An extremely high-quality spectrum from Keck-HIRES of Kepler-11 reveal new values for its fundamental parameters that raise the calculated densities of its 6 planets by 20–95%, making them more typical.
Daniel Tamayo et al 2017 ApJL 840 L19
The configuration of the TRAPPIST-1 system of 7 planets is consistent with a history of slow, convergent disk migration resulting in its current long-lived resonant or near-resonant set of orbits.

The Large Magellanic Cloud Supernova Remnant Sample — the most complete SNR sample in any galaxy — implies SNRs should be the dominant mechanism for the production and acceleration of cosmic rays.

A complete 7-year set of IBEX observations strongly support a secondary source of energetic neutral atoms for the IBEX Ribbon, a region of enhanced energetic-neutral-atom emissions.

Supermassive black holes have been detected in two Virgo ultracompact dwarf galaxies, VUCD3 and M59cO. Their properties support a picture in which the UCDs are tidally stripped remnants of larger galaxies.

The PDS 11 binary system is a new addition to the interesting class of old, dusty, wide binary classical T Tauri systems in which both components are actively accreting.
