Using JWST’s exceptionally fine resolution, astronomers have ruled out the presence of multiple lensed images of J0025–0145 and estimated an intrinsic Eddington ratio of 4.9 for the quasar.
New spectroscopic evidence suggests that the globular cluster NGC 6569 is actively losing stars through tidal stripping; these stars will become part of the galactic bulge field population.
The star HD 166620 is experiencing a magnetic activity lull similar to the Sun’s Maunder minimum; its Lyman-alpha surface flux is about a factor of two lower than fluxes observed during solar minimum.

Examining four binary systems in which the masses of the binary members are nearly equal, researchers find that the binary components show significant differences in magnetic activity and evolutionary stage.
Using numerical simulations, researchers show the viability of a formation pathway for Deimos that involves a catastrophic fragmentation and subsequent reaccretion into a dynamically cold orbit.
In archival data from the Dark Energy Camera Legacy Survey, researchers have discovered a possible dwarf planet with an orbit that brings it as close as 45 au to the Sun and also extends out into the Oort cloud.
