail, giving a new view of the proposed Artemis III landing site.
