A search through a sample of old halo stars revealed a new, low-mass, debris stream on a polar orbit that occupies a region of 10–20 kpc from the galactic center and is associated with two globular clusters.

A full catalog of solar flares is presented as observed by the EIT on board the SOHO spacecraft and the GOES spacecraft over a span from 1997 to 2010, providing a valuable resource for solar flare prediction studies.

Climate modeling suggests that hurricane genesis is most favorable for terrestrial exoplanets in the habitable zones of late-type M dwarf stars, and less favorable on slowly rotating terrestrial exoplanets.

Stephen R. Kane et al 2020 AJ 160 81

Dynamical models suggest that the width of the habitable zone for earlier-type stars allows for more terrestrial planets in the habitable zone than around late-type stars.

Ran Si et al 2020 ApJL 898 L34

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.
