The masses of 1,120 galaxy candidates at redshifts of 6.5 < z < 13.5 are consistent with existing cosmological models, though some of the most massive galaxies may require a high star-formation efficiency.
A detailed study of the eruption of a multifilament system on the Sun shows how three filaments in different configurations combined to form one long filament and a double-decker configuration.
A low-complexity statistical process helps to vet potential technosignature signals, weeding out obvious human-originated radio interference and highlighting interfering signals that are less obvious.

Though more work is needed to say for certain, including the magnetization and magnetic susceptibility from Landau quantization may provide a solution to the magnetar heating problem.
Researchers have discovered the largest radio jet yet at a redshift of z > 4, spanning a distance of 215,000 light-years; this discovery also shows that even low-mass black holes can produce powerful jets.
A comprehensive survey of the extensive filamentary nebula that surrounds the central galaxy of the Perseus Cluster affirms previous suggestions that magnetic fields play an important role in the life of the nebula.
