A very large star-forming galaxy, G6025, has been discovered and confirmed at z = 3.721; curiously, its stellar population parameters and dust reddening are are similar to those of smaller galaxies at comparable redshifts.

The James Webb Space Telescope should be able to detect a large number of the infrared coronal lines predicted from the theorized intermediate-mass black holes (black holes with mass 100–100,000 M⊙).

In a new model of the early universe, star formation is ignited in low-mass halos by a passing shock front in cosmic filaments that is self-sustained by energy injection from supernova explosions.

New high resolution imaging of a light-scattering dust ring and halo around the young star HD 35841 reveal the highly inclined (i = 85°) ring of debris down to a projected separation of ~12 AU for the first time.
