@astralfrontiers: Galaxies come in an incredible range of sizes, from tiny dwarf galaxies with just a few million stars to giant galaxies containing trillions of stars. The Milky Way is about 100,000 light years across, but many galaxies are far smaller while others stretch several times wider. Their size depends on how they formed, how much matter they contain, and whether they have merged with other galaxies over billions of years. This comparison shows just how diverse our universe really is. Which galaxy surprised you the most?
