The LITTLE THINGS survey of dwarf irregular galaxies discovers that star formation does occur in the outer disks of these galaxies in spite of the extreme nature of the environment.

New observations and analysis are presented for the planet orbiting HD 20782 with an eccentricity of 0.96. Photometric data suggests evidence of reflected light from the planet’s atmosphere.

Observations of SOHO-detected comet 322P from the ground and from Spitzer suggest it may be of asteroidal origin. If so, it has the shortest perihelion distance of any known asteroid.

Spectroscopy of 345 Type Ia supernovae is used to study the correlations between various properties of the supernovae and the properties of their host galaxies.

A morphological study of the dwarf lenticular galaxy MCG+08-22-082 reveals two cores of 10^6 solar masses and ongoing star formation. This may be an intermediate merger stage of two disk galaxies.
Catherine Zucker et al 2016 ApJ 821 113
Wide-field Infrared Survey Explorer (WISE) data from 163 compact galaxy groups confirms bimodal behavior: these galaxies are either quiescent with low star formation rates, or they are prolifically forming stars.
