A galaxy is a large collection of stars, gas, dust, and dark matter bound together by gravity. Galaxies come in many shapes and sizes, ranging from small dwarf galaxies to giant elliptical galaxies. Our own Milky Way a barred spiral galaxy that contains hundreds of billions of stars. Galaxies are typically separated by vast distances filled with intergalactic gas and dust. The study of galaxies has revealed much about the structure and evolution of the Universe as a whole. Astronomers have discovered that most galaxies contain supermassive black holes at their centers, which can be millions or even billions of times more massive than our Sun. By studying these distant objects we can learn more about how our own galaxy formed and evolved over time.
