Updated Chandra imaging covering the last 16 years indicate that supernova 1987A’s blast wave is now leaving the dense equatorial region, marking a change in evolutionary phase of the remnant.

Prompt planetesimal formation is shown to be possible early on beyond the snow line via known physical processes. This leads to a broad and massive belt of planetesimals well outside the snow line.

Observations of 91 central galaxies show that quiescent galaxies host more massive black holes than star-forming galaxies, supporting the theory that AGN feedback may suppress star formation.

A list of habitable-zone (HZ) exoplanet candidates from Kepler Q1–Q17 data includes 104 candidates within the optimistic HZ and 20 candidates with radii of <2 Earth radii within the conservative HZ.

Kepler-80, a system of five tightly spaced inner planets, is analyzed. The system is found to be long-term stable, and the four outer planets are discovered to be in a dynamically rare configuration.

A thin dark matter disk could be discovered in the Milky Way by measuring the relationship between the midplane densities and scale heights of interstellar gas, but current models/data are inadequate.
