Research continues to show that seemingly simple globular clusters are actually composed of multiple populations of stars, as is the case for Messier 92, which contains a centrally concentrated metal-poor population.

Pulsars — rapidly spinning cores of exploded stars — are the best timepieces in the universe, and their regular pulses can be used to aid in spacecraft navigation.

Laboratory experiments and simulations suggest that meteoroids streaking through the thick, nitrogen- and carbon-rich atmosphere of Saturn’s moon Titan can generate a small but significant amount of organic molecules.

Simulations suggest that the disk of material that forms around a stellar-mass black hole as it accretes gas from its surroundings is supported by magnetic pressure and is thermally stable.

Many galaxies with redshifts between 4 and 7 observed by JWST appear to be blue and dustless, supporting the picture of dust within galaxies building up over cosmic time.

What was first categorized as a planet turns out to be a very low-mass star, barely massive enough to fuse hydrogen into helium; further study of the star constrained its activity level and rotation period.
