New observations of an on-disk prominence bubble around a filament barb has allowed for a 3D reconstruction of its structure, allowing for exploration of how the boundary is shaped by underlying magnetic fields.

Analysis of 4,050 wide binary star systems involving a white dwarf and usually a main-sequence star allowed for age determinations for 3,551 white dwarfs that can likely be extrapolated to their low-mass companions.

The properties of ~500 “yellowballs” have been measured in a pilot region of the galactic plane, demonstrating that ~20–30% of these sources contain high-mass star formation capable of becoming expanding H II regions.

A high-resolution geologic map is presented for the southwest peak-ring area of the Schrödinger basin, a region that would be well-suited to a robotic lunar sample return mission in the future.
Michael Zevin et al 2021 ApJ 910 152
Analysis of the second LIGO–Virgo catalog of gravitational-wave transients suggetss that a mixture of formation channels for the binaries is strongly preferred over any single channel dominating the detected population.

The second data release (DR2) of the NOIRLab Source Catalog contains over 3.9 billion unique objects with 68 billion individual source measurements, covering ~35,000 square degrees of the sky.
