Using a sample of 190,000 HST galaxies, the effective radius of galaxies is shown to decrease with higher redshift in the range z=0–10.

Eight newly-detected dwarf spheroidal satellite galaxies of the Milky Way were searched for indirect evidence of dark matter in the form of excess gamma-ray radiation. None was found.

A survey of brown dwarfs finds that their spin rate shows little or no evidence of rotational braking between 1-10 Myr, in contrast to low-mass stars.

The first binary near-Earth asteroid imaged, DP107, was again imaged as it passed Earth in a 2008 fly-by. Resulting estimates of the mutual orbit, component masses, and spin periods are reported.

Extremely faint X-ray pulsations are observed in a millisecond pulsar/LMXB transition object, providing clues about the nature of accretion flows onto neutron stars during quiescent states.
