New high resolution imaging of a light-scattering dust ring and halo around the young star HD 35841 reveal the highly inclined (i = 85°) ring of debris down to a projected separation of ~12 AU for the first time.

CRLE, a serendipitously discovered dusty, starbursting galaxy at z = 5.667, is the highest-redshift, most luminous starburst in the COSMOS field, forming stars at a rate of at least 1500 M_⊙/yr in a region only ~3 kpc across.

Based on measurements of radial velocities of 800 individual stars, the globular cluster M5 is shown to have one of the cleanest and most coherent rotation patterns ever observed for globular clusters.

An isolated cold galactic disk can become violently unstable, leading to fragmentation and formation of stellar clumps that increase the stellar disk velocity dispersion, forming an isolated lenticular galaxy.

The visual geometric albedo of the hot Jupiter WASP-104b is lower than 0.03 at 95% confidence, making it one of the least-reflective planets found to date.
