Seeing Inside the Sun
What Is The Sun Made Of?
The Sun has always served as our nearest laboratory in space, telling us more about the early universe and its makeup every time we study it in greater detail. We — our Sun, Earth, and selves — are the products of everything that happened before our creation. The initial event, the Big Bang To figure out the whole story of where we came from and how things got to be the way they are, though, we must turn to the stars that made us — and what made them. A reduced history of the universe In the beginning, there was hydrogen. Just 3 minutes after the Big Bang, hydrogen atoms — protons — and neutrons collided to create helium and a little lithium. So it would have remained, but for the stars that condensed from the expanding milieu.
You may know the Sun consists mainly of hydrogen and helium.

Meet the student
The sun is made of about three-quarters hydrogen, one-quarter helium, and some other heavier elements like carbon, oxygen and iron, in very small quantities. The hydrogen and helium are in a gas form. But the hydrogen H and helium He atoms are much closer together in the sun than what you might imagine. If you filled a balloon with H and He gas at the same average amount density as in the sun, the balloon would weigh about 25 pounds here on Earth. But, the density of the gas in the sun changes quite a lot, depending on its location in the sun. If you took the gas from the core of the sun, the balloon would weigh about 2, pounds.
Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. The more metallic a star, the more opaque it is since metals absorb radiation , and how opaque it is in turn relates to its size, temperature, brightness, life span and other key properties. Twenty years ago, astronomers thought they had the sun sorted. Direct and indirect ways of inferring its metallicity both gauged the sun as approximately 1. That is, astronomers should be able to use the helioseismological measurements to calculate the depth of an important boundary layer in the sun where radiation gives way to convection. This sequence of calculations should predict the same value for the metallicity as spectroscopers measure directly from sunlight. It does not.
