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.

Analysis of a new sample of 15 Type Ia supernovae at redshift z > 1 have led to a factor of ~3 improvement in the determination of the expansion rate at z = 1.5, reducing its uncertainty to ~20%.

New analysis of data from the Pierre Auger Observatory provides evidence for anisotropy in the arrival directions of ultra-high-energy cosmic rays — indicative of excess arrivals from strong, nearby sources.

The HR 4796A ringlike debris disk is revealed by Hubble to be embedded within a much larger, morphologically complex, and biaxially asymmetric exo-ring scattering structure.
