Degeneracies are shown to exist between transmission spectra of super-Earth planets with different masses and compositions, indicating difficulty in determining a planet’s mass from transmission spectroscopy alone.

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.

Data from the Dawn spacecraft reveals that the Occator crater on Ceres, a dwarf planet in the main asteroid belt, contains a thin layer of haze that varies diurnally, likely produced by sublimation activity.

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.
V. Strazzullo et al 2016 ApJL 833 L20
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.
