A new methodology, based on a careful study of magnetic induced atomic transitions, is used to provide the first estimates of the coronal magnetic field strength using spectroscopic data from Hinode.

Analysis of bright ephemeral features on Titan’s north pole suggest that they represent either broad specular reflection off of a recently wetted surface or a near-surface fog — both owing to probable recent rainfalls.

Radio polarimetric imaging indicates a magnetic structure within the Stephan’s Quintet galaxy system spanning at least 60 × 40 × 20 kpc, with a strength at least as high as that previously detected within large spiral galaxies.

A new catalog presents 306 holes identified in the neutral atomic hydrogen of 41 gas-rich dwarf galaxies in LITTLE THINGS, likely generated during the process of star formation.

Hydrodynamic modeling of tilt instabilities in accretion disks around binary systems shows that detached circumplanetary disks may commonly be misaligned relative to the planetary orbital plane.
Adam Wheeler et al 2020 ApJ 898 58
A new approach is used to obtain detailed abundances from low-resolution LAMOST spectra for millions of stars, to a precision of 0.05–0.23 dex — providing unprecedented perspective on chemistry across the Milky Way.
