I am just wondering what substances we can find most on any stars's surface ?
How can they come into being ?
Thank you,

The most common substances found on stars are hydrogen and helium. These elements make up about 98% of the mass of the observable universe. Other common substances found on stars include carbon, nitrogen, and oxygen.
The substances present on a star greatly impact its color. The temperature and composition of a star determine the wavelengths of light it emits. For example, a star with a high temperature and a large amount of hydrogen will appear blue, while a cooler star with more red and yellow elements will appear red.
Yes, substances on stars can change over time due to nuclear fusion, which occurs in the core of stars. During nuclear fusion, lighter elements combine to form heavier elements, altering the composition of the star. This process is responsible for creating all of the elements beyond hydrogen and helium.
Scientists use a technique called spectroscopy to determine the substances present on a star. This involves analyzing the wavelengths of light emitted by the star and comparing them to known spectra of elements. By identifying the elements present, scientists can determine the substances on a star.
Yes, substances on stars play a crucial role in the evolution of the universe. As stars age and die, they release heavy elements into space, which can then be used to form new stars and planets. These elements are also essential for life as we know it. Additionally, the fusion reactions that occur on stars produce energy that helps to shape the universe and drive its expansion.
