About it
A globular cluster is a ball of hundreds of thousands of stars held together by their own gravity, packed tightest at the middle. Its stars are very old, among the oldest in our galaxy, and the Milky Way has about 150 of these clusters circling it.
Tap it and the cluster breathes: it draws in, swells out and settles, the core first and the outer stars a moment later, while a wave of sparkle runs out from the middle. Near the middle of a real cluster, the stars are packed far more tightly than the stars around the Sun.
