Kepler observations of the binary system 16 Cyg A&B are used to demonstrate that stellar properties like age and composition can be reliably constrained with asteroseismic analysis.

Victor P. Debattista et al 2015 ApJ 812 L16

Measurement of the stellar velocities of red giant stars in the inner Milky Way suggest the presence of a thin, rapidly rotating, nuclear disk perpendicular to the galactic bar and extending to ~1 kpc.

This study announces 1.4 million active galactic nuclei (AGN) found with the Wide-field Infrared Survey Explorer, including ~1.1 million previously uncatalogued AGN.

F. Hammer et al 2015 ApJ 813 110

Analysis of the Magellanic Stream suggest it can be decomposed into two filaments representing ram-pressure tails. There is also further evidence that the Magellanic Clouds collided 200-300 Myr ago.

Simulations show that jets that form in the solar chromosphere are projected farther outward when the coronal temperature is lower. They’re shorter when the coronal temperature is higher.

Results from the ExploreNEOs program suggest that roughly 100 near-Earth asteroids with diameters of 1 km or more are actually dormant short-period comets (i.e., asteroidal objects of cometary origin).
