The Transiting Exoplanet Survey Satellite (TESS) will obtain 2-min-cadence observations of 200,000–400,000 stars selected for their likelihood of hosting small, detectable transiting planets.

The mass of a supermassive black hole in the brightest cluster galaxy of MACS J1149.5+2223 at z = 0.54 is estimated using one of the multiply lensed images of a background spiral galaxy at z = 1.49.

Two new globular clusters, RLGC 1 and RLGC 2, have been serendipitously discovered in infared survey data in the far-half region of the Milky Way, and they may belong to the halo of the Milky Way.

Photometric Kepler data of 87 solar-type stars is used to to detect and characterize stellar magnetic cycles through asteroseismology; >60% of the stars show evidence for (quasi-)periodic variations in their frequency shifts.
Ang Liu et al 2018 ApJ 863 102
An investigation of the dynamics of the galaxy cluster A2142 reveal 868 members and a number of substructures in the galaxy distribution that suggest multiple minor mergers in this cluster’s past.

Analysis of radial-velocity observations of Kepler data indicates that cold Jupiters appear three times more often around hosts of super Earths than they do around field stars.
