The broad topic of space weather represents the constantly changing physical conditions in the near-Earth environment, which is significantly influenced by the solar wind and coronal mass ejections (CMEs). Due to their critical importance to space weather prediction, significant efforts have been made in developing first-principles-based solar wind and CME models. In the first part of this talk, I will present our recent efforts of high-fidelity solar eruption modeling from the Sun to Earth, which illustrates the new capability for space weather forecast. I will also emphasize how the unique information provided by the advanced modeling, when combined with observations, could facilitate our understanding of fundamental processes in solar and astrophysics. In the second part of this talk, I will discuss how the knowledge about our own star could help for exploration of exo-solar systems and habitable worlds in the universe. Especially, how the limited stellar observation (comparing with the solar case) can be used to constrain the wind and CME parameters. Finally, I would like to discuss the path forward with the upcoming cutting-edge observations on ground (e.g., DKIST) and in space (e.g., Parker Solar Probe, Solar Orbiter, JWST) in the context of both solar and stellar discoveries
