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.

~3-AU resolution imaging of the protoplanetary disk around TW Hya with ALMA indicates a deficit of mm-sized grains within the most prominent gap at 22 AU, suggesting an unseen planet has cleared it.

HST far-UV direct images of Europa, taken as the moon transited Jupiter’s face, were used to measure absorption from gas or aerosols beyond the Europa limb. Possible signs of plume activity were detected.

Calculations show WFIRST should be able to detect and characterize the masses of free-floating planets down to or below super-Earths throughout the Galaxy during its entire microlensing survey.

Observations from the Advanced Composition Explorer spacecraft suggest the fast solar wind originates from coronal holes, and the slow solar wind has a component originating from closed magnetic loops.
