For some planet types (like warm super-Earths), occurrence rates do not correlate with metallicity. For others (like warm sub-Neptunes), more of these planets are found around higher metallicity stars.

The Wide-field Infrared Survey Explorer’s AllWISE Data Release has produced two large (>1 million sources) catalogs of active galactic nucleus (AGN) candidates identified across 30,093 deg2 of extragalactic sky.

Data from GALEX observations of the enigmatic variable star KIC 8462852 show no coherent near-UV variability in the system on 10–100 s or month timescales, but a 3% decrease in brightness the following year.

Revised host-star radii measured in the K2-HERMES project cast severe doubt on three candidate planets, all of which now have inferred radii well in excess of the largest known inflated Jovian planets.
