A possible microlensing event is reported near the center of globular cluster NGC 6553. The lensing object could be the first stellar-mass black hole found in a globular cluster.

The full Spitzer catalog of 3239 candidate Young Stellar Objects from 18 molecular clouds is presented. Infrared spectral indices, bolometric luminosities, and bolometric temperatures are given for each.

Deep spectroscopic integrations of the largest luminous Lyα nebula associated with the quasar UM287 imply the presence of remarkably dense and compact gas clouds.

The amount of dust produced by R Coronae Borealis stars (a rare class of variable star) is comparable to the amounts produced by novae or born-again post-AGB stars.

23% of the brightest radio-loud AGN weren’t detected by Fermi-LAT, partly because of an instrumental selection effect and partly due to their lower Doppler boosting factors.

E3 appears to be the first bona fide Galactic old globular cluster where no sign of self-enrichment is found. This suggests that self-enrichment may not be feasible in clusters of such low mass.
