A galaxy is a vast, self-contained system of stars, gas, dust, and dark matter bound together by gravity. For much of history, galaxies were called “island universes” because they are separated by enormous distances of empty space.
Galaxies are not static. Stars orbit the galactic center, gas clouds collapse to form new stars, and older stars drift through long, stable paths. On the largest scales we can observe, galaxies are the basic building blocks of the visible universe.
Understanding galaxies is a major step up in scale. You are no longer studying individual objects, but entire systems containing billions of stellar lives happening at once.
