The circumgalactic medium (CGM) is crucial for galaxy formation, predominantly hot and requiring X-ray observations for study. Our position within the Milky Way provides a unique opportunity to explore the CGM of this spiral galaxy. Recent developments challenge old ideas about its thermal structure, revealing a complex X-ray emission model with temperatures near the Galaxy's virial temperature (? 0.18 keV) and a super-virial range (0.4 ? 1.2 keV). There is also evidence of super-solar abundances of N, Ne, and Mg in the Milky Way's CGM. This newly discovered super-virial temperature gas and super-solar abundances are likely influenced by hot outflows from star formation activity throughout the Galactic disk. Toward the Galactic center, the Milky Way's CGM interacts with X-ray bright eROSITA bubbles, showcasing Galactic Center feedback by injecting energy and momentum into the extended CGM. In my presentation, I will discuss our latest findings on thermal structure of the extended Milky Way CGM and the Galactic bubbles.
