The Explosive Sun and its Relevance for Exoplanet Space Weather

The Sun and its variability offer an excellent laboratory for studying fundamental physical processes in astrophysical plasmas, such as dynamos, shocks, and particle acceleration. We have learned a great deal on the nature of solar eruptions over the last couple of decades and how they drive interplanetary Space Weather. This knowledge can be used to inform searches of and assessment for habitable exoplanet environments.
In this talk, I review the observations of coronal mass ejections (CMEs) and their sources to provide an up-to-date picture of their magnetic nature and properties. I briefly discuss how CMEs drive Space Weather and give my personal view on how these observations could be used to assess exoplanet habitability. I finally inform on the status of the Parker Solar Probe, the first exploration into a stellar atmosphere and how this ambitious mission will impact astrophysics in the years ahead.
