Citizen-scientist identification of 25 new candidate hybrid morphology radio sources — rare galaxies that display different Fanaroff–Riley classes on opposite sides of their nuclei — reveal this to be a diverse class.

Doubling in 41/44 GHz flux density on ~20-minute timescales was observed in the magnetar SGR J1745−29 — consistent with a model in which pulsed emission is generated in the magnetar’s magnetosphere.

Historical documents such as sunspot drawings and reports of low-latitude auroral displays from East Asia demonstrate that an extreme magnetic storm must have occurred in September of 1770.

Observations from HST suggest that no nucleus or fragments greater than 30 meters in size survived after asteroid P/2016 G1 was activated and disrupted as it approached the Sun in 2016.

SkyNet, a new general-purpose nuclear reaction network that evolves the abundances of nuclear species through nuclear reactions, can be used to explore processes in the early universe and in the life cycles of stars.

A search for transient hard X-ray emission in the quiet solar corona with the Nuclear Spectroscopic Telescope Array (NuSTAR) satellite resulted in no detections, setting upper limits on hard X-ray brightenings.
