Four occultation measurements of the plutino object (208996) 2003 AZ84 reveal that it is a triaxial body with a topographic feature that may be an abrupt chasm 23 km wide and at least 8 km deep.

The sample of 18,000 galaxies in the CANDELS/GOODS-South field ( 0.5 ≤ z ≤ 2.0) suggest that the black hole accretion rate is more strongly correlated with host galaxy stellar mass than with star formation rate.

GAlaxy Evolution and Assembly (GAEA), a model that includes strong stellar-driven outflows, is able to reproduce the observed shape and redshift evolution of ultraviolet and optical luminosity functions.

A strongly lensed pair of super star-clusters is presented at z = 3.2222 separated by ~300 pc, with magnitudes m≃30.6 and effective radius of 30 pc each. These show signs of both young and evolved stars.

Dwarf-planet-sized objects can stir eccentricities and inclinations of particles in a cold debris disk, but the addition of a giant planet in the disk can act as a stabilizing agent of the orbits of cometary nuclei.

ALMA observations confirmed the Boomerang Nebula as the coldest known object in the universe, with a massive high-speed outflow that has cooled significantly below the cosmic background temperature.
