4About it
A galaxy is a huge family of stars, gas and dust held together by gravity. In a spiral galaxy, bright arms curl out from a glowing center. Our own galaxy, the Milky Way, is a spiral about 100,000 light-years across with hundreds of billions of stars, and the Sun takes about 230 million years to go around it once.
Here the spiral turns slowly as one piece while its stars orbit, the inner ones faster. The splash illustrates one idea for spiral arms: a moving density pattern that stars pass through, like traffic through a jam. Real galaxies can also have changing arms. Tap it to swirl the arms once around, fast, while the core flares. Pick the Milky Way or Andromeda style in the Splash tab.
