An old (>10 Gyr) Milky Way globular cluster has been found as a result of the discovery of a group of RR Lyrae variable stars roughly 7.5 kpc away toward the southern galactic plane.

Xing Lu et al 2017 ApJ 839 1

Examination of molecular lines in the Milky Way’s Central Molecular Zone suggest that star formation and strong turbulence affect the chemistry and temperature of the molecular gas on 0.1-pc scales in this cloud.

Simulations show LSST’s exoplanet detection is significantly improved by using a deep drilling cadence, with detection probabilities of ≥10% for periods of ≤5 days possible mid-way through LSST’s nominal 10 years.

Rapidly rotating, strongly magnetized pulsars without any surrounding supernova ejecta could repeatedly produce fast radio bursts via synchrotron radio emission from non-relativistic pulsar wind nebulae.

As a foundation for SFiNCs, catalogs of 15,300 X-ray and 1,630,000 mid-IR point sources are presented. ~8500 point sources are identified as probable young stellar members of 22 nearby star-forming regions.

Two infrared transients have been discovered in a nearby galaxy that are likely obscured supernovae. This discovery suggests that current optical surveys may be missing >18% of nearby core-collapse supernovae.
