A study of interacting vs. spiral galaxies demonstrates that either the efficiency of star formation per region is higher in interacting galaxies, or there is more interstellar gas per star-forming clump in them.

If hot Jupiters gain their large sizes by inflation due to stellar irradiation, then non-inflated gas giants at moderate orbital periods could “re-inflate” as their host stars evolve.

ALMA observations indicate the presence of a gap and a ring in the protoplanetary disk around Tw Hya, located at ~25 and ~41 AU from the central star, and associated with the CO snow line at ~30 AU.

Newly discovered “super spiral galaxies” — giant, massive spiral galaxies as optically luminous as elliptical brightest cluster galaxies — may be a remnant population of unquenched, massive disk galaxies.

Two new Trojan asteroids were discovered in stable orbits around Neptune’s leading Lagrange point — the 8th and 9th such objects found. Neptune Trojans help constrain the evolution of our solar system.
M. McDonald et al 2016 ApJ 817 86
A study of the 90 brightest cluster galaxies suggests that the dominant mode fueling their star formation may have recently transitioned from galaxy–galaxy interactions to cooling of the intracluster medium.
