Hubble observations are used to search for new very small satellites of Haumea, a dwarf planet with two known satellites. Satellites similar in size to the small moons of Pluto are ruled out.

A wide-field stellar map of Cen A (a close massive elliptical galaxy) reveals previously unknown streams, shells, and 13 dwarf satellite candidates, including the first tidally disrupting dwarf found around Cen A.

Planetesimals captured by disks around gas giants typically spiral rapidly into the planet. Planetesimal orbits that are initially retrograde decay faster, and high gas drag can turn them to prograde orbits.

3D simulations of protoplanetary disks show that ALMA has the capability to detect the overdense spiral arms and clumps representing precursors to the formation of gas giant planets.

According to recent astrobiological experiments in which varied chemical conditions are irradiated with UV light, more glycine is produced when ammonia and methane are present.

A detailed study of the Fermi-LAT observations relevant to the recent LIGO gravitational-wave detection found no gamma-ray counterparts to GW150914.
