The spectral signature of an unusual cation was recently detected for the first time in diffuse interstellar clouds. New laboratory experiments examine its absorption spectrum to compare with observations.

A database of 2D bulge–disk decompositions for 14,233 SDSS galaxies is presented and used to examine the properties of bulges residing in the local universe (0.005 < z < 0.05).

The radio source VLA J213002.08+120904 (found at 2.2 kpc) is the first black hole X-ray binary discovered in quiescence outside of a globular cluster. There’s likely a large population of such objects in our galaxy.

High-resolution imaging of 382 Kepler Objects of Interest reveals a paucity of binary companions at solar-system scales, suggesting that the influence of a binary companion prevents planetary-system formation.

New observations of 14 faint, X-ray selected AGN indicate that a significant population of faint z ~ 5−6 AGNs should be detectable in deep X-ray surveys, but we don’t observe this. Why not?

Two supernovae are thought to have occurred within 100 pc in the last 10 Myr. What impact did they have on life on Earth? This study examines the many effects potentially due to these supernovae.
