Home hides in a quiet corner of the #MilkyWay, a vast spiral galaxy 100,000 light-years wide with arms like luminous highways. #Earth rests in the #OrionArm, a modest spur between #Sagittarius and #Perseus, marked by the #OrionNebula and the #Pleiades cluster. There, about two-thirds from the galactic center, a yellow star glows—the #Sun. One among roughly 400 billion #stars, it shelters the only world we know, the fragile speck where every human story unfolds. #Science #Physics #Astrodon #Space
