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.

CRLE, a serendipitously discovered dusty, starbursting galaxy at z = 5.667, is the highest-redshift, most luminous starburst in the COSMOS field, forming stars at a rate of at least 1500 M_⊙/yr in a region only ~3 kpc across.

The Hubble Deep UV Legacy Survey provides the deepest high-resolution ultraviolet data over such a large area — 100 square arcmin — taken to date.
