Galaxies are massive structures of stars, gas, dust, and dark matter held together by gravity. Each galaxy contains billions of stars, planetary systems, and other celestial bodies. Galaxies come in a variety of sizes and shapes, including spiral, elliptical, and irregular

It's mind-blowing to imagine how massive galaxies are, all held together by gravity and filled with endless possibilities.
