From a population of known near-Earth objects (NEOs), a manual search of all-sky infrared NEOWISE data has identified observations of more than 200 of these NEOs not previously characterized.

The decreasing orbital period of the hot Jupiter WASP-4b is not due to tidal decay, but rather due to the acceleration of the WASP-4 system toward us along our line of sight, possibly caused by a wide companion.

A catalog of 99,203 probable wide binary systems identified from Gaia data demonstrates that the distribution of projected physical separation for probable wide binaries is a simple exponential tail.

Precision photometry of WASP-47 from the K2 mission adds WASP-47b and possibly also WASP-47e to the growing list of dark, short-period giant planets, setting us up to explore factors that contribute to low planetary albedos.

Evaluation shows that the rocket-borne High-Resolution Coronal Imager (Hi-C) can resolve individual coronal strands as small as ~202 km, indicating resolving power greater than that of the Solar Dynamics Observatory’s AIA.

The fastest rotating star in the Milky Way, runaway star LAMOST J040643.69+542347.8, has a projected rotational velocity of 540 km/s — roughly 100 km/s faster than the previous record holder.
