Stellar eruptions in the form of coronal mass ejections (CME) often result in major impact on planets. In this talk, we will visualize stellar-planet connections based on simulations and observations of the April 2023 and May 2024 CMEs. Both CME events resulted in extreme geomagnetic responses. In-situ measurements such as those from the Magnetospheric Multiscale mission enabled a new view of Sun-Earth magnetic connection and the CME space weather impact. We will explore the CME multi-messenger impact on multiple planets. Highlight will include the transformation of Earth's magnetosphere from a usual windsock-like configuration with a long magnetotail to one with wings and no tail. We will see first-hand how solar-magnetosphere research carries the power to advance planetary and star-exoplanet science.
