An 18-year span of precision radial velocity measurements reveal the presence of a 6-planet system orbiting the G0V star HD 34445 with periods of 1057, 215, 118, 49, 677, and 5700 days.

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.
