The black-hole masses are calculated for nearly 300,000 active galactic nuclei using broad emission line data from the Sloan Digital Sky Survey (SDSS) Quasar Data Release 12 (DR12Q).

A survey has detected CH2NH, a precursor to the amino acid glycine, in 8 sources in the ISM. These observations may improve our understanding of how the ingredients for life came to be on Earth.

A decade-long survey of the activity of 50 long-period comets in our solar system shows that dynamically new comets have a higher level of activity and develop more symmetric comae.

HST images of the low-mass cluster Cl J1449+0856, likely a typical progenitor of an average massive cluster today, show a red population in the core that is a mixture of quiescent and dusty star-forming galaxies.

Spitzer infrared catalogs of stars are presented for nearby, mostly large star-forming galaxies — including 859,000 sources in Andromeda galaxy (M31) and 116,000 sources in another 15 galaxies.
