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.

Analysis of the properties and evolution of protoplanetary disks around stellar binaries reveals that these are in many ways more favorable sites for planet formation than disks around single stars.

A supernova gravitationally lensed by a galaxy cluster appeared as a first image in Nov 2014. It was predicted to reappear in Dec 2015 in a second host-galaxy image — and the prediction was successful!
