51 candidate “blueberry galaxies” are found — dwarf starburst galaxies with very small sizes (<1 kpc) and very high ionization, with some of the lowest stellar masses and metallicities of star-forming galaxies.
Davide Lazzati et al 2017 ApJL 848 L6
New numerical simulations of the prompt emission of short-duration gamma-ray bursts provide a model in which X-ray transients of a few to ~10 s arise, delayed by a few seconds from the time of the merger.

The highly collimated SiO jet from the V380 Ori NE star-forming region shows signs of precession of the jet axis, with a driving source that may belong to a non-coplanar binary system.

Data from Galaxy Zoo 2 shows that the fraction of low surface brightness galaxies hosting strong bars is systematically lower than that found for high surface brightness galaxies.

New imaging of a small, fan-shaped reflection nebula in NGC 1333 suggest that the nebula’s fluctuating brightness is due to varying incident radiation emanating from HBC 340, the protostar illuminating it.

Disk thicknesses were measured in a sample of ~100 edge-on Hubble Frontier Field galaxies with bulges. The scale heights measured were proportional to galactic mass.
