Properties like metal distribution and ionization levels can vary greatly from simulation to simulation; future work will examine how these properties affect observable quantities.
Starlight polarimetry measurements reveal the magnetic field properties of the Southern Coalsack Nebula and allow researchers to study polarization in the nebula as well as a background structure.
An analysis of nearly 60 ultra-diffuse galaxies suggest that these small galaxies do not belong to their own class, but rather are at the diffuse end of spheroidal galaxies.
A study of solar flares finds no clear correlation between the three-dimensional magnetic free energy and the peak flux of a flare; random perturbations may trigger flares rather than a simple release of pent-up energy.
New JWST data reveal the star formation history of the Local Group galaxy Wolf–Lundmark–Melotte and yield the deepest color–magnitude diagram for any galaxy other than Milky Way satellites.
JWST data improve upon past ground-based data of the five Trojan asteroids that will be visited by NASA’s Lucy mission; the next Lucy mission flyby will take place in April 2025.
