Searches for gravitational waves from 200 pulsars using data from the first observing run of the Advanced LIGO detectors yielded no significant detections, but they were able to set constraining upper limits.

31 out of 48 magnetic clouds observed near Earth between 2008–2012 can be clearly connected with a coronal mass ejection that is trackable in STEREO imagery all the way from the Sun to near 1 AU.

Dante Minniti et al 2017 ApJL 838 L14

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.

Z. G. Dai et al 2017 ApJL 838 L7

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.
