What are the two primary gases that make up the composition of stars?
Answer
Hydrogen and helium
Stars are primarily composed of hydrogen and helium, which are the fundamental building blocks of their mass. This gas composition is crucial because the nuclear fusion process relies specifically on the conversion of hydrogen into helium within the star's core. The sheer mass of this gas creates the strong gravitational pull necessary to sustain the star, while the fusion of these elements creates the vast quantities of energy that allow stars to shine.
