Astronomers make first accurate measurement of oxygen in distant galaxy

[Ali Salamat]

UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and released into interstellar gas when stars die. Quantifying the amount of oxygen is key to understanding how matter cycles in and out of galaxies.

Both of Carbon and Oxygen are well known to exist in galaxies as a usual product of stellar fusion in larger stars.
Accurate measurments are nice, but they don't indicate anything of importance as far as I know.
