The term "galactic" refers to anything related to a galaxy, which is a massive system of stars, gas, dust, and dark matter bound together by gravity. Our own galaxy, the Milky Way, is just one of billions in the universe. Galaxies can vary in size and shape, including spiral, elliptical, and irregular forms. In astronomy, "galactic" often describes phenomena or objects that occur on a large scale, such as galactic clusters or galactic centers. These areas can contain millions of stars and other celestial bodies, playing a crucial role in the study of the universe's structure and evolution.
