Simona Giacintucci et al 2019 ApJ 880 70
The detection and confirmation of several more radio minihalos — diffuse synchrotron sources of unknown origin — support the picture in which that most, if not all, cool cores in massive clusters contain a minihalo.

Models suggest that Neptune-sized planets with relatively low insolation and small semimajor axes are the most conducive to reflected light phase curve studies with the Transiting Exoplanet Survey Satellite (TESS).
Matteo Monelli and Ignacio Trujillo 2019 ApJL 880 L11
Distance measurements using the tip of the red giant branch place the second galaxy claimed to be missing dark matter, NGC 1052-DF4, 6 Mpc closer than previously determined, making its properties less extreme.
Xueying Guo et al 2019 ApJ 880 64
A comparison of the Spitzer- and Kepler-bandpass apparent radii of a sample of 28 transiting super-Earths/mini-Neptunes around M/K dwarfs reveals that these small, temperate planets fall into two populations.
Edward G. Schmidt 2019 ApJL 880 L7
A search for stars exhibiting peculiar dipping behavior like Boyajian’s star using data from the Northern Sky Variability Survey and the All Sky Automated Survey for Supernovae turned up 21 possible analogous dippers.

The HEPD on board the China Seismo-Electromagnetic Satellite (CSES) will precisely observe electrons, protons, and light nuclei, monitoring perturbations in the iono-magnetosphere and inner Van Allen radiation belts.
