Look! A Lensing!
Microlensing events can be predicted by following the path of high proper motion stars. In this paper, the authors do just that with Gaia DR2 data.
Hunting for Stellar Streams
A newly discovered stellar stream may be the long-searched for tidal debris from the Milky Way’s largest globular cluster.

Stars that exploded just a little bit
Partly burnt stars are zipping through space, carrying a strange mix of elements. What can we learn by observing them?
A Shocking Model of FRBs
Multiple models have been proposed to explain the intriguing properties of FRBs, but this new model provides one of the most detailed scenarios yet, consistent with properties of current observed FRBs.
