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.

Planetary systems that underwent dramatic, long-lived accretion events may host planetary systems similar to our own, while ones that didn’t may instead host very close in, tightly packed planetary systems.

Observations of z≲2 massive galaxies suggest that quenching is a fast process in galaxies with mass of ≥10^11 solar masses, and that major mergers likely play a significant role in the final steps of their evolution.
Ravit Helled and David Stevenson 2017 ApJL 840 L4
A new model suggests the cores of giant planets might not be distinct from the envelopes surrounding them, unlike the traditional picture of heavy-element cores clearly separated from gaseous envelopes.
