There are two types of star clusters, open and globular. An open star cluster is a loose collection of stars, where a globular cluster
is a much tighter collection of stars. Globular star clusters tend to have a lot more stars in them.
All clusters below are outside of our solar system, but inside the Milky Way galaxy. There are star clusters in other galaxies also,
but I’ll only have the closer ones in our own galaxy below.
