ZBLLAC is a database containing calibrated spectra for 295 BL Lacertae objects — low-power active galactic nuclei whose relativistic jets are pointed near to our line of sight — with firm redshifts provided for ~35% of them.

New observations of ultra-diffuse galaxies (UDGs) indicate that the highest globular cluster abundances are found in cluster UDGs, and there may be a correlation between globular cluster abundance and stellar mass.

Numerical simulations of Proxima Centauri’s stellar wind indicate stellar wind dynamic pressures at the newly discovered planet Proxima Centauri c that are comparable to those at present-day Earth.

A new analysis of the optical data of galaxies in the foreground of FRB 190608 completes an end-to-end study of matter distribution along a fast radio burst sightline, the first study of its kind.

ALMA has made the first unambiguous detection of cyclopropenylidene, the second known cyclic molecule in Titan’s atmosphere along with benzene and the first time this molecule has been detected in a planetary atmosphere.

Venus’s atmosphere may have collapsed into a runaway greenhouse state due to variations in its orbital eccentricity driven by migration of Jupiter’s orbit in the early history of our solar system.
