Hydrodynamical calculations track the ejection and survival rates of dust grains produced in supernovae, demonstrating that supernovae, under the right conditions, can be significant sources of interstellar dust.
Gerardo J. M. Luna et al 2020 ApJL 902 L14
The recurrent nova T CrB is currently in the midst of an accretion high state similar to ones that may have led to past nova eruptions, suggesting that another thermonuclear runaway is likely within the next few years.

New analysis shows that, in the event of 48,000 low-Earth-orbit artificial satellites like those of SpaceX, about 1% of pixels in the Vera Rubin Observatory’s LSST nautical twilight images would need to be masked to prevent trails from damaging the data.

An study of the structure, kinematics, and orbit of a newly found stellar stream emanating from the globular cluster M92 indicates that it was likely formed very recently (during the last ~500 Myr).

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.
Jean J. Somalwar et al 2020 ApJ 902 45
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.
