The second catalog of gamma-ray bursts detected with Fermi’s Large Area Telescope is released, covering the first 10 years of operations and including 186 gamma-ray bursts.
Valentin Christiaens et al 2019 ApJL 877 L33
Observations with the Very Large Telescope have revealed evidence for a circumplanetary disk surrounding the protoplanet PDS 70 b (even as ALMA observations have recently indicated a similar disk around PDS 70 c).

ALMA’s spatially resolved millimeter maps of Neptune provide important constraints on the atmospheric structure and dynamics of the planet, revealing details like unaccounted-for complex structure at the equator.
Alexander H. Riley et al 2019 ApJ 878 8
New data from the Fermi Large Area Telescope suggest that the debris-disk-hosting main-sequence star ε Eridani may be a source of gamma rays — the only main-sequence source of gamma-rays known besides the Sun.

Analysis of the light curves of a set of 32 galactic classical novae — thermonuclear explosions of white-dwarfs — provides the distances and white-dwarf masses using a single, uniform method.
