Globular clusters may contain hundreds of thousands of stars. M13 is estimated to consist of 300,000 to 500,000 stars. When we know that in space, on average, one light-year cube contains a couple of stars, one once again feels pretty small.

The stars of globular clusters are stars of the first generation (Population 2) and e.g. the Sun belongs to the stars of the second generation (Population 1). (The numbering convention here is illogical).

The stars contained in M13 are billions of years old. They were born almost at the same time (12-13 billion years ago) as, according to modern understanding, the entire universe was born (The Big Bang, about 14 billion years ago). The age of our solar system is estimated to be a "modest" 4.7 billion years (and if things go well, another 4.7 billion are left).

The stars of the first generation are metal-poor stars, the Sun is a metal-rich star. The stars of the first generation were formed almost exclusively of hydrogen and helium. Heavier elements were formed in the cores of these stars, which are then also found in e.g. the Sun and its planets. All matter around us heavier than hydrogen and helium, including the matter from which our bodies are formed, originates from the fusion reaction (thermonuclear reaction, fusion) that takes place in the cores of stars. Some even express it a bit poetically by stating that we are all daughters and sons of the stars.

English astronomer Edmond Halley, best known for the comet that bears his name (Halley's Comet), discovered M13 in 1714.
