The likely and potential contact binaries discovered in the dynamically cold classical population of the Kuiper Belt display very red/ultra-red colors, suggesting that these binaries likely formed in situ.
Kristen Garofali et al 2019 ApJ 880 8
The first candidate colliding-wind binary — massive binaries in which both stars emit strong stellar winds that collide between the stars, producing shocks — has been identified in M33.

Newly emerging techniques and tools can be used to overcome many of the challenges — like instrumental noise, search biases, and host star variability — inherent in hunting for transiting exoplanet signals.

Two decades of Optical Gravitational Lensing Experiment (OGLE) data have uncovered 12,660 spotted variable stars toward and inside the galactic bulge, the vast majority of which are giants.

The long-running search for a giant transiting planet in an open cluster remains fruitless after a recent candidate, a hot Saturn orbiting the late F star K2-308, is shown to not belong to the open cluster NGC 1817 after all.

Early results from Col-OSSOS, which is acquiring g, r, and J photometry of 100 trans-Neptunian objects, suggest that the primordial solar system protoplanetesimal disk is neutral-class rather than red-class dominated.
