What are the two main gases that make up many of the stars in our universe?
A
hydrogen, helium
B
hydrogen, nitrogen
C
helium, oxygen
D
oxygen, nitrogen
Explanation: 

Detailed explanation-1: -Most stars are made up of mainly two gases, which are hydrogen and helium.

Detailed explanation-2: -Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.

Detailed explanation-3: -Stars are made up of very hot gases. These gases are mostly hydrogen and helium, which are the two lightest elements. Stars shine by the fusion of hydrogen and helium in their cores.

Detailed explanation-4: -Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.

Detailed explanation-5: -While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.
