98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such as carbon, oxygen, and iron.

It now turns out that our Galaxy is home to a stellar structure uniquely made of stars with extremely low metallicity, with a heavy element content 2,500 times lower than that of the Sun.
