HST observations of active asteroid 288P/300163 reveal the small vertical extent of its surface dust sheet, ejection speeds well below the nucleus escape speed, and the possibility of a binary nucleus.

Spitzer observations of classical Cepheids establish a precise distance of 62 ± 0.3 kpc to the SMC. They also confirm the SMC is tilted, such that the eastern side is 20 kpc closer than the western side.

A catalog is created of solar filaments that formed between 1988 and 2013. Statistical analysis reveals relations between the latitudinal location of the filaments and their tilt angles and directions.

The properties of jets produced by black holes may be primarily dependent on the properties of the plasma near the black hole, rather than on parameters like the black hole’s mass or spin.

Observations of the Moon occulting 18 stellar sources led to the detection of four angular diameters and two binary stars. Resolution limits of this study were 2 mas for diameters and 4 mas for separations.
