The NRAO and the ngVLA project convened a Special Session titled "Space Weather on Other Worlds" on January 9, 2024 at the American Astronomical Society meeting in New Orleans, LA.

The session highlighted recent scientific breakthroughs in characterizing space weather on other worlds with current facilities; described planned near- and long-term improvements for ground- and space-based facilities; discussed major scientific leaps likely to result from next-generation facilities across the electromagnetic spectrum; and reviewed the highest-priority themes in this area for the state-of-the-art observatories to be commissioned in the next decade.

The session featured these invited oral presentations, whose abstracts are available here:

219.01 Bin Chen (NJIT), The Space Weather Environment Around Stars: Insights from Spatially Resolved Radio Spectral Observations of the Sun

219.02 Jackie Villadsen (Bucknell University),  Stellar Activity and Star-Planet Interaction in Radio

219.03 Sebastian Pineda (University of Colorado), Assessing the Stellar Magnetospheric Environments Impacting Exoplanets Across Theory and Observation

219.04 Cynthia Froning (Southwest Research Institute), Characteristics, Activity, and Evolution of XUV Emission from Exoplanet Host Stars
