In the Leo I group, BST1047+1156, the lowest surface brightness object ever detected via integrated light, may be a disrupting tidal dwarf or a preexisting galaxy with a recent burst of star formation.

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 best candidates of exomoon-hosting planets are identified from the Kepler database on the basis of dynamical arguments, producing a list of 54 planets with putative “visible” satellites.

Historical auroral records from East Asia suggest that the great geomagnetic storm of 1872 February was as extreme as the Carrington Event, the benchmark geomagnetic storm of 1859 September.

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.
