APOGEE, part of SDSS-III, has completed its systematic, homogeneous spectroscopic survey sampling all major populations of the Milky Way, gathering half a million high-resolution infrared spectra for 146,000 stars.

Eight NuSTAR sources with extremely hard X-ray spectra are identified as highly obscured active galactic nuclei, including three robust Compton-thick AGN at low redshift and one likely one at higher redshift.
A. K. Dupree et al 2017 ApJL 846 L1
Two populations of rotating stars — one rapidly rotating, and the other younger and slowly rotating — have been discovered in the young (~200 Myr) Large Magellanic Cloud (LMC) cluster NGC 1866.

A supervised learning algorithm has been used to detect 60 high-probability non-transiting short-period giant planets in the Kepler field, after classifying ~140,000 Kepler stars.

The first all-sky map of far-ultraviolet fluorescent molecular hydrogen emission in the Milky Way covers 76% of the sky and allows for future exploration of the galaxy’s interstellar medium.

Photochemically generated hazes and equilibrium condensate clouds can be distinguished in observations of exoplanet atmospheres based on the transmission spectra measured at the planet limbs.
