What astronomers use to determine the composition of star?
Each element on the periodic table will emit a different color, it set if colors, when being burned. Astronomers look at the "Phase-Shift" of the color spectrum (or rainbow) that any given star emits. The Phase Shift refers to how the color... Read More »

How is a star's composition determined?
This is an interesting question. In the early universe, a few seconds after the big bang is thought to have happened, when everything had cooled down only hydrogen and helium could form. As the temperature dropped and gravity had more influ... Read More »
