The first data release from SDSS-IV, DR13, makes publicly available the first 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA, as well as presenting data from eBOSS and APOGEE.

Deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way, Columba I and Triangulum II, suggest both have exclusively old and metal-poor stellar populations.

Rodrigo Luger et al 2017 ApJ 851 94

JWST should be able to detect ~10–20 occultations per year of TRAPPIST-1 b and c, which occur as one planet blocks the thermal- and reflected-light signals of the other as it passes in front.

Anne J. Verbiscer et al 2018 ApJL 852 L35

New Horizons’ observations of Pluto’s largest two moons suggest that Nix and Hydra scatter visible light preferentially in the forward direction, unlike most icy satellites in the outer solar system.

Sofia-Paraskevi Moschou et al 2017 ApJ 850 191

A coronal mass ejection may have been the cause of the observed continuous X-ray absorption of the 1997 August 30 superflare on the eclipsing binary Algol (known as the Demon Star).

Jason Rhodes et al 2017 ApJS 233 21

LSST’s high-cadence, deep optical photometry will combine well with Euclid’s high-resolution optical photometry and near-IR photometry and spectroscopy to address a wide range of astrophysical questions.
